Introduction to Bluetooth Technology Electronics Seminar Topic:

Bluetooth is a radio frequency specification for shout range, here the Bluetooth provides point to point and point to multi point voice and data transfer Bluetooth facilitates the replacement of gables from one device to another device b a short range radio link. With the help of Bluetooth we can operate some number of devices such as keyboard, mouse, printers, fax machines, headphones.

“The future of Bluetooth looks bright because it meets the basic need of connectivity in close proximity”

What is Bluetooth?

It is a specification that attempt to provide a standard method of wireless communication between various personal devices

How Bluetooth Technology work:

Design of Bluetooth micro chip is of 9mm x 9 mm  low cost and short Lange ladino link. Bluetooth is a wireless device which works for a short distance voice and data transmition it is mostly used for mobile and internet connection purpose. Using Bluetooth technology it is possible to connect 8 devices a time each pioneer support up to 3 Simultaneous voice devices.

                           Bluetooth technology is designed to be as sauces as a wire.

Transmission type and rates;

The baseband protocol combines circuit and packet switching sloth should be these for synchronous packet so that the packet do not assign ant of order

Circuit switching is of 2 types

Synchronous and asynchronous

Up to 3 synchronous data channels, and one synchronous and one asynchronous data channel can be support only one channel.

Synchronous channel support 64 kb/s transfer rate.

Asynchronous cannel can transfer 721 kb/s in one direction and 57.6 kb/s in other

Radio frequency and spectrum hopping:

The system is designed to use fast acknowledgment and frequency hopping. It is packet based after receiving the packet it will jump to new frequency by his it has less problem interface.

The Bluetooth radio chip functions at 2.4 gig cheats, it is unlicensed ism band. It separates the 2.4ghls frequency band into 79hops one MHz apart, starting 2.402 and ending 2.480. The standard frequency range is 10 centimeters to 10 metros, and it can be extended up to 100 meters by increasing Transmission power.

Data Transmission:

 The data is transmitted through asynchronous and synchronous. The asynchronous connectionless is used for data and synchronous connection oriented is(SCO) is used for “voice” Within a Pico net.  Time division duplex (TDD) is used by both ACL and SCO. And both of them support 16 types packet.

Introduction to Extreme Programming Seminar Topic:

XP used in agile methodology it shares the values from the manifesto and goes simple set of practice.Where there are many other methodologies they will try to answer the question. XP it is simple and asks “what is the simplest set of practices .I could possibly need and what do I need to do to limit my needs to those practices?”

It is simple to work beyond a narrow set of project criteria.

What is XP?

XP is a discipline of software development based on values of simplicity,communication, feedback and courage.

XP works with the whole tram by bringing them together, But by simple practice.

XP trams use a simple form of planning and tracking to decide what to do next.

The core XP practices for the above are called whole team planning game,small release and Acceptance tests.

Core practice:

There are 12 core practices are there that design XP. Teams new to XP focus on developing skills.

The practices can be described as a cycle of activities.

The inner circle describes the tight cycle of program.

The outer loop describing the planning cycle that occurs between the customer and programmar.The middle loop shows practices that help the team communication and coordinate the delivers of quality software.

WHOLE TEAM:

 All the team members sit together to do XP project.  This teamincludes the customer who provides the requirements, sets the priorities and stresses the projects.The team also includes testers to test the project and the projects also have some helper’s requirements and a coach is there to help the team and he will handle every are who works on the XP team.

PLANNING GAME:

Plan should be there before doing the task there are 2 points that need to be followed that are predict task that need to be completed on due date and get ready  to plan next step.

There are 2 key planning steps in XP they are

1. Release planning
2. Iteration planning

Introduction to Extensible Messaging and Presence Protocol Seminar Topic:

XMPP is a protocol that transmits small pieces of XML from one place to another place.

Also, it provides the services such as channel encryption, authentication presence, contact ,one-one messaging, multiparty messaging notification, service discovery, capabilities,  & advertise, structured data forms, work flow management, peer-peer media sessions.

Problem definition:

Security is main concern in communication protection of the data through XMPP is the concept to overcome, the problem of (SSL-HTTP): i.e.; secure sockets layer (SSL) works below the HTTP in layer architecture.

As XMPP is open in nature, it will minimize / eradicate the problem occurred above.

To overcome this problem:

This project main aim is to create an XMPP application for any organization and capable to connect any XMPP server.

1. XMPP works over persistent connections
2. XMPP becomes cheap
3. It is designed an event stream protocol
4. It is asynchronous: in asynchronous messaging system the participant is sending the message continuously and need not to wait for the response from the recipient. 

XMPP consists of XML stream that enable two entities on the internet to exchange message.

SYSTEN ANALYSIS:

EXISTING SYSTEM ARCHITECTURE:

In this project the protection depends on the implementation of the correctness by the web browser, server software and actual cryptographic algorithms supported.

Security is the main concern in communication protection of the data through XMPP is the concept to overcome, the problem of secure socket layer works below the HTTP in layer architecture.

PROPOSED SYSTEM ARCHITECTURE:

In this project the proposed system wants to create an XMPP application for an industry capable of connecting to any XMPP server.

There are some standard XMPP commands that use to build the application.

• Connect and disconnect
•   Register
•   Check roster
•  Send messages
•   Set status
•   Communicate presence

Introduction to  Antivirus Sandbox  Seminar Topics:

Overview:

From the  invention of computer,  there is Malware in the files which destroys the working speed of system called virus. As now the technology develops the new viruses emerges and malicious are develops in the software. Many Antivirus have invented to prevent this malware but it can bear and prevent the encrypting virus. So here we have invented the new Antivirus software called Sandbox.

This protect the documents and creative files from these encrypted virus by checking for the malware before downloading the file through the temporary folder. There are different types of malware like virus, Trojan horse, Worm.

Sandbox:

Sandbox is the computer security that runs the untrusted application and malware documents using the four components.  The building components are the documents that is to be tested, Sandbox container, sandbox controller, system resources.

Working of Sandbox:

The sandbox works based on two applications namely trusted and untrusted application. The trusted application can be accessible since the contents are fully trusted. But untrusted application should be processed in the sandbox. The sandbox works under the restriction such that the application should under the sandbox manager. The sandbox manager alerts the user if any sensitive resources are present in the application. This software works on its own simulation in different platforms. Sandbox gives compact resources for the strange programs to run according to the instruction. It avoids the boot up process through freezing process. The virus works and get manipulates in the simulated area through the thread process. The sandbox avoid this using APIs. If the files processed beyond the restricted area the simulated norman sandbox denies the application and makes it unworkable. 

Advantages of Sandbox:

1. Supports many Application Program Interface.
2. Works on many threads simultaneously.
3. Detect malicious programs.
4. Supports networks and messaging action.

The another most important application is protection of Day Zero Attack. This is done by proactive monitor. The stranger file entering the computer is desperate and prevent the infection from the danger. After this analysis the system will decide whether the file can enter or dispatch.

Sandbox safe pattern:

There are many models that operates in different environment. They are :

 1.Java Applets,

2. Security system.

3. Unix system.

4. Virtual emulator.

This Sandbox is more preferable than any other techniques like Digital Signature. Since DS scans the file but Sandbox process and operate on the virus files and can works on both trusted and untrusted model.

Introduction to  Storage Area Networks Seminar Topic:

Presently, in many organisations the storage capacity is increasing in a very big rate.  Network storage solutions are the one which can cure this state and provide a flexible connecting storage. There are three storage technologies available i) DAS ii) SAN iii) NAS.

In Direct Attached Storage, the Data is stored in hard disk which is attached to the individual server.  The data stored in the individual servers cannot be accessed when the server fails. Storage Area Network is a Network dedicated for storage devices. Additional Storage devices can also be attached to this network. Network Attached Storage is a local area network the data stored in the individual system connected to the LAN can be accessed.

Fibre Channel interface are used in Storage Area Network for Enterprise class storage arrays. With internal connection many modest priced storage array are available. Storage Arrays are the Logical unit for the host servers appears as a disk volume. Many number of external Fibre channel interface are available in Storage arrays in order to connect the host to the disk. Storage array controllers also provide features such as snapshots, clones, mirroring.

Centralised Backup System is linked to SAN to allow operational features in backup and restore operations.  Present backup systems are different, complex and very difficult to manage. The growth of internet, email, personal devices and integrated business made the data growth and there is a need to store and retrieve them.

As the Value of each data varies, Data Categorisation Strategy method is used to categorise the data into High criticality, Medium criticality, Low criticality and some time Mission critical/continuously available.

Reduced hardware costs, Reduced manage storage, Increased productivity, 24hours availability are some of the benefits of the Storage Area Network. But Installation and the configuration of this network is very difficult and time consuming one.

Introduction to Technical Seminar on Blue Eyes Technology:

The ability of the first generation RADARS are limited to detect only the object and they cannot sense the speed of the object.  From which we can only measure the echo on the screen and it don’t provide us much accuracy.

The intensity of the sound means the frequency of the sound waves seems to change when either the source or the observer are in relative motion. This wat we called as Doppler’s effect.

First the signal is sent from the unit to the moving object and then it receives the one which get reflects back. The speed of the object is obtained by comparing the signal sent and the one which we received.

Anti-radars: i) jamming device ii) detectors. Jamming Devices – SHF oscillators help in transmitting the signals to the speed cameras and collapse the measurement. Besides that the RADAR can detect these jamming signals and signal the police about this. A detector as a simple SHF receiver. These contain a microwave detector and alarm.

RADAR is not affected by rain or any other weather condition. Mist doesn’t have any relative motion with respect to radar and so there no affect in the measurement. The range of the RADAR to sense the speed of the object depends on i) the power of SHF oscillators’ ii) sensitivity of the detector. Power is low in oscillators and which are used in radars. The main problem in the Detector is signaling to noise ratio. RADAR works when a object nears it.

When several objects are moving at several speeds encounter at the RADAR shows the resulting Doppler signal consist of a mixture of signals at various frequencies. Presently the device gets collapsed and determines it as faulty. But now there are systems like DSP, to measure the speed of several objects simultaneously.

Introduction to Architectural Styles in Software Engineering:

Data flow Systems, Call-and-return systems Independent components, Virtual Machines, Data-centred systems are the Common Architecture Styles.  Architectural styles are set of system for pattern of Structural organisation. It contains the information about the components and the connectors and the set of constraints how they are combined.

Some of the common styles are i) Pipe and Filters ii) objects iii) implicit invocation iv)  layering v) repositories vi) interpreters vii) process control.

Pipes and Filters: Connectors are termed as pipes and Components are termed as Filters. This system assist reuse, concurrent execution, specialized analysis.

Data Abstraction and Object-Oriented Organization: Data and the operations associated with it are formulated into abstract data type called Object. Components are the objects. Connectors operated thorough certain procedure calls called methods.

Layered Systems:  It is organised in an order that each layer should serve the layer above. Connectors are lead by Protocols and inform layer interaction. Constraints are limiting interactions between the layers.

Repositories: It has two different components i) central data structure ii) collection of independent components which operate on the data-store. Traditional database can be used as a repository when input transactions select the processes to execute.  Repository can be a blackboard when the state of the data-store is for selecting processes. Blackboard model has three components i) knowledge source ii) Black board Data Structure iii) Control.

Interpreters: Imaginary machine created in software is interpreters. It shortens the gap between the computing engine and the programmers. It decodes the programme into machine language.

Heterogeneous Architectures: Combination of different styles are involved in creating a system. Components are developed using different methods. Connectors are decomposed into different systems. A single component can use different architectural connectors.

Introduction to  Real-Time Operating System Seminar Topic:

All the domestic systems that we use in the society are real-time systems and these follow timeliness. Real-time Operating system is to be designed for these real-time systems. These systems get the external inputs and process these into output with time constraints. If the timeliness is not maintained then the system is said to be failure. And there are three types of time constraints i) Hard ii) Soft iii) Firm.

Real-time Programme is p and it gets inputs in every t interval of time and event requires c computational time. Dead line for completing the computation is D. Predictability is a main concept in real-time system.

Design issues in Real-time system: All the behaviour of the system must be predictable. To achieve this all the components must be time bounded.  All the inputs are received by the systems and processed for outputs within a specified time else the system results in failure. Real-time behaviour is mandatory while designing a critical safety system.

Scheduling: These methods are introduced for maintaining the timeliness of the system. Depending on the system behaviour different scheduling paradigms are used.  Most scheduling problems are Numerical Process- complete.  Many algorithms are used to support the scheduling paradigms.

Real time Operating System is the integral part of the real-time system. These are different for the time-sharing systems. The main part of it is to process and schedule and to meet the requirement within the delay time.

Three types of operating system are i) small proprietary kernels ii) real-time extensions to commercial timesharing operating   systems iii) research kernels

Reflective architecture method is used to build a complex and flexible real-time system.  A  system  build on  reflective  architecture  is  reflects  upon  its  own  current  state  and  that  of  the  environment  to process the input correctly without time delay.

Introduction to  RSA Algorithm Seminar Topic:

The RSA scheme is a block chipper in which the texts are integers between 0 to n-1 for some n. RSA public key and RSA secret key are the two pairs of integers in this scheme.

Key generation i) two prime numbers were selected such that X ≠ Z. ii) predict n = X*Z. iii) – Predict Ø (n) = (X-1) (Z-1). What is Ø (n)?           Ø (n) is called the Euler’s Totient function. Two integers say X,Z are  relatively prime if and only if common positive integer factor is one. iv) choose any number e when gcd (Ø (n), e) =1; 1 < e < Ø (n). v) Predict the value of d – de ≡ 1 mod Ø (n) or d ≡ e^-1 mod Ø (n). In predition of‘d’ we need the multiplicative inverse of ‘e’ modulo Ø (n). vi) Public key of RSA is {e, n}. vii) Private key of RSA is {d, n}. 

Encryption Procedue: If we desire to send a message as m, then Ciphertext(C)= M^e mod n.

De encryption Algorithm: If the ciphertext is C, then the original message or the plaintext- M=C^d mod n. 

Application: encryption and de encryption of the message is done using the RSA algorithm for making the communication secure. It is used for digital signature and key distribution. Remote banking and e-commerce are the areas were RSA Algorithm used.

RSA Algorithm is more secure method of encryption and de encryption for communication system. It is more secure than DES and others. Elliptic Curve Cryptography(ECC) is a competing one for RSA.
