This document Security and Cryptography Technical PPT presents three ways for strengthening public key cryptosystems in a way that they become secure against ciphertext attacks. The first is strengthening method, based on one-way hash functions, the second on universal hash functions, and the third on digital signature schemes.

There are two kinds of cryptographic security, computational security and unconditional security. Cryptography occurs in a physical world of communication where nobody can have complete information about system state.

Using a public key system, this technique provides secure messages transmission to exchange secret keys. Ranging from secure commerce and payments to private communications and protecting passwords, many aspects to security and applications are described, one among is cryptography. Security is the protection against loss, danger, and criminals. It has to be compared and contrasted with continuity, safety, and reliability.

Cryptography is study of protecting information. Today, cryptography is meant to be a branch of both computer science and mathematics. It is affiliated with information theory, engineering, and computer security. This technology is applied in many fields like security of ATM cards, computer passwords, and electronic commerce.

Cryptography is closely referred to encryption. It is the process of converting plaintext into ciphertext or conversion of ordinary information into unintelligible gibberish. Conversion of unintelligible ciphertext to plaintext is termed as decryption. Cipher is a pair of algorithm that creates the encryption and reverses the decryption. It is the technology of writing in secret code.

Conclusion:

This document describes how cryptography operates. It is an interesting field where the work is done in secret. Time is the only genuine test of cryptography. The strength of cryptography depends on the choice of the keys. Cryptographic schemes have employed many trust models like Kerberos. Secrecy is not the key to best cryptography, but the best algorithms are those which are well-documented and well-known.

Secure Mobile Agent Final Year Btech Seminar Technical allows intelligent operation with less human interaction in software system. A big challenge to deployment of mobile agents to prevent unauthorized access to resources between interacting systems can act maliciously both as host or agent. In a heterogeneous computing environment, a secure mobile agent system has the ability for transmission and secure management of mobile agents. It provides security managers for the users.

Mobile agent is the latest discussion in the domain of distributed system. This agent technology allows in designing innovative solution by complementing other method simply by including code mobility, improved network, machine based intelligence, and data management possibilities.

Motivation and Approach for Mobile Agents: Mobile software agents can realize interconnections between data sources as proactive components. With respect to security, flexibility and data compression, mobile agents offer the optimum solution with their benefits.

A mobile agent is defined as a program migration from host to host in a network of heterogeneous computer systems. It fulfills the task of its owner. It works autonomously and communicates with host systems and other agents. Migration of agents depends on an infrastructure that provides the necessary services in the computer network. This infrastructure is a set of agent servers that run on nodes.

Goals of mobile agent system: The agent has to identify, trust, and communicate in a secure fashion. The code should be transmitted. The execution host must restrict the actions of the mobile code. An agent system must be authenticated.

Conclusion:

From the above discussion, mobile agent plays an important role in designing mobile agent system security. It may be concluded that mobile agents are not yet secured enough. The complete mobile agent systems security is dominated by the policy certificates depending on the agents and hosts verification. The mobile agents will become the integral part of the today’s commercial market within a short period of time.

Small Computers System Interface (SCSI) Seminar: SCSI is a kind of interface which is used for computer components like hard drives, optical drives, scanners and tape drives. The Small Computers System Interface (SCSI) was originally developed by IBM.

There are three components mentioned in any SCSI system. They are Controller, Device, and Cable.

The heart of SCSI is the controller. It acts as an interface between all devices on SCSI bus and the computer. It is also called host adapter. It can be a card which is plugged into a slot. It can be built exactly into the motherboard. There is a SCSI BIOS on the controller. This is a small ROM or Flash memory chip that has the software needed to access and control the devices on the SCSI bus.

Every device on the SCSI bus has a built-in SCSI adapter which allows it to interface and communicate with SCSI bus. Embedded SCSI devices are those devices on which adapter are built. Each SCSI device must have a unique identifier (ID). Depending on specification, an SCSI bus has ability to support 8 or 16 devices. Using a resistor circuit, each end of the SCSI bus is closed which is called Termination. There are only two terminators which are used one for each end of the SCSI bus.

There are three jumpers which are used to describe the SCSI ID. This interface is not a happy participant in multiple host scenarios. It has been spindled, folded, and mutilated to the point and grudgingly allows two hosts to talk to a given device string.

Conclusion:

SCSI has a high speed communication bus. It allows connectivity both from inside and outside the computer. The SCSI is of three types. They are SCSI-1, SCSI-2, and SCSI-3. Termination of SCSI interface can be done either in active or passive mode. SCSI is smarter bus than IDE.

RSA Algorithm Computer Science Seminar Topics 2011 was discovered by three scientists, Ron Rivest, Adi Shamir and Len Adleman. This scheme is a block cipher where plain text and cipher text are integers between 0 and n-1 for some value n. The typical size of n is 1024 bits or 309 decimal digits. It is a public key encryption RSA scheme.

The two pairs of integers {e, n} and {d, n} are used in this scheme. First of them {e.n} is called the RSA public key and the other one {d, n} is called the RSA secret key. The sender uses the public key to encrypt the message into cipher text.

It is expressed as C =  M^e mod n.

Here C is the cipher text and M is the message or the plane text. At the receiving end, the receiver receives the cipher text C and decrypts C into M using secret key {d, n}.

KEY GENERATION: The method of Key Generation consists of following steps:

1. Select two prime numbers say p and q randomly Where p ≠ q.

2. Calculate n = p *q.

3. Calculate Ø(n) = (p-1) (q-1).

Applications of RSA are: It is widely used for encryption and decryption in message process to get secure communication. It is used for digital signature. It is used for key distribution. It is used in e-commerce and remote banking.

Conclusion:

It is concluded that RSA is a powerful scheme most widely utilized for digital signature and encryption/decryption. It is more secure than DES and other schemes. It is known that that the key length RSA use has increased for security purpose. Using RSA, it has a heavier processing load on applications. This scheme has ramified especially for electronic commerce sites that have large numbers of transactions. RSA is fundamentally an easy method to explain than ECC.

Robotics Engineering Seminar Download: Robotics is the technology and science of robots, their manufacture, design, and application. Robotics must have a working knowledge of mechanics, electronics, and software. 

The person working and designing in the field is a roboticist. The robot is structured mechanically which is called a kinematic chain. It functions analogously like a human skeleton. This chain contains actuators (its muscles), links (its bones) and joints.

Autism is a permeate developmental disorder which is characterized by and communicative and social impairments. Social robots respond and recognize to human social humor with particular behaviors. 

The technology utilized in the construction of social robots can be a unique tool in the field of autism. This report discusses how social robots made an impact in the field of diagnoses, treatment, and understanding of autism.

The social disability of autism is a profound way affecting a human’s capacity for feeling and understanding other people and to establish reciprocal relationships. Today, this tool remains a specified disorder.  There is no genetic screening, no blood test, and no functional imaging test for diagnosing of autism.

Robots need motivation and engagement in therapy. Many studies have demonstrated that robots form a high degree of engagement and motivation in tasks to interact socially with human therapists. Only three facial expressions are obtained from the Playtest device and the ESRA robot.

The fine-grained analyses of social capabilities resulted from work on diagnostic and therapeutic applications. They have the capability to enhance our understanding of autistic disorders.

Conclusion:

Expressing effect and recognizing are the important part of social participation. Their social cues are growing up to comprehend social nuances in social behavior or communication or to blend during the everyday interaction. This research represents an approach for the teacher to understand emotional expressions, guides recognition to teach emotion recognition to autistic children with a heterogeneous disorder. It is designed to offload few more tedious part of the work.

Resource Sharing On Internet Computers Presentation: The technology developed as storage is known as the Internet Backplane Protocol (IBP). It is designed to test hypothesis and explore of implications. It is our basic tool in the logistical networking technology. It is a field motivated by storage and viewing data transmission within unified framework.

Internet Backplane Protocol (IBP) has been developed for the support of domain and application and optimization of data movement. This technology is used for managing storage within the network filed. It allows an application to implement inter-process communication. With this implementation of data staging operations, locality can be exploited and scarce buffer resources are managed more effectively.

In the internet world, a large distributed system provides a communication service to computer systems at its periphery. The consideration of robustness and scalability enables its designers to select a stateless model. Routers do stateless data transfer operations and control is calculated by routing algorithms.

It is to remember that the designers of large-scale computation systems often follow shared memory model because the functional model has undesirable limitations on performance and control. Increasingly the design of Internet-based information systems is utilizing shared-memory approaches which support the management of distributed data rather than access.

In order to have uniform interface to state management that is better integrated with the Internet, the Internet Backplane Protocol (IBP) has been defined. IBP can be viewed as a mechanism to adjust either remote files or communication buffers.

Conclusion:

 This approach is based on the Internet model of resource sharing. It also represents one general method of using storage resources to create common distributed infrastructure that share communication bandwidth. It is designed on the model of IP to allow storage resources that are shared by users and applications for maintaining necessary security and protection from abuse. IBP is mainly for the intermediate resource management components and accessible to every end-system

Remote Method Invocation Technical CSE Presentations technology is first introduced in JDK 1.1. It is highly network programming to a higher plane. RMI is very easy to use. It is a remarkably powerful technology and displays the average Java developer to a complete new paradigm, a world of distributed object computing. It has evolved since JDK 1.1. It has been significantly upgraded under Java 2 SDK.

The primary goal of RMI developer is to enable programmers to develop distributed Java programs with same syntax and semantics which is used for non-distributed programs. They had to map Java classes and objects work carefully in a single Java Virtual Machine (JVM) to a new model.

The RMI architecture explores differences from the distributed or remote Java objects with the character of local Java objects. This architecture defines the character of objects, how and when exceptions can occur, how memory is managed, and how parameters are passed to and returned from remote methods.

The RMI architecture depends on one main principle that is the definition of behavior and the implementation of behavior which are separate concepts. RMI enables the code that defines the behavior and the code implements the behavior to remain separate and to run on separate JVM’s.

The implementation of the remote service is coded in a class. Hence it is to remember that interfaces define behavior and classes define implementation which is the key for understanding RMI. The RMI implementation is built on three abstraction layers. They are Stub and Skeleton layer, Remote Reference Layer, and Transport Layer.

Conclusion:

RMI is an implementation in Java. The goal of RMI architecture was to create a Java distributed object model. That integrates into Java programming language and the local object model. RMI architects have successfully created a system that extends robustness and safety of the Java architecture to the distributed computing world.

Real Time Task Scheduling Download Seminar Report: When rigid time requirements is placed on a processor or the flow of data than a real time task scheduling is utilized. Hence it is used as a control device in a dedicated application.

The aim of real time scheduling is to execute its critical control tasks with the appropriate deadlines. The allocation/scheduling problem: Given a set of tasks, resource requirements, task precedence constraints, task characteristics, and deadlines and to devise allocation/schedule on a system.

A task requires one or more resources and requires some execution time on a processor. Tasks may have precedence constraints and may require some amount of memory or access to a bus. The physical resource may be exclusive or non-exclusive depending on the operation to be performed.

The total time which all the data required to begin executing are available is the release time of a task and the time taken to complete its execution is the deadline time. The deadline time may be hard or soft depending on the nature of the task. The absolute deadline minus the release time is the relative deadline of a task.

There are three types of tasks. They are periodic, sporadic or aperiodic. If task Ti is released periodically then it is a periodic task. If the task is not periodic then it is a sporadic task but invoked at irregular intervals. Sporadic tasks are sometimes also called a periodic task.

Conclusion:

The process of deciding which task to execute next is called dispatching. Simple priority assignment policies regard with time constraints associated with a task. Priority assignment is scheduling of tasks with precedence constraints, timing constraints resource constraints and arbitrary values on multi-processors. 

There two main considerations are schedule construction and feasibility checking. Hence the complexity of the algorithm is not dependent on a number of tasks but depends only on the number of processors.
