Securing Aggregate Queries for DNA Databases Project

Concept:

Efficient scheme which ensures that plaintext data cannot be recovered as long as the adversary has access to at most all but two ciphertext blocks, even when the encryption key is exposed.

Owner:

  • Owner has to register to get login.
  • File Upload: owner can upload the file to cloud . this file will be visible to cloud-A who will generate private key.
  • View Files: owner can view the uploaded files.
  • Upload to Cloud: owner can upload the files into cloud with a valid privatekey which is generated by cloud A file will be split into two parts and will be stored in two diiferent accounts in Drive-Hq cloud.

User:

  • User has to register to get login.
  • View files and send request: user can view the cloud files and he can send request to cloud
  • Verify keys and download: To download total file User need to verify splited part-0 file from cloud-a with 1st key which is sent to user mail by cloud-a and veirfy part-1 splited fle from cloub-b with 2nd key which is sent to user mail by cloud-b.
  • If both key are matched then only user can download if not he is malicious user.

Cloud A:

  • Cloud has to login
  • View Files: cloud A can view the files which are uploaded by user and cloud can provide private key for respective files
  • Split files: cloud A can view part of splited files which are uploaded by owners.

Cloud B:

  • View user request: cloud-b can view user requests and can give public keys to requested user to download files.
  • Split files: cloud A can view split files

Attacker module:

  • Attacker will search for keys and download part from cloud-a but he cant view that data because he can get only partial part-0 of file. Attacker dont know how to get part-1 and where it was stored.
