ASBDIA-PROTOCOL

ASBDIA(Algebraic Signatures-Based Data Integrity Auditing) is Challange response type protocol where cloude-user can periodicaly check integrity of they data which is stored on cloude (third party service provider) based on giving challange to cloud-service-provider. it check integrity of stored-data with help of cryptography hash-signature. .

Technolgoy Stack

Platform: C++ && Crypto++ Library.

Mode: CLI(Command Line Interface).

Utility: Socket.

Terminology

Admin: Client.

Prover: Cloud Service Provider.

Challanger: Truted Third Party.

Working

• Admin,Prover & Challanger servers start.

• Challanger periodicaly give challange to Prover with randomly.

• Attaker Script run on Prover side for randomly change bits of Admin data.

• In Next few Challange, Challanger able to identify that data is change, so it immediatly report to Admin.

Design

• High Level View

• First Admin generate Signature Of Data using this pattern & send it to Challanger, and then upload data to cloud.

• When Prover get challange from challanger it start generating its proof of work. send it work to challange back.

• Recieving proof of work from Prover, challanger start validating orignal-data using recieved information & Signature of data that it have.
