Implementing-Signal-Protocol

Sabanci University CS411 - Cryptography Course Project
Implementation of the Signal Protocol as a demonstration of secure end-to-end encryption.

• Phase 1: Developed software for the Public Key Registration
• Phase 2: Developed software to receive messages from other clients
• Phase 3: Developed software to communicate with other clients

Used Technologies/Algorithms:

• Elliptic Curve Cryptography (ECC) for key exchange protocol and digital signature algorithm with NIST-256 curve
• Hash based MAC (HMAC - SHA256) function is used for authentication
• AES128-CTR is used for message encryption
