IRC Chat Server

Jan 1, 2024 · 1 min read

Implemented a authentication feature for a KDC based multi-threaded IRC chat server using needham schroeder protocol. There is a central Key Distribution Server which acts as a trusted party which clients can use to authenticate themselves. The server is implemented in C using socket programming.

Further feautures added to needham schroeder protocol are:

  • Prevention of replay attacks
  • Bidirectional authentication between client and server
  • Encryption of messages using AES along with HMAC for integrity check
  • Random IV generation for each message
