Three-Tier authentication and secure key exchange over insecure channel

Authentication and key exchange securely over the insecure channel is a big deal these days. It plays vital role in big data applications. Mutual authentication is generally relay at the single channel between two users. An attacker performs the passive attack (traffic analysis) and switch towards the active attack Three tier authentication system checks the authenticity of the client at three independent channels and if found secure then only allow the client to get the services from the application server. Two intermediate servers will provide two-split passwords and the application server will provide the complete password. These intermediate servers will forward the split password towards the main application server which compares and finds the similarities between them. Whole communication is based on public key cryptography to achieve mutual authentication, confidentiality and integrity of the message.
