Analysis and Countermeasure on Vulnerability of WPA Key Exchange Mechanism

Key exchange protocols play a vital role in symmetric key cryptography. The transfer of private key through the secured medium is a challenging task because every day the intruders are evolved and the attacks are increasing constantly. The existing key exchange protocols such as Diffie-Hellman, Elgamal, and MQV, etc. are the old methods and many attacks happened on those protocols. That challenges demanding new protocol or methodology of transferring secret key between the parties. The paper proposes a new, secured, less computational overhead key exchange mechanism using short message service available in the cellular networks. GSM-SMS is a highly established secured channel and the research uses this facility to transfer the key between senders to a receiver of the symmetric key cryptosystem. The private key no need to reveal to third parties or even the receiver because the sender can directly communicate to the decryption system through the mobile SMS. After the decryption process, the secret key will be destroyed immediately. There is no possible attack during the key transfer and loss and error of the communication are very less.

Key Exchange Protocol

Security is utilized to keep the information safe. Online resources, e-commerce, internet banking and a lot of similar services are protected by use of well-known protocols such as Secure Socket Layer (SSL). This protocol makes use of the RSA key exchange protocol for authentication. New innovations and boost ups in the computational power of supercomputers today makes it quite easier than before to break through RSA and consequently decrypt the payload transferred over SSL. In this research demonstrates the use of SSL; how to utilize it in the best shape? We also discuss reasons of why we need to improve its strength. The proposed solution is to replace the RSA key exchange mechanism utilized in SSL with Elliptic Curve Cryptography (ECC).
