Enhanced Authentication Protocol EAP-TTLS using encrypted ECDSA
The growing trend of wireless networks and risks associated with them has led to the development of authentication and application of stronger cryptographic methods to maintain a more robust security. This article examined and compared two types of developed authentication protocols to provide an alternative method using strong cryptographic methods. The common EAP-TTLS method uses RSA algorithm for encryption and SHA-1 hash algorithm. In this article, the new method called alternative EAP-TTLS method uses Elliptic Curve Digital Signature Algorithm (ECDSA) and the secure hash algorithm (SHA-256) to provide stronger security and higher efficiency. This alternative method and the mechanism used in it is fully explained and compared with the common EAP-TTLS method. Results obtained indicate that the alternative algorithm provides strong security, high speed, and more applicability with the same level of memory usage compared to the common EAP-TTLS.
