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 EAPTTLS method uses RSA algorithm for encryption and SHA-1 hash algorithm. In this article, the new method called alternative EAPTTLS 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.
