An Asymmetric Authentication Protocol for Mobile Devices Using Elliptic Curve Cryptography

摘要

In recent times, the majority of e-commerce applications are designed using asymmetric cryptography to assure the authentication of the concerned parties. Conversely, an increasing requirement for mobile devices has geared a shift towards mobile e-commerce applications. This research work emphasizes that the existing authentication protocols, based on RSA asymmetric cryptography are not suitable for such devices due to their confines in computing power, memory capacity, key sizes and cryptographic support. For that reason, an efficient protocol for resource constrained platforms that attain a level of security similar to the one achieved by the protocols in use today is designed and implemented. This protocol is based solely on Elliptic curve asymmetric cryptography and the results demonstrate that the performance achieved is good in contrast to RSA.
