Abstract |
Handheld devices like mobile phones, PDAs have become very popular. They need modern security mechanisms such as the SSL protocols for their connectivity to the unsafe Internet. On the background of security mechanisms, cryptographic approaches are used. The most widely used public key cryptography approach in the Internet is RSA. But RSA needs heavy computing resources such as CPU computing power and memory which handheld devices cannot offer in large scale. Cryptographic approaches should be used in such a manner that they do not affect the user experience of the system. Keeping this in mind, researchers all over the world continuously try to discover newer approaches to the traditional RSA cryptosystem. A number of RSA variants were discovered with this notion. Further a relatively new concept called elliptic curve cryptography has caught the eyes of researchers in recent years with the view that it provides equal security with lesser bit-length of keys than RSA. In this context, this study focuses on the performance benefits of using RSA variants and elliptic curve cryptography over the traditional RSA cryptosystem so as to suggest an effective working cryptographic model for resource-constraint handheld devices. |
