A Novel Architecture for Secure Communications in Mobile Systems

Explosive growth in the number of mobile communication devices necessitates the need for more secure and energy-efficient schemes. They also pose additional constraints like limited battery-life and computational power, which add new dimensions to the conventional secure communication problem. In such a scenario, the need for newer paradigms and schemes cannot be over-estimated. This paper discusses one such approach, in the form of a secure & mobile-platform-conducive architecture design, which is a thoughtful application of existing algorithms like RSA and the Elliptic Curve Cryptography (ECC). The core of this architecture lies in the fact that RSA public key operations are computationally much less intensive than the corresponding private key operations, while it is the other way around in ECC. Tests have been conducted to verify the claims. Results have shown that this architecture works better than the other architectures which can be employed in mobile communications.
