In this paper, a low-complexity Programmable Cellular Automata (PCA) based reconfigurable architecture is proposed. Through simple configurations, it cannot only be used in the PCA-based block cipher of symmetric-key encryption, but also can be configured to be an efficient versatile modular multiplier in GF(2m), an essential operation in public-key cryptography. The proposed reconfigurable hybrid-crypto architecture has a regular structure and is very suitable for high speed VLSI implementation, increasing the flexibility of security schemes and reducing the total cost of the hybrid cryptosystems. Moreover, the low-cost serial implementation of this reconfigurable architecture is feasible in restricted computing environments, such as embedded systems and wireless devices.
