摘要：
As a widely used symmetrical block cryptographic algorithm, RC5 has the characteristic of variable block length, variable round number and variable key length to satisfy the security need of different application environment. This paper presents an area efficient and reconfigurable hardware circuit. Using loop unrolling technology, the hardware circuit costs less resources by 74.7% compared to the conventional area optimized implementation of RC5 algorithm.
