Abstract :
Modular multiplication is essential in cryptographic algorithms (e.g. RSA), as it determines the performance of the entire cryptographic operation and its reliability is crucial for the system security. In this paper, we propose a high-radix Montgomery Modular Multiplication (MMM) implementation and conduct an exploration to find the optimal radix. Also, a concurrent error detection circuit with 99.9% detection rate, small area and power overheads (2.24% and 1.46% respectively) is proposed to protect the MMM against fault attacks and natural faults.
