| Abstract: | Timing attacks are used to collect and analyze the valuable information of algorithms from the different amounts of time,which are taken when cryptographic devices are working,and they are the most effective side channel attacks.This paper analyzes the process of the RSA decryption algorithm on the research in RSA encryption algorithm and timing attacks,illustrates the theory of timing attack to RSA bases on the modular exponentiation and the square and multiply algorithm,and discusses how to defense timing... |
