Research and Simulation of Timing Attacks on RSA
Chen Cai-sen · Computer Technology and Development · 2010
Time information from cipher device to perform encryption/decryption could be captured by attacker.It is easy to conjecture the secret key and then break cryptosystem.Gives a research on RSA public-key algorithm and timing attacks against RSA,analyzes the process of modular exponentiation,and illustrates the theory of timing attack on modular exponentiation.At the same time,it is simulated and the result shows that RSA algorithm against timing attacks is vulnerable.Also it proposed that it can get the secret key faster and preciser in timing attack than other traditional attacks.In the end,discuss how to defense the timing attack using countermeasures.
