This article presents a sort of new method of preventing side channel attacks based on the fixed-base comb.

We put forward a fast algorithm for point multiplication by use of projective coordinates,and analyze the possible side channel attack during the process of point multiplication.

Sidechannel attacks exploits various kinds information emitted by temperresistant devices or chips that perform cryptographic computations, evading the essence of reporting conclusive experiments where actual cryptographic algorithms are successfully attacked Electromagnetic attacks and power attacks are two kinds of sidechannel attacks The two are similar, but each has its own characteristi

Method on building self-healing cryptosystem resistant to side-channel attack;

This paper presents a new type of side channel attack based on Cache behaviors.

Since the introduction of the so-called Side Channel Attack, which makes use of the information leaked through encryption process, such as power consumption, timing and electromagnetic radiation, solely updating encryption algorithm and protocol is not enough to provide security for encryption system.

As one type of side channel attacks, fault analysis is a popular cryptanalysis.

A general countermeasures against time domain side channel attacks is to insert random delays into the executing sequence of cipher algorithm,in which the interesting operations will occur at different time in multi runs of the cipher.
