Side Channel Attacks on Irregularly Decimated Generators

Cryptanalysis traditionally has been the study of ciphers from a mathematical point of view. These attacks exploit the algorithmic nature of the cipher and compromise the security. Modern ciphers are designed to prevent these known attacks, making cryptanalysis difficult. However, in recent years there is a new class of cryptanalysis that studies the implementation weakness of ciphers. These attacks study the physical information (time, power, etc) leaked by the product ciphers and compromise it. Even strong ciphers like AES and RSA are also vulnerable to side channel attacks.
