A Fast Correlation Attack Algorithm Based on Sequence Decoding
Pla Information · 2006
Fast correlation attack is one of the important cryptanalysis method for stream ciphers. This paper presents a new fast cor- relation attack algorithm which based on error- correcting codes. First, transferring the linear block code to a convolutional code with low rate using special parity check equations; then obtaining the key from squence decoding algorithm of convolutional code. The new algorithm notably reduces the decoding complexity of the fast correlation attack algorithm from .
