New Technique for Decoding Codes in the Rank Metric and Its Cryptography Applications

New Technique for Decoding Codes in the Rank Metric and Its Cryptography Applications We present two new algorithms for decoding an arbitrary (n, k) linear rank distance code over GF(q N ). These algorithms correct errors of rank r in O((Nr)3 q (r−1)(k+1)) and O((k + r)3 r 3 q (r−1)(N−r)) operations in GF(q) respectively. The algorithms give one of the most efficient attacks on public-key cryptosystems based on rank codes, as well as on the authentication scheme suggested by Chen. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Problems of Information Transmission Springer Journals
