摘要
Abstract
AES-OTR algorithm is a campaign of CAESAR competition,the competition is sponsored by the international cryptography Association IACR and launched by Japan in order to collect authentication and encryption algorithm to the whole world.AES-OTR has successfully entered the third round of screening by virtue of its unique advantages.Encryption and authentication of AES-OTR algorithm are all based on block cipher AES.But the relative independence of each block and label generation method is relatively simple make AES-OTR exists effective methods of forgery attack.For the disadvantages of this algorithm,this paper shows forgery attack on AES-OTR in the known plaintext conditions and association data and public message number are reused.At the same time,the validity of the methods is proved,and the probability of the success of the method is calculated.关键词
