The State()-of-The()-Art of Research on Block Cipher Mode of Operation
Wenjun Wu · Chinese Journal of Computers · 2006
A mode of operation,or mode, for short,is an algorithm that features the use of a symmetric key block cipher algorithm to provide an information service,such as confidentiality or authentication.A good mode can remedy some weaknesses of block cipher,on the other hand,a poorly designed mode may be insecure even though the underlying block cipher is good.The research of mode always goes with the development of block cipher.With the advent of new block ciphers,there is a need to update long-standing modes of operation and an opportunity to consider the development of new modes.From the ECB,CBC,CFB and OFB modes of DES to CTR,CCM,CMAC,GCM and AESKW modes of AES,the authors introduce the design rationales,security model,research results and the state-of-the-art of research on block cipher mode of operation in this paper.
