Abstract. The CBC-MAC or cipher block chaining message authentication code, is a well-known method to generate message authentication codes. Unfortunately, it is not forgery-secure...
In this paper, we revisit the security of several message authentication code (MAC) algorithms based on block ciphers, when instantiated with 64-bit block ciphers such as DES. We e...
We define a new mode of operation for block encryption which in addition to assuring confidentiality also assures message integrity. In contrast, previously for message integrity...
We put forward a new model for understanding the security of symmetric-key primitives, such as block ciphers. The model captures the fact that many such primitives often consist of...
