Abstract. Authentication watermarking is a hidden data inserted into an image, in order to detect any alterations. It seems to be almost impossible to design a really secure authen...
We consider message authentication codes for streams where the key becomes known only at the end of the stream. This usually happens in key-exchange protocols like SSL and TLS wher...
The proposed broadcast authentication protocols for wireless sensor networks can be divided into two categories: protocols based on digital signature and protocols based on improv...
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...
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...
