TL;DR: In this paper, a stream cipher based algorithm for computing message authentication codes is described, which employs the internal state of the underlying cipher to minimize the required additional-to-encryption computational effort and maintain general simplicity of the design.
Abstract: A stream cipher based algorithm for computing Message Authentication Codes is described. The algorithm employs the internal state of the underlying cipher to minimize the required additional-toencryption computational effort and maintain general simplicity of the design. The scheme appears to provide proper statistical properties, a comfortable level of resistance against forgery attacks in a chosen ciphertext attack model and high efficiency in software implementations.
