چکیده
We give a new deenition of keyed hash functions and show its relation with strongly universal hash functions and Cartesian authenti-cation codes. We propose an algorithm for a secure keyed hash function and present preliminary result on its performance. The algorithm can be used for fast (about twice the speed of MD5) and secure message authentication.

متن کاملOn the Indifferentiability of the Integrated-Key Hash Functions
Most of today’s popular hash functions are keyless such that they accept variable-length messages and return fixed-length fingerprints. However, recent separation results reported on several serious inherent weaknesses in these functions, motivating the design of hash functions in the keyed setting. The challenge in this case, however, is that on one hand, it is economically undesirable to abun...
