Abstract:

 An ideal function of self-updating Hash chain authentication was proposed by using the framework of universal composable. A real protocol based on one time signature ideal function was designed. It proved that the protocal can realize the ideal function with secure pseudorandom function and cryptographic secure Hash function.
 

Key words: protocol analysis; universal composable; ideal function; Hash chain; self-updating
