| Abstract | We study session key distribution in the three-party setting of Needham and Schroeder. (This is the trust model assumed by the popular Kerberos authentication system.) Such protocols are basic building blocks for contemporary distributed systems---yet the underlying problem has, up until now, lacked a definition or provably-good solution. One consequence is that incorrect protocols have proliferated. This paper provides the first treatment of this problem in the complexity-theoretic framework of modern cryptography. We present a definition, protocol, and a proof that the protocol satisfies the definition, assuming the (minimal) assumption of a pseudorandom function. When this assumption is appropriately instantiated, our protocols are simple and efficient. |
