Security and Composition of Multi-party Cryptographic Protocols
Ran Canetti
Abstract
We present general definitions of security for multiparty cryptographic protocols and show that, using these definitions, security is preserved under a natural composition method. The definitions follow the general paradigm of known definitions; yet some substantial modifications and simplifications are introduced. In particular, `black-box simulation' is no longer required. The composition method is essentially the natural `subroutine substitution' method suggested by Micali and Rogaway. We first present the general definitional approach. Next we consider several settings for multiparty protocols. These include the cases of non-adaptive and adaptive adversaries, as well as the information-theoretic and the computational models.
