Abstract

Rabi and Sherman [RS97] presented novel digital signature and unauthenticated secret-key agreement protocols, developed by themselves and by Rivest and Sherman. These protocols use ``strong,'' total, commutative (in the case of multi-party secret-key agreement), associative one-way functions as their key building blocks. Though Rabi and Sherman did prove that associative one-way functions exist if \p\np\p \neq \np, they left as an open question whether any natural complexity-theoretic assumption is sufficient to ensure the existence of ``strong,'' total, commutative, associative one-way functions. In this paper, we prove that if \p\np\p \neq \np then ``strong,'' total, commutative, associative one-way functions exist.
