Abstract

Both one-to-one and one-to-many correspondences between events, sometimes known as injective and non-injective agreements, respectively, are widely used to specify correctness properties of cryptographic protocols. In earlier work, we showed how to typecheck one-to-one correspondences for protocols expressed in the spi-calculus. We present a new type and effect system able to verify both one-to-one and one-to-many correspondences.
