Many security properties of cryptographic protocols can be all formalized as specific instances of a general scheme, called Generalized Non Deducibility on Composition (GNDC). This scheme derives from the NDC property we proposed a few years ago for studying information flow in computer systems. The theory is formulated for CryptoSPA, a process algebra we introduced for the specification of cryptographic protocols. One of the advantages of our unifying GNDC-based theory is that that formal comparison among security properties become easier, being them all instances of a unique general property. Moreover, the full generality of the approach has helped us in finding a few undocumented attacks on cryptographic protocols.

Abstract
Many security properties of cryptographic protocols can be all formalized as specific instances of a general scheme, called Generalized Non Deducibility on Composition (GNDC). This scheme derives from the NDC property we proposed a few years ago for studying information flow in computer systems. The theory is formulated for CryptoSPA, a process algebra we introduced for the specification of cryptographic protocols. One of the advantages of our unifying GNDC-based theory is that that formal comparison among security properties become easier, being them all instances of a unique general property. Moreover, the full generality of the approach has helped us in finding a few undocumented attacks on cryptographic protocols.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
