Task-PIOA is a modeling framework for distributed systems with both probabilistic and nondeterministic behaviors. It is suitable for cryptographic applications because its task-bas...

In 1999, two signature schemes based on the flexible RSA problem (a.k.a. strong RSA problem) were independently introduced: the Gennaro-Halevi-Rabin (GHR) signature scheme and the...
We describe a new algorithm for analysing security protocols that use XOR, such as key-management APIs. As a case study, we consider the IBM 4758 CCA API, which is widely used in t...
We study cryptographic modeling and encryption-based design techniques for guaranteeing privacy of data that is first stored in some type of computer memory and then deleted. We ...
At TCC 2005, Backes and Cachin proposed a new and very strong notion of security for public key steganography: secrecy against adaptive chosen covertext attack (SS-CCA); and posed ...
