Non-malleability is an interesting and useful property which ensures that a cryptographic protocol preserves the independence of the underlying values: given for example an encryp...

Abstract. Location-dependent services are services that adapt their behavior based on the locations of mobile devices. For many applications, it is critical that location-dependent...
Functions which map n-bits to m-bits are important cryptographic sub-primitives in the design of additive stream ciphers. We construct highly nonlinear t-resilient such functions (...
We address the issue of encrypting data in local storage using a key that is derived from the user's password. The typical solution in use today is to derive the key from the...
Abstract. Provable security is a very nice property for cryptographic protocols. Unfortunately, in many cases, this is at the cost of a considerable loss in terms of efficiency. Mo...
