We initiate the cryptographic study of order-preserving symmetric encryption (OPE), a primitive suggested in the database community by Agrawal et al. (SIGMOD '04) for allowin...

Despite the recent advances in the theory underlying obfuscation, there still is a need to evaluate the quality of practical obfuscating transformations more quickly and easily. T...

It is sometimes argued (as in [6]) that finding meaningful hash collisions might prove difficult. We show that at least one of the arguments involved is wrong, by showing that for...
We present a single-database private information retrieval (PIR) scheme with communication complexity O(k+d), where k ≥ log n is a security parameter that depends on the database...
The implementation of a standard PKI in a mobile ad hoc network (MANET) is not practical for several reasons: (1) lack of a fixed infrastructure; (2) a centralized certification au...
