On Hashing with Tweakable Ciphers
Cryptographic hash functions are often built on block ciphers in order to reduce the security of the hash to that of the cipher, and to minimize the hardware size. Proven secure co...

On the Key Exposure Problem in Chameleon Hashes
Chameleon signatures were introduced by Krawczyk and Rabin, being non-interactive signature schemes that provide non-transferability. However, that first construction employs a c...

On the Compressibility of NP Instances and Cryptographic Applications
We study compression that preserves the solution to an instance of a problem rather than preserving the instance itself. Our focus is on the compressibility of NP decision problem...
