Universal Re-encryption allows El-Gamal ciphertexts to be re-encrypted without knowledge of their corresponding public keys. This has made it an enticing building block for anonymo...
A weak pseudorandom function (wPRF) is a cryptographic primitive similar to ? but weaker than ? a pseudorandom function: for wPRFs one only requires that the output is pseudorandom...
Abstract. Even and Mansour [EM97] proposed a block cipher construction that takes a publicly computable random permutation oracle P and XORs different keys prior to and after appl...
Power analysis has shown to be successful in breaking symmetric cryptographic algorithms implemented on low resource devices. Prompted by the breaking of many protected implementat...
