Non-malleable public key encryption in BRSIM/UC

István Vajda

Abstract: We propose an extension to the BRSIM/UC library of Backes, Pfitzmann and Waidner [1] with non-malleable public key encryption. We also investigate the requirement of “full randomization” of public key encryption primitives in [1], and show that additional randomization to attain word uniqueness is theoretically not justified.

Category / Keywords: cryptographic protocols / cryptanalysis, non-malleability, randomization
