Enhanced Target Collision Resistance (eTCR) property for a hash function was put forth by Halevi and Krawczyk in Crypto 2006, in conjunction with the randomized hashing mode that i...
We answer the question of Reyhanitabar et al. from FSE’09 of constructing a domain extension scheme for enhanced target collisionresistant (eTCR) hash functions with sublinear ke...
We present a new non-interactive message authentication protocol in manual channel model (NIMAP, for short) using the weakest assumption on the manual channel (i.e. assuming the st...

We revisit the problem of constructing a protocol for performing authenticated encryption with associated data (AEAD). A technique is described which combines a collision resistant...
Abstract. Digital signatures are often proven to be secure in the random oracle model while hash functions deviate more and more from this idealization. Liskov proposed to model a ...
