Optimal security reductions for unique signatures (Coron, Eurocrypt 2002) and their generalization, i.e., efficiently re-randomizable signatures (Hofheinz et al., PKC 2012 and Baderet al., Eurocrypt 2...
At CRYPTO 2016, Cogliati and Seurin introduced the Encrypted Davies-Meyer construction, p2(p1(x)⊕x)p2(p1(x)⊕x) for two nn-bit permutations p1,p2p1,p2, and proved security up to 22n/322n/3. We present ...
We perform a concrete security treatment of digital signature schemes obtained from canonical identification schemes via the Fiat-Shamir transform. If the identification scheme is rerandomizable and...
We consider tweakable blockciphers with beyond the birthday bound security. Landecker, Shrimpton, and Terashima (CRYPTO 2012) gave the first construction with security up to O(22n/3) adversarial queri...
This paper discusses provable security of two types of cascade encryptions. The first construction \CEl, called l-cascade encryption, is obtained by sequentially composing l blockcipher calls with ind...
Waters signatures (Eurocrypt 2005) can be shown existentially unforgeable under chosen-message attacks under the assumption that the computational Diffie-Hellman problem in the underlying (pairing-fri...
