In this work we apply the systematic approach of game-based security specifications and proofs by reductions, to the design and evaluation of public key infrastructure (PKI) schemes. The importance of...
A multisignature scheme allows a group of signers to collaboratively sign a message, creating a single signature that convinces a verifier that every individual signer approved the message. The increa...
Secure messaging apps have enjoyed huge uptake, and with the headline figure of one billion active WhatsApp users there has been a corresponding burst of academic research on the topic. One might ther...
We devise the first weak multilinear map model for CLT13 multilinear maps (Coron et al., CRYPTO 2013) that captures all known classical polynomial-time attacks on the maps. We then show important appl...
Many modern block ciphers are constructed based on the paradigm of substitution-permutation networks (SPNs). But, somewhat surprisingly---especially in comparison with Feistel networks, which have bee...
Cogliati et al. introduced the tweakable Even-Mansour cipher constructed from a single permutation and an almost-XOR-universal (AXU) family of hash functions with tweak and key schedule. Most of previ...
Lattice-based cryptography has been received significant attention in the past decade. It has attractive properties such as being a major post-quantum cryptography candidate, enjoying worst-case to a...
Bent functions shows some vital properties among all combinatorial objects. Its links in combinatorics, cryptography and coding theory attract the scientific community to construct new class of bent f...
We provide the first provable-security analysis of the Intel Secure Key hardware RNG (ISK-RNG), versions of which have appeared in Intel processors since late 2011. To model the ISKRNG, we generaliz...
The article proposes an Online/Off-line Ring Signature Scheme in random oracle model.Security of the scheme relies on both Computational Diffie-Hellman and k-CAA problems. The proposed scheme is pro...
The iterated Even-Mansour cipher is a construction of a block cipher from r public permutations P1,…,Pr which abstracts in a generic way the structure of key-alternating ciphers. The indistinguishabil...
QUIC is a secure transport protocol developed by Google and implemented in Chrome in 2013, currently representing one of the most promising solutions to decreasing latency while intending to provide...
This paper analyses provable security proofs, using the EDL signature scheme as its case study, and interprets their bene fits and drawbacks when applied to the real world. Provable security has been...
We show that public-key bit encryption schemes which support weak (i.e., compact) homomorphic evaluation of any sufficiently "sensitive" collection of functions cannot be proved message indistinguisha...
This paper provides the provable-security treatment of path vector routing protocols. We first design a security definition for routing path vector protocols by studying, generalizing, and formalizing...
