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...
Okamoto Beats Schnorr: On the Provable Security of Multi-Signatures
Provable Security Multi-Signatures
2018/5/11
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...
Mind the Gap: Where Provable Security and Real-World Messaging Don't Quite Meet
cryptographic protocols messaging implementation position
2017/10/10
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...
New Multilinear Maps from CLT13 with Provable Security Against Zeroizing Attacks
multilinear maps obfuscation CLT13
2017/9/28
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...
On the Provable Security of the Tweakable Even-Mansour Cipher Against Multi-Key and Related-Key Attacks
Tweakable Even-Mansour almost-XOR-universal hash functions multi-key attack
2016/12/29
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...

A Provable Security Analysis of Intel's Secure Key RNG
random number generator entropy extraction provable security
2016/1/8
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...
Online/Off-line Ring Signature Scheme with Provable Security

On the Provable Security of the Iterated Even-Mansour Cipher against Related-Key and Chosen-Key Attacks
block cipher ideal cipher related-key attacks
2016/1/4
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...
