Prime, Order Please! Revisiting Small Subgroup and Invalid Curve Attacks on Protocols using Diffie-Hellman
formal verification symbolic model tamarin prover
2019/5/21
Diffie-Hellman groups are a widely used component in cryptographic protocols in which a shared secret is needed. These protocols are typically proven to be secure under the assumption they are impleme...
Fast Scalar Multiplication for Elliptic Curves over Prime Fields by Efficiently Computable Formulas
twisted Edwards curves Edwards curves scalar multiplication
2018/11/6
This paper addresses fast scalar multiplication for elliptic curves over finite fields. In the first part of the paper, we obtain several efficiently computable formulas for basic elliptic curves arit...
Efficient Inversion In (Pseudo-)Mersenne Prime Order Fields
finite fields inversion multiplication
2018/11/5
Efficient scalar multiplication algorithms require a single finite field inversion at the end to convert from projective to affine coordinates. This inversion consumes a significant proportion of the ...
Prime and Prejudice: Primality Testing Under Adversarial Conditions
Primality testing Miller-Rabin test Lucas test
2018/8/20
This work provides a systematic analysis of primality testing under adversarial conditions, where the numbers being tested for primality are not generated randomly, but instead provided by a possibly ...
Cost-Effective Private Linear Key Agreement With Adaptive CCA Security from Prime Order Multilinear Maps and Tracing Traitors
broadcast encryption private linear key agreement traitor tracing
2018/5/28
Private linear key agreement (PLKA) enables a group of users to agree upon a common session key in a broadcast encryption (BE) scenario, while traitor tracing (TT) system allows a tracer to identify c...
Threshold Properties of Prime Power Subgroups with Application to Secure Integer Comparisons
RSA homomorphic encryption homomorphic threshold
2018/3/5
In contrast to related work which encrypts and acts on each bit of the input separately, our protocol compares multiple input bits simultaneously within a single ciphertext. Compared to the related pr...
ABE with Tag Made Easy: Concise Framework and New Instantiations in Prime-order Groups
Attribute-based encryption Predicate encoding Prime-order bilinear group
2017/9/13
Among all existing identity-based encryption (IBE) schemes in the bilinear group, Wat-IBE proposed by Waters [CRYPTO, 2009] and JR-IBE proposed by Jutla and Roy [AsiaCrypt, 2013] are quite special. A ...
Non-Interactive Provably Secure Attestations for Arbitrary RSA Prime
RSA key generation random oracle non-interactive proof
2017/7/6
Generic non-interactive zero-knowledge (NIZK) proofs can be used to prove such properties. However, generic NIZK proofs are not practical at all. For some very specific properties, specialized proofs ...
CCA-secure Predicate Encryption from Pair Encoding in Prime Order Groups: Generic and Efficient
Predicate Encryption CCA Security Pair Encoding Scheme
2017/7/6
Attrapadung (Eurocrypt 2014) proposed a generic framework called pair encoding to simplify the design and proof of security of CPA-secure predicate encryption (PE) instantiated in composite order grou...

2017/6/27
In recent years several papers have appeared investigating the classical discrete logarithm problem for elliptic curves by means of the multivariate polynomial approach based on the celebrated summati...

The discrete logarithm problem over prime fields: the safe prime case. The Smart attack, non-canonical lifts and logarithmic derivatives.
This paper reports on the number field sieve computation of a 768-bit prime field discrete logarithm, describes the different parameter optimizations and resulting algorithmic changes compared to the ...
Attribute Based Encryption: Traitor Tracing, Revocation and Fully Security on Prime Order Groups
Traitor Tracing Revocation Ciphertext-policy Attribute Based Encryption
2016/12/15
A Ciphertext-Policy Attribute-Based Encryption (CP-ABE) allows users to specify the access policies without having to know the identities of users. In this paper, we contribute by proposing an ABE sch...
