On the Joint Security of Encryption and Signature in EMV
We provide an analysis of current and future algorithms for signature and encryption in the EMV standards in the case where a single key-pair is used for both signature and encrypt...

Optimal pairings
In this paper we introduce the concept of an optimal pairing, which by definition can be computed using only log2 r/(k) basic Miller iterations, with r the order of the groups invo...

Parameterized splitting systems for the discrete logarithm
Hoffstein and Silverman suggested the use of low Hamming weight product (LHWP) exponents to accelerate group exponentiation while maintaining the security level. With LHWP exponent...

An MSS Based on the Elliptic Curve Cryptosystem
In 2004, a multi-signature scheme (MSS) based on the elliptic curve cryptosystem is given by Chen et al. [1]. Later, Liu and Liu [6] showed that if one of the users always sends h...

Symmetric Key Image Encryption Scheme with Key Sequences Derived from Random Sequence of Cyclic Elliptic Curve Points
In this paper, cyclic elliptic curves of the form y2 + xy = x3 + ax2 + b, a, b ∈ GF(2m ) with order M is considered in the design of a Symmetric Key Image Encryption Scheme with...

Multi-authority Electronic Voting Scheme Based on Elliptic Curves
In this paper, a new multi authority electronic voting scheme based on elliptic curves is proposed. According to the proposed scheme, each voter casts the vote as a point on the e...

On the Proxy-Protected Property of Chen et al.'s Proxy Multisignature Schemes
Recently, Chen, Chung, and Huang proposed a traceable proxy multisignature scheme based on the elliptic curve cryptosystem. However, this paper shows that the original signers can ...
