This research paper aims at analyzing the impact of exploiting the parallelism available in two common Elliptic Curve Cryptography (ECC) projective forms on speed and cost factors, assuming point-multiplication is implemented using the m-ary algorithm instead of the popular binary algorithm. Point-multiplication is implemented using scalable multipliers in(More)
This paper presents two new multi-signature schemes which aim at providing data authenticity, integrity, and non-repudiation. The proposed signing/verifying schemes are extensions of standardized algorithms, such as DSA (Digital Signature Algorithm) and ECDSA (Elliptic Curve DSA) algorithms. These schemes are faster than repeated individual signature (RDSA)(More)
