Entity authentication schemes using braid word reduction
Abstract. Artin's braid groups currently provide a promising background for cryptographical applications, since the first cryptosystems using braids were introduced in [2, 3, ...

Identity Based Group Signatures from Hierarchical Identity-Based Encryption
A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures. Our construction is based o...

Pairing-Friendly Elliptic Curves with Small Security Loss by Cheon's Algorithm
Pairing based cryptography is a new public key cryptographic scheme. An elliptic curve suitable for pairing based cryptography is called a “pairing-friendly” elliptic curve. Af...

Weak Property of Malleability in NTRUSign
A new type of signature scheme, called NTRUSign, based on solving the approximately closest vector problem in a NTRU lattice was proposed at CT-RSA’03. However no security proof ...
