An Optimistic Multi-party Fair Exchange Protocol with Reduced Trust Requirements
In 1999, Bao et al. proposed [5] a multi-party fair exchange protocol of electronic items with an offline trusted third party. In this protocol, a coalition including the initiator...

Batch Verifications with ID-Based Signatures
An identity (ID)-based signature scheme allows any pair of users to verify each other's signatures without exchanging public key certificates. With the advent of Bilinear maps...

Efficient Broadcast Encryption Using Multiple Interpolation Methods
We propose a new broadcast encryption scheme based on polynomial interpolations. Our scheme, obtained from the Naor-Pinkas scheme by partitioning the user set and interpolating mul...

Improvement on Ha-Moon Randomized Exponentiation Algorithm
Randomized recoding on the exponent of an exponentiation computation into a signed-digit representation has been a well known countermeasure against some side-channel attacks. Howe...

Algebraic Attacks on Combiners with Memory and Several Outputs
Algebraic attacks on stream ciphers [14] recover the key by solving an overdefined system of multivariate equations. Such attacks can break several interesting cases of LFSR-based ...
