Group Signature Schemes with Membership Revocation for Large Groups
Group signature schemes with membership revocation have been intensively researched. However, signing and/or verification of some existing schemes have computational costs of O(R)...

A Complete Divisor Class Halving Algorithm for Hyperelliptic Curve Cryptosystems of Genus Two
We deal with a divisor class halving algorithm on hyperelliptic curve cryptosystems (HECC), which can be used for scalar multiplication, instead of a doubling algorithm. It is not ...

Two Improved Partially Blind Signature Schemes from Bilinear Pairings
A blind signature scheme is a protocol for obtaining a digital signature from a signer, but the signer can neither learn the messages he/she sign nor the signatures the recipients ...

Tunable Balancing of RSA
We propose a key generation method for RSA moduli which allows the cost of the public operations (encryption/verifying) and the private operations (decryption/signing) to be balanc...
