Access control is the fundamental security service in ad hoc groups. It is needed not only to prevent unauthorized entities from joining the group, but also to bootstrap other secu...
We develop a method for generating shared, secret, safe primes applicable to use in threshold RSA signature schemes such as the one developed by Shoup. We would like a scheme usabl...
An identity-based signcryption scheme with (t, n) shared unsigncryption is proposed, which is the integration of the signcryption scheme, the (t, n) threshold scheme and zero know...
