Abstract. Chameleon signatures simultaneously provide the properties of nonrepudiation and non-transferability for the signed message. However, the initial constructions of chamele...
Abstract. Multi-signatures allow multiple signers to jointly authenticate a message using a single compact signature. Many applications however require the public keys of the signe...
A wireless transmitter learns of a packet loss, infers collision, only after completing the entire transmission. If the transmitter could detect the collision early (such as with ...
