Abstract. A ring signature scheme can be viewed as a group signature scheme with no anonymity revocation and with simple group setup. A linkable ring signature (LRS) scheme additio...
In the (t, n) proxy signature scheme, the signature, originally signed by a signer, can be signed by t or more proxy signers out of a proxy group of n members. Recently, an efficie...
Abstract--We consider the use of threshold signatures in adhoc and dynamic groups such as MANETs ("mobile ad-hoc networks"). We first show that known threshold RSA signat...

Non-interactive zero-knowledge proofs play an essential role in many cryptographic protocols. We suggest several NIZK proof systems based on prime order groups with a bilinear map...
