A Combination Multi-signature Scheme

2009 International Conference on Networking and Digital Society, 2009
The concept of the multi-signature was first proposed by Itakura and Nakamura, in which multiple signers can cooperate to sign the same message and any verifier can verify the validity of the multi-signature. After that, a lot of multi-signature schemes were proposed, but almost all of the multi-signature schemes are either sequence multi-signature or ...

A Comment on a Multi-Signature Scheme

2006
We will show that the structured ElGamal-type multisignature scheme due to Burmester et al. be not secure if the adversary attacks key generation.

Dynamic multi-signatures for secure autonomous agents

12th International Workshop on Database and Expert Systems Applications, 2001
Mobile agents are an appealing technology for distributed applications in open networks. A major problem is the asymmetric relation of mobile agents and their execution environment in matters of security. The security concerns are even greater in the case where agents are executed autonomously in multiple hosts, and in particular when the environment ...

Independent verification of proxy multi-signature scheme

International Journal of Computational Science and Engineering, 2014
Privacy has become one of the most important human rights of the modern age. To our knowledge, in order to verify the validity of the proxy multi-signature, the verifier needs to get all the original signers' public keys together. Obviously, the verification would leak the relationships between the proxy signer and the original signers.

Efficient multi-signature schemes for cooperating entities

1994
Sharing signature power may be required in many occasions. Moreover a multisigning operation may be required to be performed simultaneously (in some sense) by all the involved cosigning parties.

Design of Multi-signature Scheme in Wireless Networks

6th IEEE/ACIS International Conference on Computer and Information Science (ICIS 2007), 2007
This paper describes the design of a new multi- signature scheme based on elliptic curve cryptosystems(ECC) for securing wireless networks. The scheme utilizes the improved elliptic curve digital signature algorithm(ECDSA) to design the multi- signature.

MuSig2: Simple Two-Round Schnorr Multi-signatures

2021
Multi-signatures enable a group of signers to produce a joint signature on a joint message. Recently, Drijvers et al. (S&P’19) showed that all thus far proposed two-round multi-signature schemes in the pure DL setting (without pairings) are insecure under concurrent signing sessions. While Drijvers et al.

A Trustless GQ Multi-signature Scheme with Identifiable Abort

2021
Guillou-Quisquater (GQ) signature is an efficient RSA-based digital signature scheme amongst the most famous Fiat-Shamir follow-ons owing to its good simplicity. However, there exist two bottlenecks for GQ hindering its application in industry or academia: the RSA trapdoor \(n=pq\) in the key generation phase and its high bandwidth caused by the ...

A Secure Anonymous Proxy Multi-signature Scheme

Proceedings of the 11th International Conference on Security and Cryptography, 2014
Proxy signature scheme enables a signer to delegate its signing rights to any other user, called the proxy signer, to produce a signature on its behalf. In a proxy multi-signature scheme, the proxy signer can produce one single signature on behalf of multiple original signers.

ECDLP Based Proxy Multi-signature Scheme

2012
A Proxy signature scheme enables a proxy signer to sign a message on behalf of the original signer. In this paper, we propose efficient and secure Proxy multi-signature scheme based on elliptic curve cryptosystem. Our scheme satisfy all the proxy requirements and require only elliptic curve multiplication and elliptic curve addition which needs less ...
