Batch Verification for Certificateless Signature Schemes

2009 International Conference on Computational Intelligence and Security, 2009
Batch verification is a practical and significant technique which is very useful for greatly reducing the computational cost of verifying many signatures simultaneously. This technique is very attractive for authentications in computation-limited applications such as sensor network and banking service.

Cryptanalysis schemes against batch verification signature

2009 Chinese Control and Decision Conference, 2009
Batch verification signature is an efficient signature to generate and verify signatures for a batch of message in a single protocol. In the paper, analyses were made on the basic principles of batch verification signature, as to the security problems of present batch verification signature schemes; we presented an improved batch verification signature

Batch Verifications with ID-Based Signatures

2005
An identity (ID)-based signature scheme allows any pair of users to verify each other’s signatures without exchanging public key certificates. With the advent of Bilinear maps, several ID-based signatures based on the discrete logarithm problem have been proposed. While these signatures have an advantage in the fact that the system secret can be shared

Effient Electronic Cash Using Batch Signatures

1999
All known anonymous electronic cash protocols are inefficient compared to other electronic payment protocols. This is because much of the complexity of the protocols is devoted to ensuring the anonymity of the consumer. This problem is addressed with an extension of Brands' electronic cash payment protocol using batch cryptography.

Batch Blind Signatures on Elliptic Curves

2015
Blind signature is a fundamental tool in electronic cash. In most existing blind signature schemes, both the signer and the verifier need to take expensive modular exponentiations. This situation is deteriorated in significant monetary transactions in which a large number of (multi-)exponentiations need to be calculated. This paper proposes batch blind

Constructing efficient and secure batch signature schemes

Journal of Military Science and Technology, 2021
In ordinary signature schemes, such as RSA, DSA, ECDSA, the signing process is performed only for a single message. Due to performance issues, in some contexts, the above solutions will become unsuitable if a party needs to sign multiple messages simultaneously. For example, in the authenticated key exchange protocols based on signatures between client

Secure Certificateless Signature Scheme Supporting Batch Verification

2013 Eighth Asia Joint Conference on Information Security, 2013
In this paper, we propose a secure certificate less signature scheme supporting batch verification, which makes it possible for a verifier to verify a set of signatures more efficiently than verifying them one by one. In our proposed scheme, it is impossible for PKG to produce a signature which is indistinguishable from any signature produced by a user.

Batch verification of Digital Signatures: Approaches and challenges

Journal of Information Security and Applications, 2017
Abstract Digital Signatures can be considered analogous to an ordinary handwritten signature for signing messages in the Digital world. Digital signature must be unique and exclusive for each signer. Multiple Digital Signatures signed by either single or multiple signers can be verified at once through Batch Verification.

Trade-off between signature aggregation and batch verification

2013 36th International Conference on Telecommunications and Signal Processing (TSP), 2013
The paper deals with optimization techniques of digital signatures applied in information and communication architectures. The techniques called the signature aggregation and batch verification cause two contrary benefits: small computational overhead or small communication overhead, shorter chain of signatures or faster verification process ...

Efficient Identification of Bad Signatures in RSA-Type Batch Signature

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2006
As the use of electronic voting systems and e-commerce systems increases, the efficient batch verification of digital signatures becomes more and more important. In this paper, we first propose a new method to identify bad signatures in batches efficiently for the case when the batch contains one bad signature. The method can find out the bad signature
