Use of Sparse and/or Complex Exponents in Batch Verification of Exponentiations

IEEE Transactions on Computers, 2006
Modular exponentiation in an abelian group is one of the most frequently used mathematical primitives in modern cryptography. Batch verification is an algorithm for verifying many exponentiations simultaneously. We propose two fast batch verification algorithms.

Lightweight privacy preserving data aggregation with batch verification for smart grid

Future generations computer systems, 2020
By analyzing the electricity usage data collected from users in a smart grid, the grid provider can flexibly adjust the power distribution policy. In such a setting, it is also important to ensure the confidentiality of users’ electricity usage data and ...

Lenient/Strict Batch Verification in Several Groups

2001
Batch verification is a useful tool in verifying a large number of cryptographic items all at one time. It is especially effective in verifying predicates based on modular exponentiation. In some cases, however, the items can be incorrect although they pass batch verification together. Such leniency can be eliminated by checking the domain of each item

An efficient blockchain‐based batch verification scheme for vehicular ad hoc networks

Transactions on Emerging Telecommunications Technologies, 2019
As an important branch of the Internet of Things (IoT), Vehicular Ad Hoc Networks (VANETs) have attracted wide attention from industrial and academic. Due to an opening wireless channel, the security and efficiency of VANETs have also become serious.

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 ...

An efficient identity-based signature scheme with batch verifications

Proceedings of the 1st international conference on Scalable information systems - InfoScale '06, 2006
Mapping messages or a user's identity into a point on elliptic curves is required by many pairing-based cryptographic schemes. In most of pairing-based schemes, this requirement is realized by a special hash function, MapToPoint function. However, the efficiency of the MapToPoint function is much lower than the general hash functions. In this paper, we

Research on Pairing-Based Batch Verification

2010 International Conference on Communications and Mobile Computing, 2010
Batch verification is used in cases of verifying many signatures at the same time, for it can speedup the verification of signature significantly. It is well known that if the verifier uses batch verification to verify n different signatures, he needs to pick n exponents at random.

A DAA Scheme Using Batch Proof and Verification

2010
Direct anonymous attestation (DAA) is an attractive cryptographic primitive, that is not only because it provides a balance between user authentication and privacy in an elegant way, but also because it is a part of the trusted computing technology from the Trusted Computing Group (TCG).
