A Conditional Privacy-Preserving Short Signature Scheme for Industrial Internet of Things
Article Information
Abstract
Securely transmitting a large amount of data in a short time is a serious challenge in today's digital age. Cryptographic primitives can significantly alleviate this problem. The invention of digital signatures represents a major advance in this area. The Certificateless Aggregate Signature (CLAS) scheme is a cryptographic primitive that greatly reduces the computation cost by aggregating several signatures into a single short signature. However, the costs of aggregate signatures have not been reduced to the desired extent. In this paper, we propose a certificateless aggregate signature scheme that requires only two bilinear pairing operations to verify both a single signature and an aggregate signature, regardless of the number of signers. This makes the scheme highly suitable for low-cost IoT applications. In this scheme, we also present a Type I attack on Horng et al.'s scheme and provide an improved version.
