Abstract:
The Internet of Things (IoT) is a new technological innovation, which makes things intelligent and our life more convenient. To ensure secure communication between smart objects in the IoT, certificateless signature is a feasible cryptographic tool to provide data integrity and identity authentication, which eliminates the cumbersome certificate management in the certificate-based signature system, as well as the key escrow problem in the identity-based cryptosystem. However, most of the existing certificateless signature schemes are not all secure to resist various attacks, such as public key replacement attacks or malicious-but-passive key-generation-center attacks. Besides, due to the limited storage and processing capabilities of these smart things, they are unable to meet the real-time demands of the IoT completely. This paper first analyzes Jias scheme.
