Summary: This paper introduces an efficient identity-based signature scheme that is proved secure under the standard model. The scheme's security is reduced to the well-known computational Diffie-Hellman assumption, and it outperforms related schemes in terms of computation cost for signing and verification.

Summary: Internet of things (IoT) devices are used to provide services and minimize data storage and processing by gathering data and sending it to cloud servers. The proposed provably secure certificateless signature (PSCLS) scheme addresses the issues of computational overhead and adversarial attacks faced by current certificateless signature schemes in the industrial IoT network.

Summary: This paper examines the stability issue caused by partially deployed secure BGP mechanisms. By analyzing the characteristics of topology and routing strategies, we find that casually deploying security mechanisms may result in BGP oscillation problems, affecting the security and quality of inter-domain communications. To avoid oscillation issues, we propose deployment guidelines.

Summary: BGP is a fundamental infrastructure in the current Internet, but lacks security considerations and deterministic routing support for future applications. To address this, a novel BGP management architecture called BGPChain, based on blockchain technology, is proposed to establish a secure, smart, and agile routing infrastructure for the future Internet.

Summary: The researchers propose a provable secure arbitrator quantum signature (AQS) scheme based on the non-orthogonal entangled-triple sequence. Theoretical security proof, non-cloning theorem, and non-repudiation analysis are presented to ensure the security of the AQS. Compared to similar schemes, this proposal has better merits in security and efficiency.

Summary: This paper proposes an authentication protocol with a full aggregation signature to secure smart city applications. By using a certificate-less aggregate signature (CLAS), message authentication, user anonymity, constant signature size, unlinkability, and resistance to replay attacks can be achieved. Performance evaluation results show that the proposed CLAS performs better than existing relevant schemes.

Summary: An aggregate signature is a cost-effective digital signature method that reduces storage costs and bandwidth consumption, making it attractive for various blockchain applications. We propose a pairing-free aggregate signature scheme based on ECDSA, which is computationally efficient and does not require additional parameters and costs for signature aggregation and verification in blockchain applications.
