    Abstract

    The advent of cloud computing has brought about a significant change in the way data is stored and accessed, but it has also resulted in new security concerns. To address these challenges, ID-based signcryption has emerged as a cryptographic tool that can provide both encryption and authentication in a single step. The popularity of elliptic curve cryptography (ECC) has also been on the rise due to its low computational and communicational overhead. In this paper, a novel ID-based signcryption scheme that employs ECC and blockchain technology is proposed for secure data sharing in cloud environments. The proposed architecture utilizes a blockchain-based identity management, access control, and secure sharing (IAS) protocol to ensure secure transmission and access control. It tackles issues such as scalability, key management for recovery and revocation, and identity verification in a fully decentralized cloud computing environment. The proposed scheme's performance was evaluated by analysing metrics such as data access rate, computational cost, storage cost, and security authentication. The results indicate that our architecture surpasses conventional algorithms in terms of these metrics. Specifically, the proposed scheme reduces computational overhead and storage requirements while maintaining a high level of security authentication.
