Elliptic Curve Cryptography (ECC) is the cornerstone of data security in the current cloud encryption systems, offering strong defence against unauthorized access. Nevertheless, ECC has drawbacks such as complex key management, difficulties with scaling, problems with interoperability, and Vulnerability to quantum assaults. The Secure Multi- party (SM2) signature method is a transformative solution that we present in our suggested system. By streamlining essential management procedures, SM2 reduces computational overhead and improves system performance in order to overcome these constraints. Additionally, SM2 enhances system functionality and interoperability, enabling smooth interaction with various cloud architectures. Crucially, SM2 provides defence against quantum attacks, guaranteeing long- term data security in encryption systems based on the cloud. Our suggested method raises the bar for cloud security by utilizing SM2, reducing current vulnerabilities and becoming ready for new problems that may arise in the quantum age.
