SECURE DATA SHARING IN CLOUD USING KEY AGGREGATE CRYPTOSYSTEM

Аннотация

Secure data sharing in the cloud is a critical concern to ensure the confidentiality and integrity of sensitive information stored in cloud environments. Key Aggregate Cryptosystem (KAC) is an emerging cryptographic technique that enables efficient and secure data sharing among multiple users in the cloud. This study focuses on the application of KAC for secure data sharing in cloud environments. The proposed approach utilizes a hierarchical key management scheme to generate and distribute encryption keys, allowing authorized users to access and decrypt shared data. The KAC framework ensures fine-grained access control and reduces the computational overhead associated with traditional encryption schemes. The study evaluates the security and performance aspects of the proposed approach through simulation and analysis, demonstrating its effectiveness in secure data sharing in the cloud.
