Users' required bandwidth can be decreased and data redundancies in cloud storage can be effectively eliminated using data deduplication. However, because they have trouble disclosing information, the majority of earlier systems that relied on the assistance of a trusted key server (KS) are weak and constrained. inadequate defence against intrusions, high processing overhead, etc. Specifically, a single-point-of-failure occurs when the trusted KS fails, resulting in the system as a whole failing. insufficient protection against breaches, excessive processing overhead, etc. In particular, a single-point-of-failure happens when the system fails because the trusted KS fails. Theoretical analyses show that our SED has significant anti-attack capabilities, including resistance to collusion and brute-force attacks, and guarantees semantic security in the random oracle model. Furthermore, SED can efficiently remove data redundancies with no overhead in terms of computation, connection, or storage. SED's effectiveness and features enhance client-side usage.
