Digital security as a service is crucial aspect it deals with user privacy provision and secure content delivery to legitimate users. Most social media platforms utilize end-to-end encryption significant feature. However, multimedia data transmission in group communication not encrypted. One of the most important objectives for provider send desired data/service only subscriber. Broadcast appropriate cryptographic primitive solution this problem. Therefore, study devised construction called anonymous revocable identity-based broadcast that preserves messages broadcasted identity users, where even revoked users cannot extract information about user's sent data. The update key periodically non-revoked who can obtain message using decryption keys. A third-party also revoke It proven proposed semantically against IND-ID-CPA attacks efficient terms computational cost bandwidth.

To deliver applications and services required by mobile devices, cloud computing adopts computing. Cloud assists data sharing among authorized users through stored on servers. Data implies distributing resources to multiple or with the utmost security. But maintaining security while transferring in is an important challenge. In conventional algorithms, a secure environment control policies accessing for are biggest concerns deal with. handle these sensitive issues eliminate drawbacks novel technique termed Random Self-Generative Schnorr Certificateless Signcryption-based Secured Sharing (RSGSCS-SDS) proposed this work. The work improves environments. approach, initially information of registered can be server getting access permission various services. Using RSGSCS algorithm, each user, generates private public keys. Depending attributes policy, authorization user verified after receiving request. After requested transmitted form cipher text digital signature. This signature at his end, decrypted. ensures that only original content, step sharing. efficacy RSGSCS-SDS procedure evaluated key metrics like storage overhead, computational time, confidentiality rate. Experimental results demonstrate effectiveness method enhancing
