Enhancing Cloud Computing Data Security in Attribute-based Encryption Schemes using Cryptographic Algorithm

Attribute-Based Encryption (ABE) is a powerful cryptographic technology used in cloud computing and data security. It allows data owners to control access to encrypted data based on specific characteristics rather than individual user IDs. This makes sure that only systems that satisfy certain requirements or people, who are allowed may decode and view the data. Because of its dynamic and adaptable approach to access management, ABE is a great fit for situations with complex and dynamic access requirements. In response to the threat posed by Quantum Computing, this research study focused on developing Post-Quantum ABE schemes that maintain security while also addressing attributes like verifiability, user privacy, and revocability. A novel ABE system founded on rank metric codes has been proposed. The proposed approach is built on low rank parity check codes with a robust resistance against diverse forms of attacks with a compact key size and rapid execution time, demonstrating notable efficiency when compared to other cryptographic systems. This represents a substantial stride forward in enhancing Cloud Computing in the era of Quantum Computing.
