Abstract
En 中文
In the current digital age, it is essential to provide security for sensitive financial data in the aftermath of rising cyberattacks. It proposes a safe method to defend financial data finished the combination of RSA-based key generation with fully homomorphic encryption (FHE). The system confirms confidentiality, data integrity, and compliance with rules through the addition of strong encryption methods, user verification, and cloud storage security. FHE proposals computation over ciphertext without decrypting, confirming the confidentiality of financial information at the time of processing. The system uses RSA-based cryptography for making secure public and private keys, while user verification and role-based admission control ensure that unauthorized users cannot access or adapt the information. Experimental results confirm the efficacy of the scheme charted here, with a neat reliability between RSA key size and key generation time, where 2048 bits use about 0.35 s and 4096 bits use about 0.55 s. FHE encryption time also varies with the encryption values, with increasing processing time linearly with the encryption values, from 0.004 s for small encryption values to 3.25 s for large values. The results also point to a data security versus processing performance trade-off and show that the proposed framework delivers a feasible, scalable, and safe means of managing financial data in cloud computing systems.
