A Secure and Efficient Voice Authentication Framework Based on Frequency Shift Keying Modulation and Modified Optimized RSA Encryption

The work introduces a leading-edge system of scrutiny of the identities of users based on their voices, combining FSK modulation with the versions of MORSA encryption with improvements to the security system. Enhancing the provision of secure message delivery across chaotic networks of communications by modulating FSK. The ability to distinguish the separate vocal characteristics from the bandwidths has the benefit of increasing resilience to any disturbances. At the same time, the MORSA technique improves the security of encryption with a composite number RSA configuration, which increases the performance and strengthens the decryption attacks. Combining the two systems will result in an integrated security approach, in which the privacy of data accuracy protection is offered simultaneously in the identity verification processes. As empirical evaluations reveal, the proposed solution possesses excellent validation accuracy and negligible processing time, which is the reason why it can be considered an appealing choice when it comes to immediate data processing in common critical communications systems.
