The vulnerability of cryptographic keys to exposure represents a critical risk to modern cryptographic techniques. In this paper, we present an approach to enhancing the security of encrypted communication systems through the strategic incorporation of redundancy design. As hardware costs continue to decline, deploying such redundancy becomes increasingly feasible. This approach allows for the protection of individual keys through the amalgamation of multiple redundant keys, significantly lowering the probability of security breaches. The study's findings demonstrate that the proposed scheme not only enhances the resilience of encrypted communication systems against potential eavesdropping and key exposure but also provides a scalable solution for improving overall cryptographic security.
