This paper introduces an efficient method for secure communication that combines the best aspects of two encryption techniques. It does this by taking advantage of the strengths of both symmetric and asymmetric encryption, resulting in a more secure and efficient system. Our method aims to address the challenges of key management and computational overhead while ensuring robust protection of sensitive data. The proposed scheme begins with the generation of a random symmetric key for each session, ensuring fast encryption and decryption processes. Subsequent to the generation of a symmetric key for message encryption, the key itself is encrypted utilizing an asymmetric algorithm, such as RSA. This two-step process facilitates secure key exchange between communicating parties. By leveraging this hybrid approach, the overall encryption process maintains a high level of security while achieving efficiency in message transmission. Furthermore, we introduce a dynamic key update mechanism to enhance the security of the system. This mechanism periodically updates the symmetric key used for encryption, This approach mitigates the potential for key compromise, thereby bolstering the overarching security posture of the communication channel.
