Abstract:

In this paper, an approach to design a real-time cryptography system for transferring vital signals is presented. The cryptography requirement is dictated by patient privacy. The system is divided into five main parts, namely symmetric encryption algorithms, key-exchange algorithm, hash function, communication protocol and display. The implemented algorithms are chosen based on parameters such as encryption speed, level of security and complexity. The key-exchange algorithm presented in this paper is based on the Diffie-Hellman key exchange protocol while SHA-1 hash function has been used as a component of authentication. A private message combined with Diffie-Hellman key is hashed to authenticate both parties. Finally, a communication protocol has been proposed for the system.
