Study on RSA Based Identity Authentication Algorithm and Application in Wireless Controlling System of Aids to Navigation

摘要

This paper studies the safe wireless communication of controlling instructions in system of aids to navigation. RSA based authentication algorithm is employed, and Euclid addition chains are used to compute the modular exponentiation of RSA, transforming the shortest addition chains of a large number e into those of three smaller numbers a, b and c, which meets e=a×b+c. Experiment results show that the Euclid addition chains need much less time and space to create. In the case of wireless communication with authentication, controlling instructions can be transmitted safely and accurately, and it is hard for malicious users to control the intelligent lights directly. This is of great significance for navigation trades.
