Abstract :
Lu and Lee´s cryptosystem has been proved to be insecure, and Adiga and Shankar´s modified Lu-Lee system has been threatened by Kannan´s algorithm. Here, the authors propose other modified Lu-Lee cryptosystems which use nonlinear encryption functions. The new system seem seem to be secure.
