Abstract :
The two models of traditional cryptography (symmetric encryption and asymmetric encryption) are confronted, in addition to the difficulty in creating credible keys of encoding/decoding, to the problem of distributing keys with perfect security. We present in this article results of a simulation of successful eavesdropping when exchanging keys with RSA algorithm. A solution to this problem is proposed by quantum physics. In this case, the security of the exchanged keys is not based on algorithmic complexity but rather on the laws of the quantum physics. Many quantum protocols are elaborated to exchange keys with unconditionally security. We are interested here in simulation of the protocol BB84 which the security is unconditional due to Heisenberg´s uncertainty principle.
