The purpose of this article is to present,illustrate and to put in evidence a new side-
channel attack on RSA cryptosystem based on the generation of prime numbers. The
vulnerability of the cryptosystem is spotted during the execution of the key generation step.The probability of success of the attack is around 10-15% in the case of realistic parameters
