In the point of view security, An efficient scheme in IBE with random oracle
Rkia Aouinatou1, Mostafa Belkasmi2
Abstract: We present in these papers a scheme, which bypasses the weakness presented in the existed scheme of IBE with random oracle. We propose, a secure scheme which project into Zp contrary to elliptic
curve as with Boneh and Franklin. More, our scheme is basing in its study of simulation in the problem 4-EBDHP which is more efficient than q-BDHIP used by Skai Kasarah. We provide the prove of security of our scheme and we show its efficiency by comparison with the scheme declared
above. Even if it we have a little cost in complexity, but as in the field cryptography we are more interested to the security, this makes our proposition more efficient.
Category / Keywords: public-key cryptography / Random Oracle, IBE, Security, 4-EBDHP, q-BDHIP, projection into elliptic curve.
