In this paper, the authors describe the security of E-passport with elliptic curves. The chip which is having the information about the passenger should occupy very less area & The chip information cannot be traceable. AS compared to other public key cryptosystems such as AES and DES elliptic curve cryptography provides greater authentication and verification security. Contactless smart cards work only with ECC because other systems require too much induction energy. The physical implementations such as power consumptions should not allow the hacker to think about the private key information.
