Efficient transmission of PKI certificates using elliptic curve cryptography and its variants

: The demand for wireless networks is increasing rapidly and it becomes essential to design existing Public-Key Infrastructure (PKI) useful for wireless devices. A PKI is a set of procedures needed to create, distribute and revoke digital certificates. PKI is an arrangement that binds public keys with respective user identities by means of a Certificate Authority (CA). The user identity must be unique within each CA domain. The third-party Validation Authority (VA) can provide this information on behalf of CA. The binding is established through the registration and issuance process which is carried out by software at a CA or under human supervision. Elliptic Curve Cryptography (ECC) is proved to be the best suited one for resource constrained applications. This paper compares the two PKI Algorithms ECC and Rivest-Shamir-Adleman (RSA). It is found that ECC-based signatures on a certificate are smaller and faster to create; and the public key that the certificate holds is smaller as well...
