Key-pair(Public key, Private key) conflict analysis using OpenSSL

Abstract The development of public-key-based technique that enables a variety of services(E-government, e-banking,e-payment, etc.) evaluated as having complete safety. On the other hand, vulnerabilities(e.g, heartbleed bug, etc.) areconstantly being discovered. In this paper, a public key infrastructure to verify the safety and reliability, the collisionrate using OpenSSL key pair was analyzed. the experiment was performed using the following procedure. Opensslwas used to create five private certification agencies, and each of the private certificate authority certificates to create2 million, generating a total of 10 million by the certificate of the key pair conflicts analysis. The results revealed35,000 in 1 million, 0.35% chance of a public key, a private key conflict occurred. This is sufficient in variousfields(E-payment, Security Server, etc.). A future public-key-based technique to remove the threat of a random number generator, large minority issues, in-depth study of selection will be needed.
