Establishment of Public Key Infrastructure for Digital Signatures

Abstract

Open Security Socket Layer (SSL) is a cryptographic library that uses appropriate security systems such as encryption, digital signatures, digital certificates, public/private key pairs, non-repudiation and time-stamping to participate in the cryptography. A Public Key Infrastructure (PKI) comprises a system of certificates, certificate authorities, subjects, relying partners, registration authorities and key repositories that provide for safe and reliable communications. In this paper, open SSL has been implemented to provide an alternative to the Transmission Control Protocol (TCP). Open SSL is a real time protocol in which the parties negotiate interactively to authenticate each other and establish a session key, in contrast to a protocol such as email in which one party prepares a message encrypt and send, that can later be decrypted and authenticated by the intended recipient.
