Pki-based Technology To Build Enterprise Unified Authentication Platform

PKI, as the abbreviation for Public Key Infrastructure, means the fundamental infrastructure established by the theory and technology of public key to provide the information security service. In the Public Key scheme, the most extensively applied encryption scheme at present, the key for encryption is different from the key for decryption, which means the sender sends the encrypted data via the public key of the receiver while the receiver decrypts the data via his own private key. The public key scheme ensures not only the security of data but also the undeniable data. Now the public key scheme is widely used in CA (Certificate Authority), digital signature, key exchange and other fields.This paper, from the aspect of enterprise practices, designs the platform of PKI for the application system of the entire enterprise, analysis the practices of PKI and adopts the PKI fundamental platform as the secured infrastructure. For the purpose of this paper, the writer structures the Enterprise Uniform Authentication Platform based on PKI scheme and explores the details for integrating the current applications of the enterprise.It could be concluded that the research of PKI scheme in this paper shall provide a reference for the internal security structure of an enterprise and shall be useful for the enterprises planning or proposing to do e-commerce.
