摘要
As security is essential in communications through electronic networks, development of structures providing high levels of security is needed. Public Key Infrastructure (PKI) is a way of providing security measures by implementing the means of key pairs among users. In this paper, an overview of the public key infrastructure is discussed that includes various components and operation, some well known PKIs and their comparisons. Also we discuss current implementations, risk and challenges of PKIs.
