The key management of public key defines two aspects first one is the distribution of public key and the second one is the use of public key to distribute secret keys for encryption. In this paper, the authors are presenting the public key authentication framework. The distribution of public key can be done by many ways but in this paper they are presenting the two schemes known as the Public Key Authority without certification authority (PKAw CA) and public key authority with Certification Authority (CA) or certification authority. In this paper, they have compared both the schemes with respect to security, availability and their support and prepare a comparison chart for them.
