staff is mostly software developers and a small number of administrative personnel. The client has decided that it would be in their best interest to use a public key infrastructure (PKI) to provide a framework that facilitates confidentiality, integrity, authentication, and nonrepudiation. Fundamentals of PKI. Public Key Infrastructure is a security architecture created to provide a high level of confidence for exchanging information over the internet that has become more and more insecure

underlying concept of PKI is public key cryptography--the most widely used technology used in authenticating senders or encrypting messages in the Internet. In order to appreciate the necessity of public key cryptography, it is important to understand the limitations of traditional cryptography, which usually involves creating and sharing a secret key to encrypt and decrypt messages. Using traditional cryptography, communications over the Internet may easily be decrypted if the key is intercepted. The PKI

A root certificate is the top most certificate in the highest position, the private key of which is used to sign other certificates. All certificates immediately below the root certificate inherit the trustworthiness of the root certificate and a signature by a root certificate is basically analogous to notarizing. Using a PKI would establish and maintain a trustworthy networking environment by providing key and certificate management services that enable encryption and digital signature capabilities
