WebThe primary purpose of a PKI is to manage digital certificates. They are a powerful security tool that supports numerous operations. The use of a Public Key Infrastructure (PKI) by an organization demonstrates a dedication to the security of the network and the effectiveness of public key encryption and certificate-based networks. WebPKI (public key infrastructure): A public key infrastructure (PKI) supports the distribution and identification of public encryption keys , enabling users and computers to both securely exchange data over networks such as the Internet and verify the identity of the other party.
Before the mid-1970s, all cipher systems used symmetric key algorithms, in which the same cryptographic key is used with the underlying algorithm by both the sender and the recipient, who must both keep it secret. Of necessity, the key in every such system had to be exchanged between the communicating parties in some secure way prior to any use of the system – for instance, via a secure channel. This requirement is never trivial and very rapidly becomes unmanageable as th… WebPublic Key Infrastructure (PKI) PKI provides assurance of public key.
