PKI Security Services
In cybersecurity, Public Key Infrastructures are used to protect communications between
a client’s website and the server using a series of encryptions and decryptions. PKI’s work using
a private key associated with the server, a public key in the client’s website and several
cryptographic keys (Conklin, 2015).
PKI’s offer the following security services;
a) Certificate authority
PKI systems can create and delete digital certificates as a form of maintenance to enable
clients to transmit information over public networks securely. The PKI infrastructure assigns a
digital certificate which acts as an electronic credit card which includes details such as the name
of the certificate authority, the client’s credentials and the respective expiration dates in the
online transaction process.
Authentic digital certificates issued should have a special signature from the certificateissuing authority for secure communication with the targ...
