Issues in the Implementation of PKI in UK HE/FE
Overview
This paper gives an overview of Public Key Infrastructure and looks at the issues that need to be considered when implementing PKI. It doesn’t look in detail at the technologies (PGP and X.509) involved.
PKI integrates public key cryptography, digital certificates and Certificate Authorities with the procedures to create and manage this infrastructure. Public key cryptography, for encryption and digital signatures, involves the use of two keys. The private key is known only to the owner and is used to sign and decrypt messages. The public key can be known to anyone and is used to verify signatures and encrypt messages. It’s impossible to derive the private key from the public key. Keys may be issued or certified by a trusted third party known as a Certification Authority (CA). The existence of a CA helps to deal with problems of trust when encryption is used in the transmission of information between people who do not know each other, or when someone wishes to verify the digital signature of someone not known to them personally.
