Public key infrastructure (PKI) is a two-key, asymmetric cryptosystem that affords different IT systems high-level information confidentiality and confidence.
This is how it works: the sender of confidential information requests the recipient entity’s public key, which is not secret, before sending the information. The recipient can only decrypt the information using its private key.
The recipient’s identity is assured through a digital certificate issued by a third-party certificate authority (CA) – such as LAWtrust – that issues, revokes and distributes digital certificates.
