Cryptographic log-on (CLO)
is a process that uses Common Access Cards
(CAC) and embedded Public Key Infrastructure
(PKI) certificates to authenticate a user's identification to a workstation and network. It replaces the username and passwords for identifying and authenticating users. To log-on cryptographically to a CLO-enabled workstation, users simply insert their CAC into their workstation’s CAC reader and provide their Personal Identification Number
The Navy/Marine Corps Intranet, among many other secure networks, uses CLO.
