Given its asymmetric nature, PKI is used in many parts of the world for higher assurance use cases.

In PKI authentication, a private encryption key is used, which is non-transferrable when stored in a hardware token. While OTP authentication, for example with OTP apps, may provide sufficient protection for most enterprise use cases, verticals that require higher levels of assurance, such as e-government and e-health, may be mandated to use PKI security by law. For more details, watch The Science of Secrecy videos by Simon Singh.) If there’s a mathematical correlation, or ‘match,’ between the signed challenge and your public encryption key (known to your network server), then authentication is successful and you’re granted access to the network. When authenticating to your enterprise network server, for example, the server issues a numeric ‘challenge.’ That challenge is signed using your private encryption key. Hardware PKI certificate-based tokens, such as smart cards and USB tokens are designed to store your secret private encryption key securely. PKI authentication is a form of ‘asymmetric’ authentication as it relies on a pair of dissimilar encryption keys-namely, a private encryption key and a public encryption key. If the OTP generated by your token matches the OTP generated by the authentication server, then authentication is successful and you’re granted access. One time passwords (OTPs) are a form of ‘symmetric’ authentication, where a one-time password is simultaneously generated in two places-on the authentication server and on the hardware token or software token in the user’s possession. What is the difference, and which should you use for your organization? One-Time Passwords Two factor authentication methods are based on a variety of technologies, most prominently one time passwords (OTPs) and Public key infrastructure (PKI).
