Knowledge Based Authentication: Is It Quantifiable?

Knowledge based authentication (KBA) offers several advantages to traditional (conventional) forms of e-authentication like passwords, PKI and biometrics. KBA is a particularly useful tool to remotely authenticate individuals who conduct business electronically with Federal agencies or businesses infrequently. In these situations, other authentication tools such as passwords and PKI certificates can be expensive to administer for the application provider and difficult to use for the remote individual. By successfully participating in a series of KBA challenge-response queries, the identity of an individual can be established without delay. However, the complexity and interdependencies of KBA solutions used make it difficult to quantify the level of assurance that a remote user is who he claims to be. NIST is hosting this symposium to help identify standard authentication metrics that can be applied to KBA tools and solutions.

Topics to be discussed include:
  • Terminology and Components of KBA systems
  • User Requirements for KBA solutions
  • Information Source Metrics
  • Challenge-Response Metrics
  • Analysis and Scoring Metrics
  • Standard Metrics for KBA
