Data Origin Authentication
Data Origin Authentication: A process or protocol ensuring that the content of an electronic message or document is provided by the claimed sender (the origin) and has not been altered in transit. It’s crucial for secure communications in networks, verifying that the data received has not been tampered with and actually comes from the purported […]
Credential Management
Credential Management: The process of creating, storing, managing, and updating user credentials such as usernames, passwords, and personal identification numbers (PINs), as well as digital certificates and keys. Effective credential management is crucial in maintaining security and controlling access to sensitive systems and data. It encompasses practices such as enforcing password complexity requirements, implementing regular […]
Credential Service Provider (CSP)
Credential Service Provider (CSP): An entity that issues digital credentials for the purpose of authenticating users to a network or service. A CSP validates the identity of individuals or entities and then issues credentials such as usernames, passwords, tokens, certificates, or biometric data, enabling them to prove their identity electronically.

Cross-certification
Cross-certification: A process where two or more certification authorities (CA) mutually exchange and recognize their certificates. This is used to establish trust between different certification authorities and to allow them to exchange encrypted information securely. Examples of this include a CA in the US recognizing a CA in Europe or a government CA recognizing a […]
Crossover Error Rate (CER)
Crossover Error Rate (CER): In biometrics, the Crossover Error Rate (CER) is a critical performance metric that represents the point at which the False Acceptance Rate (FAR), the measure of the likelihood that the system incorrectly grants access to an unauthorized user, equals the False Rejection Rate (FRR), the measure of the likelihood of the […]
