Country Signing Certification Authority (CSCA)

‚ÄčEach State issuing an ePassport establishes a single Country Signing Certification Authority (CSCA) as its national trust point in the context of ePassports. CSCA certificates are generated and are generally used for periods of three to five years. CSCA certificates issue the Document Signer Certificates that are then used to create the digital signatures on ePassports. The Document Signer must be validated against the CSCA to validate the digital signature.
