  • Secure Functionality:
  • Authentication of users, authentication & attestation of the CSP to entities, data authentication & non-repudiation including time stamps, encryption & decryption of data, trusted channel including mutual authentication of the communicating entities, encryption with integrity protection and origin authentication, decryption with integrity and origin verification.
  • Management of cryptographic keys with security attributes including key generation, key derivation and key agreement, internal storage of keys, import and export of keys with protection of their confidentiality and integrity, key attestation.
  • Generation of random bits which may be used for security services outside the CSP.
  • Secure signature counter (32 bit counter limited to 51+ million operations,
  • Time related services such as certificate validity check and secure time stamping.
