Electronic record authentication uses digital signatures, asymmetric cryptography and hash functions, with verification through the subscriber's public key.

Authentication of electronic records permits a subscriber to authenticate an electronic record by affixing a digital signature. Authentication is effected through an asymmetric cryptographic system and hash function. The same electronic record produces the same hash result, while reconstruction of the original record from that result and identical results from two electronic records must be computationally infeasible. Verification may be performed using the subscriber's public key; the private and public keys are unique to the subscriber and constitute a functioning key pair.
