Digital signature authentication ensures electronic record integrity using asymmetric cryptography and hash functions to authenticate records.
Authentication of electronic records is effected by affixing a digital signature using an asymmetric crypto system and a hash function that transforms the initial record into a reproducible hash result, where the hash function makes it computationally infeasible to reconstruct the original record from the hash or for two distinct records to yield the same hash; key definitions include addressee, originator, computer resource and electronic record, and electronic mail for the offensive-messages provision includes messages and attachments in various media.
