The authors stated that “[u]nforgeable digital signatures are needed” to protect against a message being “later repudiated by either the transmitter or sender.” As public key technology progressed in the late 1970s and into the 1980s, nonrepudiation became one of four main features touted by proponents of the technology. Along with confidentiality (provided by encryption), authentication, and data integrity, nonrepudiation via digital signature schemes was hailed as the enabling technology for electronic commerce.
In the late 1980s, the concept of nonrepudiation began making ...
