A key notarization system for computer networks
Miles E. Smid · 1979
A cryptographic, Key Notarization System is proposed for computer networks to protect personal (nonshared) files, to communicate securely both on and off-line with local and remote users, to pro- tect against key substitution, to authenticate system users, to authenticate data, and to provide a digital signature capability using a nonpublic key encryption algorithm.The system is imple- mented by the addition of key notarization facili- ties which give users the capability of exercising a set of commands for key management as well as for data encryption functions.Key notarization facilities perform notarization which, upon encryption, seals a key or password with the identities of the transmitter and Intended receiver.
