Network security via private-key certificates
D. D. Davis, Ralph R. Swick · ACM SIGOPS Operating Systems Review · 1990
We present some practical security protocols that use private-key encryption in the public-key style. Our system combines a new notion of private-key certificates , a simple key-translation protocol, and key-distribution. These certificates can be administered and used much as public-key certificates are, so that users can communicate securely while sharing neither an encryption key nor a network connection.
