Texas Instruments TMS Hitachi HD Users no longer had to exchange a secret key which had to always be kept secret to encrypt and decrypt messages to each other.

Instead, a public key for a message recipient could be published to the world that was tied to a secret key — Diffie called it the private-key — that the recipient would use to unlock the scrambled data. Diffie, who presented his public-private key exchange ideas at the National Computer Conference in , teamed with Stanford University professor Marty Hellman to publish the paper "New Directions in Cryptography" the same year.

Diffie says the development and elaboration of the public-private key pair is as much Hellman's work as his own. Diffie isn't wholly satisfied that he choose the word private to coin the term private key , since "privacy has so many different meanings," he points out.

But he adds that the world would do well to consider his wife, Mary Fischer, to whom he's been married 35 years, as "the Mother of Public-Key Cryptography" because she was both inspiration and support in the difficult early days of its invention. See bio of John Cocke. But in part to differentiate from other types of equipment also called gateways such as e-mail gateways , the early developers began adopting the term router.

At that point, the transition from gateway to router was officially under way. According to the Computer History Museum, Crocker wrote: "The elements of the name space are called sockets.

A socket forms one end of a connection, and a connection is fully specified by a pair of sockets. See biography of John Wilder Tukey. Mauchly and J. Presper Eckert at the University of Pennsylvania.
