Abstract
Techniques for provisioning a key server to facilitate secure communications between a web server and a client by providing the client with a first data structure including information on how the web server may obtain a target symmetric key are presented. The techniques can include: provisioning the key server with a second data structure including information on how the key server may generate the first data structure; receiving a request on behalf of a web server for a third data structure comprising information on how the client may obtain the first data structure from the key server; and obtaining the third data structure, such that the third data structure is published in association with an identification of the web server, and such that the client uses the third data structure to obtain the first data structure and uses the first data structure to communicate with the web server.
