Latest Patents

One of his latest patents is titled "Token binding using trust module protected keys." This invention provides a method for binding a security token to a client token binder, such as a trusted platform module. The bound security token can only be utilized on the client from which it was obtained. A secret binding key (k) is established between the client and a Security Token Service (STS). The client derives a key (k) from k, signs a security token request with k, and instructs the STS to bind the requested security token to k. The STS validates the request by deriving k using a client-provided nonce and k to create a message authentication code (MAC) and compare the MAC values. If validated, the STS generates a response that includes the requested security token, derives two keys from k—one for signing the response and another for encrypting it—and sends the response to the client. Only a device that possesses k is enabled to use the bound security token, thereby providing increased security.

Another notable patent is "Proof of possession for web browser cookie based security tokens." In this embodiment, a user device may access a network service using a secure cookie. A high trust process creates an authentication proof using a secure key. This high trust process provides a browsing token and the authentication proof to a low trust process, which then sends it to an authentication service.
