A method for authenticating and negotiating security parameters among two or more network devices is disclosed. The method has a plurality of modes including a plurality of messages exchanged between the two or more network devices. In a main mode, the two or more network devices establish a secure channel and select security parameters to be used during a quick mode and a user mode. In the quick mode, the two or more computers derive a set of keys to secure data sent according to a security protocol. The optional user mode provides a means of authenticating one or more users associated with the two or more network devices. A portion of the quick mode is conducted during the main mode thereby minimizing the plurality of messages that need to be exchanged between the initiator and the responder.

Method of negotiating security parameters and authenticating users interconnected to a network

Systems and methods for performing explicit delegation with strong authentication are described herein. Systems can include one or more clients, one or more end servers, and one or more gateways intermediate or between the client and the end server. The client may include an explicit strong delegation component that is adapted to strongly authenticate the client to the gateway. The explicit strong delegation component may also explicitly delegate to the gateway a right to authenticate on behalf of the client, and to define a period of time over which the explicit delegation is valid. The system may be viewed as being self-contained, in the sense that the system need not access third-party certificate or key distribution authorities. Finally, the client controls the gateways or end servers to which the gateway may authenticate on the client's behalf.

Explicit delegation with strong authentication

A technique for establishing inspected secure communication includes establishing a first secure connection between a client device and a client-side device and a second secure connection between the client-side device and a server device. The client-side device establishes the first secure communication channel by providing a certificate impersonating the server device to the client device. The first and second communication channels enable client-side inspection of communications.
