Abstract
Systems, methods, apparatus and computer-executable instructions stored on computer-readable media for communicating a modified hash message authentication code (HMAC) signed message between two endpoints are provided. The HMAC signature of the message may include a plurality of components. In some cases, the HMAC signature is a Server Message Block (SMB) signature. The first and/or second endpoint may be a client, server, or host. Some embodiments of the present application utilize a proxy, such as a CIFS proxy. In one embodiment, HMAC signature information sent from the first endpoint to the second endpoint may be intercepted. A value for a component of the HMAC signature may be determined by, for example, using the intercepted HMAC signature information. The intercepted message may be modified, resigned using the intercepted HMAC signature information, and transmitted to a receiving endpoint.
