Methods and systems for load balancing and failover among gateway devices are disclosed. One method provides for assigning communication transaction handling to a gateway. The method includes receiving a request for a license from a computing device at a control gateway within a group of gateway devices including a plurality of gateway devices configured to support communication of cryptographically split data. The method also includes assigning communications from the computing device to one of the plurality of gateway devices based on a load balancing algorithm, and routing the communication request to the assigned gateway device.

Intelligent NIC optimizations includes system and methods for Token Table Posting, use of a Master Completion Queue, Notification Request Area (NRA) associated with completion queues, preferably in the Network Interface Card (NIC) for providing notification of request completions, and what we call Lazy Memory Deregistration which allows non-critical memory deregistration processing to occur during non-busy times. These intelligent NIC optimizations which can be applied outside the scope of VIA (e.g. iWARP and the like), but also support VIA.

Methods and systems for monitoring network data packets within a secure network are described. One method includes receiving, at a consumer endpoint, a data packet from a second endpoint, the data packet being encrypted with an encryption key associated with a packet auditing community of interest and having a routing header appended thereto, the routing header identifying the consumer endpoint. The method includes decrypting the data packet using the encryption key associated with the packet auditing community of interest, and removing at least a portion of the routing header identifying the consumer endpoint from the decrypted data packet. The method also includes performing at least one packet auditing operation on the decrypted data packet.

A method of communicatively connecting first and second endpoints across a NAT and/or PAT router to form an IPSec encrypted tunnel is disclosed. A message is received by the first endpoint from the second endpoint. The message includes an encrypted portion including a source port, a destination port, a source IP address, and a destination IP address. It is determined whether a table entry exists for the message. If Yes, it is determined by the first endpoint whether a NAT router and/or a PAT router is between the first endpoint and the second endpoint based, at least in part, on the table entry and the encrypted portion of the message. If Yes, an IPSec encrypted tunnel is created using IPSec transport mode for further communications between the first and second endpoints. An apparatus and a computer program product are also disclosed.

Methods of communicatively connecting first and second endpoints are disclosed. One method includes transmitting from a first endpoint to a second endpoint a connection request, the connection request including an IP address of the second endpoint. The method further includes, based at least in part on the IP address of the second endpoint, selecting IPsec from among a plurality of available security protocols to first attempt to use in forming a tunnel between the first and second endpoints, and forming the tunnel between the first and second endpoints based on the connection request.

A method and system for establishing secure communications between endpoints includes transmitting a first message including a token having one or more entries each corresponding to a community of interest associated with a user of the first endpoint and including an encryption key and a validation key associated with the first endpoint. The method includes receiving a second message including a second authorization token including one or more entries, each entry corresponding to a community of interest associated with a second user and including an encryption key and a validation key associated with the second endpoint. The method includes, for each community of interest associated with both users, decrypting an associated entry in the second authorization token to obtain the encryption key and validation key associated with the second endpoint. The method also includes generating a shared secret based on the key pair, transmitting a third message including the created key pair to the second endpoint, and initializing tunnel using the shared secret to derive encryption keys used for IPsec-secured communications between the endpoints.

A secure communications arrangement including an endpoint is disclosed. The endpoint includes a computing system. The computing system includes a user level services component and a kernel level callout driver interfaced to the user level services component and configured to establish an IPsec tunnel with a remote endpoint. The computing system also includes a filter engine storing one or more filters defining endpoints authorized to communicate with the endpoint via the IPsec tunnel. The computing system also includes a second kernel level driver configured to establish a secure tunnel using a second security protocol different from IPsec.
