DEC has announced a product that provides network security. The box is called the "Digital Ethernet Secure Network Controller" or DESNC and has a companion software product known as "VAX Key Distribution Center" or VAX KDC. The DESNC is attaches to the ethernet via a transceiver and has four thinwire ethernet ports. Client nodes attach to the TW ports. To quote DEC: "Together the DESNC controller and VAX KDC system implement a default access control policy that enables all nodes on a network to communicate with each other (after successful authentication). This allows for rapid integration of DESNC controllers and VAX KDC systems with minimal impact on existing network operatons. Under this open policy, client nodes (i.e., nodes connected to DESNC controllers) communicate with each other using encrypted frames on the network. All other communication (i.e., client node-to-node, and node-to-node) is unencrypted (see example configuration below)." //=+=========+======+== ethernet =+=========+===================// | | | | | | | | | | --------- --------- | --------- --------- | | | | | | | | | | DESNC | | Node | | | Node | | DESNC | | | | | | | | | | --------- --------- | --------- --------- | | | | | | --------- --------- --------- | Client| | KDC | | Client| | Node | | DESNC | | Node | | | | | | | --------- --------- --------- | | --------- |VAX KDC| | Node | | | --------- I have only see a sales document that announces the product but not any detailed information. So, call your friendly DEC salesperson. Butch

hi i have more questions about DECs product announcement: DESNC. i think the 'black box' must have the following hardware-design _________________________________________________ | | | ----------------- | | | | | | | shared memory | | | | | | | ----------------- | | x | | xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx | | x x x | | --------- --------- --------- | | | 82586 | | 80186 | | 82586 | | | --------- --------- --------- | | X X | --------X-----------------------X---------------- X X connected to LAN connected to station it may be that the DESNC also have a speciall encryption-chip. who has information about the hardware design of the DESNC? how do the KDC communicate with the DESNC (e.g. data link service or transport service or ?)? which parts of the iso-protocol are encrypted? what is the price? norbert Norbert Fuchs Ultrasoft Co.
