Abstract

The present invention provides for a security device for location within a network device and having first and second Medium Independent Interfaces for functional connection within the network device, whereby the MII interfaces can callow for location of the security device between a PHY chip and a MAC chip of the host network device.

Claims

1. A security device arranged for location within a network device and having first and second Medium Independent Interfaces for functional connection within the network device.

2. A security device as claimed in claim 1 and arranged for incorporation into an Ethernet terminal device.

3. A security device as claimed in claim 1 and located between a PHY device and MAC device of a host network device.

5. A security device as claimed in claim 1 and arranged to include first and second Media Independent Interfaces for connection to a MII bus.

9. A security device as claimed in claim 1 and comprising an ASIC or FPGA with integrated CPU.

10. A security device as claimed in claim 1 and arranged to employ a network node identifier from a host, or other, network device.

11. A security device as claimed in claim 1 and arranged with coding to allow access by a remote Configuration Management Platform.

12. A network device including a security device as claimed in claim 1.

13. A network arrangement including at least one network device as claimed in claim 12.

4. A security device arranged for location within a network device and to be interfaced between a MAC device and PHY device of a host network device.

6. A security device including first and second interfaces arranged for interfacing within an Ethernet terminal device.

7. A security device as claimed in claim 6 and arranged to interface between a PHY device and MAC devices within the terminal device.

8. A security device as claimed in claim 6 and including first and second Media Independent Interfaces.
