Methods and systems are provided for authenticating a device on a network. A method (204) includes receiving a message from the device (130), the message cryptographically signed with a device private key. The message (600) includes a device identifier (500) that is computed (402), using the device private key, from at least one descriptor of a hardware component associated with the device, a counter value (604) associated with the device identifier; and a service key request (608). The method further includes verifying (416) the message signature using a device public key. The received counter value is verified (412) to be greater than a previously received counter value associated with the device identifier. A service key is generated (418) and linked to the device identifier. The service key is sent (424) to the device to enable it to communicate through secure network connections.
Systems and methods for maintaining cryptographic revocation lists are provided. A method includes determining that a cryptographic certificate (152) should be revoked. Based on the determination, a certificate revocation message is broadcast to a network of client devices (140). The certificate revocation message includes an identifier associated with the cryptographic certificate. Each client device that receives the certificate revocation message updates a list (144) maintained by the client device. The updated list indicates that the cryptographic certificate (152) identified by the identifier is no longer valid.

Communication apparatus capable of implementing a selected communication protocol
A communication apparatus is disclosed with a communication controller that has a host-side communication interface for communicating with a host and a plurality of slave-side communication interfaces. Each slave-side communication interface has a plurality of electrical pins that are configurable to define a communication port that implements a selected communication protocol thereon. Each pin is in electrical communication with a slave socket having a predetermined layout. Each slave socket is configured to receive a protocol adapter that corresponds to the selected communication protocol and that is configured to facilitate communication between an external slave device and the relevant communication port.

The invention relates to a software defined device interface system 10, a software defined device interface, gateway and a method of defining an interface for a device which uses a specific communication protocol for communication purposes. The system 10 includes a microprocessor/processing unit 12.1, 12.2 with a plurality of communication pins and software/firmware. The software/firmware is configured, based on a specific communication protocol which is used by a particular device 30.1-30.4 for communication purposes, to, in runtime, assign/select one or more of the communication pins to form a virtual port to which the particular device 30.1-30.4 can be connected, upon receiving a configuration instruction from a user to implement the specific communication protocol. The software/firmware is further configured to implement the specific communication protocol through the virtual port, to thereby allow for communication between the microprocessor/processing unit 12.1, 12.2 and the device 30.1-30.4, when the device 30.1-30.4 is connected to the pin(s) of the virtual port.
