摘要： A mediator and a method for securing a mediator for coupling between one or more hosts and one or more consoles comprising one or more peripheral devices. The mediator is having at least three stages: (i) a security setup stage; (ii) a neutralization stage; and (iii) a normal operation stage. In the normal operation stage, the mediator couples between at least one of the one or more peripheral devices and at least one of the one or more peripheral devices. In the neutralization stage the mediator disable coupling between at least one of the one or more peripheral devices and at least one of the one or more peripheral devices. The securing method starts with the security setup stage after at least one of (a) a power-up; (b) a reset; (c) a device connection; and (d) an unlock command. Upon entering the security setup stage, the method performs the following: (1) reading the device information of the one or more peripheral devices; (2) if the mediator is in Unlock state, waiting for a locking command and upon locking command arrival, register the information of the one or more peripheral devices to non-volatile memory, and proceed to normal operation stage, (3) if the mediator is in Lock state, compare the registered information of the one or more peripheral devices with the information read previously, and upon a match proceed to normal operation stage and upon a miss-match proceed to neutralization stage. The lock and unlock commands are provided from an authorized user or an administrator.

摘要： A transceiver for sending and receiving data from a controller area network (CAN) bus is disclosed. The transceiver includes a microcontroller port, a transmitter and a receiver, wherein the transceiver is configured to determine bit timings from a data frame received by the receiver. The transceiver is further configured to detect attempts to introduce a signal glitch in a predetermined portion of the data frame and upon detection of the signal glitch, the transceiver is configured to invalidate the data frame on a transmission line and/or disable the transmitter for a predetermined period.

摘要： Communication buses enable devices to communicate and exchange information and control signals. There is a growing concern over the security of such types of buses. Since any device can transmit any message, and device on the bus which can be compromised poses a threat for the bus. Described is a system to authenticate the source of messages from various devices on a communication bus.

摘要： Methods, computer program products, and systems are presented. The Methods, computer program products, and systems can include, for example: examining hardware device transmitted data received through an I/O interface port of a computer system; determining in dependence on the examining whether the hardware device transmitted data received through the I/O interface port of the computer system satisfies a criterion; and in response to determining that the hardware device transmitted data received through the I/O interface port of the computer system satisfies the criterion, initiating a security process for protecting the computer system.
