Abstract: A peripheral devices switch, a peripheral device, and a keyboard configured to be connected to a plurality of host computers. The peripheral devices switch configured to be coupled to at least one set of peripheral devices and to a plurality of host computers. A color is assigned to each host computer and the at least one set of peripheral devices illuminates at least one polychromatic light source with the color that is assigned to an active host computer. A peripheral device interface to interface between the peripheral device and the peripheral devices switch may be a composite interface comprises two independent interface protocols either by sharing a single connector and cable but having separate pins in the connector and corresponding wires in the cable, or by having a separate cable and separate connector to each one of said interface protocol.

Abstract: Mediating between host and display where a mediator enforces security policy over bidirectional protocols of a Display Data Channel (DDC) of video communication protocols between host and display, where AD-EDID display emulators are coupled to DDCs of the host's video port, AD-EDID host emulators are coupled to DDCs of display's video port and security enforcing communication units couple between pairs of AD-EDID display emulator and AD-EDID host emulator, where AD-EDID display emulators emulate display operation and behavior over the DDC, AD-EDID host emulators emulate host operation and behavior over the DDC and security enforcing communication units enforce security policy such as unidirectional communication between the pairs of AD-EDID host emulators and AD-EDID display emulators.

Abstract: Systems and methods of a peripheral devices switching system configured to be connected to a plurality of host computers, including at least one set of peripheral devices, a peripheral devices switch that is to be coupled to said at least one set of peripheral devices and said plurality of host computers, where the peripheral devices switch assigns a color to each host computer, and couple between said at least one set of peripheral devices and an active host computer, and one or more polychromatic light sources that are being comprised in the peripheral devices switch, the at least one of the peripheral devices of the sets of peripheral devices or both, where the peripheral devices switch indicates the active host computer by illuminating at least one polychromatic light source by the color that is assigned to the active host computer.

Abstract: A USB security gateway device is integrated within a host computer. The USB security gateway device is used for protecting a USB port of a host computer against interaction with unauthorized USB device. The USB security gateway device qualifies any USB peripheral device before it allows it to interact with the host device. Qualification parameters are stored in the USB security gateway device and are reprogrammable.

Abstract: A security implant device and a method of operation of the security implant, for securing Voice over IP (VoIP) phone, the implant device disables audio input and output components of the VoIP phone in order to prevent audio eavesdropping.

Abstract: A secure cellular communication system comprises a modified smartphone mated with a security pack. A Cryptographic module within the security pack encrypts all cellular outgoing data and decrypts cellular incoming data. The modified smartphone is modified to rout all cellular outgoing data and incoming data via the Cryptographic module within the security pack. The cellular MODEM may reside within the security pack while the phone's cellular MODEM is disabled, or the phone's cellular MODEM may be used.

Abstract: A portable computer providing high level of security comprises of two completely logically and electrically isolated computer modules within one tamper resistant enclosure. One computer module is for Higher-Security applications (refer higher-security to as “red”) and the other is for Lower-Security applications such as email and internet (refer lower-security to as “black”). The two modules are coupled together to secure Peripheral Sharing Switch that enables intuitive user interaction while minimizing the security risk resulted from sharing same peripheral device.
