20120195429METHOD AND SYSTEM FOR SECURELY SCANNING NETWORK TRAFFIC - Secure network communications via a firewall device are provided between a first device and a second device, where an encryption parameter is shared by the devices. A data packet sent by the first device may then be copied within the firewall device, so that the copy of the data packet can be decrypted within a portion of the firewall device. In particular, the portion of the firewall device in which decryption takes place is defined such that contents of the portion are inaccessible to an operator of the firewall device. Thus, scanning of the decrypted copy of the data packet for compliance with a predetermined criterion may take place within the firewall device, without an operator of the firewall device having access to the contents of the data packet to be transmitted. Thereafter, the original data packet can be forwarded to its originally intended recipient.2012-08-02
20120195430Quantum Key Distribution - An apparatus including: an input optical interface configured to receive a series of optical input signals each including photons; an encoder configured to encode a quantum key for distribution by encoding each of the series of received optical input signals with a measurable state; an attenuator configured to attenuate each of the encoded optical input signals to create a series of quantum optical signals; and an output optical interface configured to send the series of quantum optical signals to the remote apparatus via a quantum communication channel.2012-08-02
20120195431METHOD FOR OPERATING A NODE IN A WIRELESS SENSOR NETWORK - The present invention relates to a method for operating a first node in a network, the network including a plurality of nodes, the method comprising (a) the first node having a first identifier joining the network by transmitting the first identifier to a second node having a second identifier, (b) the first node generating a first key on the basis of the second identifier (c) the first node authenticating the second node by means of the first key, (d) the first node communicating with a third node if the first and second keys are equal.2012-08-02
