Title: Countermeasures against cache attack by reducing cache leakage between secure and non secure processes using the same cache.
Inventor: HARRIS PETER WILLIAM
IPC: G06F12/0891
Filed: 2007-05-02
Abstract: A method of impeding leakage of cache access information of a section of a sensitive process 40 to an untrusted process 30, said sensitive and untrusted processes being performed by a processor 12 within a data processing apparatus. The processing apparatus comprises at least one cache 60 operable to store information required by said processor while performing said sensitive and untrusted processes. Prior to commencing processing of a section of the sensitive process by said processor, information stored in locations in the cache that may be used or required by the sensitive process are evicted before the sensitive process is executed. When the processor switches between the sensitive process and the untrusted process in response to a switching requestor on switching back to the sensitive process from said untrusted process, information stored in locations of said at least one cache which may be required by said section of said sensitive process is also evicted prior to recommencing the processing of the sensitive process. The method provides a countermeasure against side channel cache attacks or cache timing attacks. The method has a specific use in cryptographical systems.

Title: A noise-shaped pulse shuffler for a double-sided pulse-width modulator
Inventor: MAGRATH ANTHONY JAMES
IPC: H03M7/32
Filed: 2005-01-17
Abstract: If the digital input to a double-sided PWM modulator in a class-D audio amplifier is an odd number the resulting PWM pulse cannot be centred exactly in a frame comprising an even number of clock periods. To accommodate odd pulse lengths the offset generator 37 determines the start time for the output pulse with reference to the beginning of the frame, and when this is not an integer the quantiser 38 rounds the offset to a whole number for input to the modulator 34. The output pulse may thus be shuffled by half a clock period to the right or left, but the noise-shaping feedback loop ensures that the average quantization error is zero and spectrally shapes the error to reduce quantization noise in the audio band.

Title: Identifying recipient nodes in P2P communications
Inventor: HIIE MAGNUS
IPC: H04L45/16
Filed: 2009-04-14
Abstract: In a packet-based peer-to-peer (P2P) network, a source node 104 generates a first identifier ("stream ID") for the content of a data stream (of eg. VoIP, video or text data) and also a second, distinct identifier ("tag") which identifies the destination group of end-user nodes 126-146 which will receive the stream after routing via an intermediate ("relay") node 402. Each intermediate node only receives the second identifier and so does not know the content of the data stream, which maintains the end-user's privacy by preventing intermediate nodes from participating in their group or republishing the content, and allows data stream target audiences 412-422 to be managed independently of the content. Encryption at the source node, with the encryption keys being transmitted to end-user nodes, further hampers an intermediate node's attempt to read the content or the first identifier, while the second identifier is generated from a hash of the first identifier known only to end-users and remains unencrypted. The first identifier may also be transmitted via a different channel (eg. a secure call-establishment, multicast or instant messaging channel) to the subsequent data stream, and third identifier may be used to identify audiences 414 & 422 comprising further recipient nodes for the stream to be routed to.

Torque generated by the turbomachinery lubricant pump 18 is transferred through an accessory gearbox 12 to a spool 4, 6, 8 of the core engine 2 and to a fuel pump 16. Control of the pitch of blades 36 of the propeller 22 enables the windmilling propeller 22 to achieve a desired speed of the spool 4, 6, 8 and output of the fuel pump 16 sufficient to restart the engine 2, even at low air speeds.
