Title: Cryptographic key management for content protection
Inventor: ITKIS YEVGENY YAKOV GENE
IPC: H04L9/08
Filed: 2000-06-28
Abstract: A method for content access control enables authorized devices (110) to access protected content and prevents unauthorized devices (110) from accessing protected content. A plurality of authorized devices are divided into a plurality of groups (100), each of the authorized devices being included in at least one of the plurality of groups (100); no two of the authorized devices being included in exactly the same groups (100). It is determined whether at least one of the authorized devices is to be prevented from having access to the protected content and, if at least one device is to be prevented, all groups comprising the at least one device are removed from the plurality of groups, thus producing a set of remaining groups (40). Then an authorized set (60) comprising groups from the set of remaining groups (40) is found, such that each of the authorized devices (110) which was not determined to be prevented from having access is included in at least one group of the authorized set (60). To each of the authorized devices (110) is assigned a set of keys including one group key for each group of which the one device (110) is a member. At least some of the group keys are used for communication of a content decryption key to at least one of the authorized devices (110), and the utilizing step includes, for each of the authorized devices (110) obtaining the content decryption key, performing no more than a predetermined number of decryptions. This can be for broadcast or multicast, e.g. to personal stereo devices.

Title: Virtual machines on different servers interconnected via a virtual network with its own arbitrary addressing
Inventor: WRAY MICHAEL JOHN
IPC: H04L12/46
Filed: 2004-09-17
Abstract: Virtual machines (vm1, vm2) run on two different servers, each with its own virtual machine manager (alpha vmm, beta vmm). The invention allows the vmm's to establish virtual networks (vnet1, vnet2) to interconnect the vm's. The vmm's encapsulate the virtual network traffic for transport over the physical network and then decapsulate it at the destination. The system can be set up such that the network is maintained even when vm's migrate between hardware. The vm's may have arbitrary IP and MAC addressing on the virtual networks. Security encapsulation and virtual firewalls may also be implemented on the virtual networks. Virtual address resolution protocol (VARP) and virtual wide area networks are also possible.

Inventor: BAGAINI CLAUDIO
IPC: G01V1/37
Filed: 2007-03-09
Abstract: A method of performing a Vibroseis survey is described including the step of obtaining signals generated by activating vibratory sources at times To and T1, respectively, for a sweep period S and a listening time L such that T1 < To+S+L, wherein harmonic noise within the signals are attenuated using a first method to estimate the harmonics in a time-frequency interval in which harmonics of the sweep T1 overlap with the response to the fundamental of sweep T1 and using a second method for estimating the harmonics in a time-frequency with no overlap. In addition thereto, a method of attenuating the harmonic contamination of slip-sweep Vibroseis signals is described, using ground force signals or contamination-free signals and the Vibroseis signals to determine frequency dependent weights for at least a part of the frequency range of the Vibroseis sweep and using the frequency dependent weights to estimate the harmonics. The part of the frequency range referred to might be an overlap range in which the harmonics of a subsequent sweep overlap with a fundamental of an earlier sweep.
