| 20090116650 | METHOD AND SYSTEM FOR TRANSFERRING INFORMATION TO A DEVICE - Methods and systems for transferring information to a device include assigning a unique identifier to a device and generating a unique key for the device. The device is located at a first site, and the unique identifier is sent from the device to a second site. The unique key is obtained at the second site, and it is used for encrypting information at the second site. The encrypted information is sent from the second site to the device, where it can then be decrypted. | 05-07-2009 |
| 20090172392 | METHOD AND SYSTEM FOR TRANSFERRING INFORMATION TO A DEVICE - A system and method for transferring information include generating a public/private key pair for programming equipment and sending the programming equipment public key to a certificate authority. A programming equipment certificate is generated using the programming equipment public key and a private key of the certificate authority. The programming equipment certificate and a certificate authority certificate are sent to the programming equipment. Information is transferred to or from the programming equipment in response to an authentication using the programming equipment certificate and the certificate authority certificate. | 07-02-2009 |
| 20090172401 | METHOD AND SYSTEM FOR CONTROLLING A DEVICE - A system and method for controlling a device. Data that was encrypted using a first encryption scheme is decrypted, then re-encrypted using a second encryption scheme. The re-encrypted data is then decrypted. | 07-02-2009 |
| 20090204656 | PSEUDO RANDOM NUMBER GENERATOR AND METHOD FOR GENERATING A PSEUDO RANDOM NUMBER BIT SEQUENCE - A pseudo random number generator including a plurality of non-singular feedback shift registers each configured to output a bit-sequence. At least a first of the plurality of non-singular feedback shift registers has one or more first cycles of a length less than or equal to two, and a second of the plurality of non-singular feedback shift registers has one or more second cycles of a length less than or equal to two, and the one or more first cycles encompass a first set of one or more of shift-register state vectors 000 . . . , 111 . . . , 010 . . . and 101 . . . and the one or more second cycles encompass a second set of one or more of the shift-register state vectors 000 . . . , 111 . . . , 010 . . . and 101 . . . with the first and the second set being disjoint. | 08-13-2009 |
| 20090204657 | HYBRID RANDOM NUMBER GENERATOR - A hybrid random number generator (HRNG) including an output, a combinational logic, a TRNG, and a PRNG. The HRNG is configurable to operate in a first and a second mode, wherein in the first mode the PRNG is serially connected between the TRNG and the output and the TRNG intermittently influences the PRNG, and in the second mode the TRNG and the PRNG are connected to the output via the combinational logic. | 08-13-2009 |
| 20100031026 | METHOD AND SYSTEM FOR TRANSFERRING INFORMATION TO A DEVICE - A system and method for transferring information to a device include sending a first challenge from an information provider to programming equipment, and responding to the first challenge by the programming equipment. A second challenge is sent from the programming equipment to the information provider, which responds to the second challenge. Information is encrypted by the information provider and sent from the information provider to the programming equipment. | 02-04-2010 |
| 20100182147 | REMOTE STORAGE OF DATA IN PHASE-CHANGE MEMORY - A security circuit comprising including a sensor located remotely from a central alarm handler and configured to sense an attack, and a phase-change memory cell coupled to and located remotely with the sensor, and configured to store an alarm event when the attack is sensed. | 07-22-2010 |
| 20100301896 | PHASE-CHANGE MEMORY SECURITY DEVICE - A semiconductor chip having a subcircuit formed in a substrate; and a phase-change memory cell located on the subcircuit, and configured to directly detect an attack on the subcircuit, or to form a shield to prevent physical access to the subcircuit. | 12-02-2010 |
| 20100316217 | GENERATING A SESSION KEY FOR AUTHENTICATION AND SECURE DATA TRANSFER - A device for generating a session key which is known to a first communication partner and a second communication partner, for the first communication partner, from secret information which may be determined by the first and second communication partners, includes a first module operable to calculate the session key using a concatenation of at least a part of a random number and a part of the secret information. The device also includes a second module operable to use the session key for communication with the second communication partner. | 12-16-2010 |
| 20110069528 | ELECTRONIC DEVICE WITH A PROGRAMMABLE RESISTIVE ELEMENT AND A METHOD FOR BLOCKING A DEVICE - One or more embodiments relate to an electronic device comprising a circuitry and a programmable resistive element. The programmable resistive element comprises a first and a second state, wherein the programmable resistive element is configured to allow switching from the second state into the first state in response to a signal comprising at least a predefined level. The circuitry is configured to provide signals up the predefined level, wherein the circuitry is configured to provide a switch signal to the programmable resistive element, wherein the switch signal causes switching from the first into the second state. | 03-24-2011 |
