Abstract: A method for securing transmission of digital data in a communication network comprising a central station or a terminal and at least one device monitored by the central station via the communication network. The at least one device is configured to produce and to transmit a digital data stream to the central station or terminal. The at least one device further comprises a secure non-volatile memory for storing at least device specific information. The at least one device forms a data block based on at least the device specific information stored in the secure memory. The data block thus formed may compose additional data to be merged with the digital data stream produced by the at least one device.

Abstract: Public-key cryptography allows putting into practice concepts of digital signatures and public-key key exchange; methods used on a daily basis in digital systems. A method generates a protected secret value k? used as a first operand in a cryptographic group operation involving a base group element G of order n and including: generating random positive integers k1 and k2, that are strictly smaller than the order of the group element G due to a cryptographically secure random number generator, such that the generated random positive integers k1 and k2 do not share any divisor with the order n other than 1; generating the protected secret value k? based on the generating random positive integers such as k?=k1*k2, the protected secret value k? being used as a second operand in the group operation.

The malware detection logic may establish a secure communication channel between the malware detection logic of the secured device and the security client of the destination device. The malware detection logic may execute a validation test on the message to determine that the message includes malware. The malware detection logic may report an alarm to the security client of the destination device. The malware detection logic may transmit information related to the malware to a cloud computing server. The malware detection logic may prevent an application associated with the destination device from processing the message.

Abstract: Disclosed herein are methods and systems for link-based enforcement of routing of communication sessions via authorized media relays. In an embodiment, a media relay receives encrypted first payloads from a first endpoint and encrypted second payloads from a second endpoint as part of a session. The encrypted first payloads require a first key for decryption and the encrypted second payloads requite a second key for decryption. The media relay is preconfigured prior to the session with secrets useable for identifying the first and second keys. The media relay decrypts the first payloads using the first key and decrypts the second payloads using the second key, and transmits the first payloads to the second endpoint and the second payloads to the first endpoint as part of the session.

Abstract: A method to protect a device key in a device comprising at least one secure element locally connected to at least one time programmable memory storing a global value in form of a bit string comprising locked bits and unlocked bits. The locked bits are irreversibly pre-programmed in the one-time-programmable memory during an initialization phase of the device while the unlocked bits remaining in an initial state may be programmable by the secure element. The secure element is configured to generate, at initialization of the device, a device specific value by using the global value, program the device specific value previously obtained in the one time programmable memory, and erase the global value by programming the unlocked bits of the corresponding bit string. A further object of the disclosure includes a device configured to carry out the method.

Abstract: A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.
