摘要： 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.

摘要： A method and system configured for personalizing at least one chip (IC), intended to be integrated into a smart card, comprising a tester (T) associated to a (Field Programmable Gate Array) FPGA device (WB) connected to the chip (IC), the chip (IC) being part of a wafer (W) comprising an arrangement of a plurality of chips and a disposable hardware module (HM) for verifying presence of the chip (IC) on the wafer (W). The tester (T) sends a first secret code (S1) to the FPGA device (WB), which sends a command (C) to the chip to initiate a test mode activation. The FPGA device (WB) encrypts a second secret code (S2) by using a secret encryption algorithm (E) parameterized with a true random number (R) received from the chip (IC) and the first secret code (S1) to obtain a first cryptogram M1 which is sent to the chip (IC). The chip (IC) determines a second cryptogram (M2) by carrying out a Boolean function (F) over a result obtained by decryption of the first cryptogram (M1) using the inverse of the secret encryption algorithm (E -1 ) parameterized with the random number (R) and the first secret code (S1). The second cryptogram (M2) is compared with a calculated result F(S2) obtained by carrying out the Boolean function (F) over the second secret code (S2) temporarily stored on the chip (IC). The FPGA device (WB) performs personalization of the chip (IC) only if the test mode of the chip (IC) is enabled by a successful comparison between the second cryptogram (M2) and the calculated result F(S2).

In one example system, a central conference call server establishes point-to-point connections with accessory devices comprising a secure element and connected to corresponding participant devices. The conference call server includes an interface to a plurality of secure elements configured to perform scrambling and unscrambling of media signals communicated to and from the accessory devices. In another example, one of the participant devices operates as the central conference call server. In other examples, participant devices communicate on a conference call via point-to-point connections between all accessory devices connected to the participant devices. The accessory devices include secure elements for decryption and encryption of media signals communicated between the accessory devices.
