摘要： Devices and methods for masking and unmasking sensitive data, based on a standard cryptographic algorithm defining a ciphering algorithm, and a deciphering algorithm using more resources than the ciphering algorithm are described. The masking of sensitive data is done by applying the deciphering algorithm to the sensitive data to obtain masked sensitive data. The unmasking of the masked sensitive data is done by applying the ciphering algorithm to the masked sensitive data to obtain sensitive data in plain form.

摘要： A smartcard (1) includes: a first and a second microprocessor (110, 210), elements for receiving (14) commands each coming from a first or a second communications channel external to the card (1) and for transmitting the received commands to the first microprocessor, characterized in that the first microprocessor includes elements for determining (706) whether a received command has been received on the second communications channel so as to transmit (708) the received command to the second microprocessor (210) in the case of a positive determination. Notably, the determination can be carried out by detecting an electrical contact of the communications interface of the card, over which the command is received. Application of the invention to a card having a second microprocessor for executing a highly securitized application, of the banking transaction type, and a first less securitized application, of the mobile telephony application type.

摘要： The method includes in placing an instruction presence parameter in the “argument” field of a binary word defining a read/write command generated by generic management programs (drivers) for removable data storage units. This makes it possible to circumvent the limitation of the set of the commands authorized by a generic program for managing a removable data storage unit, without running the risk of data being interpreted wrongly as instructions.
摘要翻译：该方法包括将指令存在参数置于定义由用于可移动数据存储单元的通用管理程序（驱动器）生成的读/写命令的二进制字的“参数”字段中。这使得可以避免由用于管理可移动数据存储单元的通用程序授权的命令集的限制，而不会将数据错误地解释为指令的风险。

摘要： Process for reclaiming storage spaces in a microcircuit card when they are no longer used by the references of the system. Each storage space (EM1-EM4) is provided with a header (E1-E4) containing a number of references representative at any moment of a plurality of references requesting the data of the corresponding storage space. The headers form the object of chaining (Ch) and a storage space the number of references of which has been reduced to zero can be re-allocated. Under certain conditions, available and adjacent storage spaces can be merged.

摘要： The method of protection of a microcircuit against an attack includes: a step (205) of determining if an attack has been detected, if an attack has been detected, a step (210, 510) of executing a protection function, and if no attack has been detected, a step (215, 515) of executing a decoy function simulating the protection function and perceptible from outside the microcircuit in a manner substantially identical to the protection function. In some embodiments the decoy function has a power consumption substantially identical to that of the protection function, the protection function effects a step of writing predetermined data at a first address of a non-volatile memory, and the decoy function effects a step of writing in non-volatile memory at a second address different from the first address.
