Abstract: The “first” portable electronic entity (100) includes elements (105) for connection to a host station and a memory (120) storing instructions of an application (121) adapted to be at least partially loaded into the host station, to be executed by the host station and to collaborate with a server connected to the host station to effect the personalization of a “second” portable electronic entity (100). In embodiments, the second electronic entity is the first electronic entity. In embodiments, the application is at least partially executed by the first portable electronic entity.

Abstract: A method of protecting a secure USB key comprising: a step of obtaining at least one parameter concerning the use of a function that can be executed on said key; a step of detecting at least one blocking condition that depends on said parameter, and where appropriate, a first check step suitable for preventing the execution of said function; a step of detecting at least one determined event independent of said function; and a second check step suitable for authorizing the execution of said first check step only in the event of said determined event being detected, said second check step being active even when said blocking condition is not satisfied.

Abstract: The invention concerns a microcircuit card comprising means (RX) for receiving a command and means for modifying at least one performance of the card capable of being implemented after a step of personalization of the card.
