Abstract
Method of controlling an electronic device and corresponding electronic device. The method may be performed by an electronic device (20) and includes steps such as receiving an instruction command (CMD) that includes identifiers (ID) of instructions (IS) that are prerecorded in a memory (30) of the electronic device; using the identifiers to form a code (RC) defining a set of instructions, where the set of instructions combines prerecorded instructions (IS) to execute a security check; and storing the code (RC) in a memory (28) of the electronic device in order to configure the electronic device (20) to execute the security check.
Claims14
A controlling method performed by an electronic device, said method comprising:
- storing, in a first ROM-type memory of the electronic device, a plurality of security check instructions configured to cause performance of one or more security checks of the electronic device, the plurality of security check instructions being in a deactivated state and enabling personalization of the electronic device;
- receiving an instruction command including identifiers identifying two or more security check instructions of the plurality of security check instructions;
- concatenating the received identifiers to create a code defining a set of instructions, wherein said set of instructions comprises the two or more security check instructions;
- and
- storing the code in a second memory of the electronic device accessed by a program executed by the electronic device, wherein the program performs a check of a transaction by executing the set of instructions defined by the code.
A non-transitory computer-readable data medium that includes instructions that, when executed by a processor of an electronic device, perform a method comprising:
- storing, in a first ROM-type memory of the electronic device, a plurality of security check instructions configured to cause performance of one or more security checks of the electronic device, the plurality of security check instructions being in a deactivated state and enabling personalization of the electronic device;
- receiving an instruction command including identifiers identifying two or more security check instructions of the plurality of security check instructions;
- concatenating the identifiers to create a code defining a set of instructions, wherein said set of instructions comprises the two or more security check instructions;
- storing the code in a second memory of the electronic device accessed by a program executed by the electronic device, wherein the program checks a transaction by executing the set of instructions defined by the code.
An electronic device comprising:
- a processor;
- a first ROM-type memory;
- a second memory;
- a non-transitory computer-readable medium storing instructions that when executed by the processor cause the processor to perform operations comprising:
- storing, in a first ROM-type memory of the electronic device, a plurality of security check instructions configured to cause performance of one or more security checks of the electronic device, the plurality of security check instructions being in a deactivated state and enabling personalization of the electronic device;
- receiving an instruction command including identifiers identifying two or more of the security check instructions;
- concatenating the received identifiers to create a code defining a set of instructions, wherein said set of instructions comprises the two or more security check instructions;
- and
- storing the code in a second memory of the electronic device accessed by a program executed by the electronic device, wherein the program checks a transaction by executing the set of instructions defined by the code.
