A provisioning control apparatus is arranged to be coupled to a provisioning equipment server electrically connectable with at least one electronic device for provisioning the electronic device with security sensitive provisioning data. The electronic device includes a processor, a volatile memory and a non-volatile memory. The provisioning control apparatus has a communication interface configured to securely provide a provisioning application code to the provisioning equipment server for storing the provisioning application code in the volatile memory of the electronic device. The provisioning control apparatus includes a processor configured to trigger the processor of the electronic device to execute the provisioning application code. The provisioning application code is arranged, when being executed by the processor of the electronic device, to store the security sensitive provisioning data in the non-volatile memory of the electronic device.

Provisioning control apparatus and method for provisioning electronic devices

A provisioning control apparatus is configured to be coupled to a provisioning equipment server, which is electrically connectable with one or more electronic devices for provisioning the one or more electronic devices with first or second program codes. The provisioning control apparatus comprises: a communication interface configured to receive an electronic credit token having a credit counter; and a processor. The communication interface is configured to transmit the first and second program codes towards the provisioning equipment server. The processor is configured to update a value of the credit counter for each transmission of the first and second program codes to obtain an updated credit counter, and to prohibit a further transmission of the first or second program codes if the updated credit counter indicates that a number of transmissions is reached. A provisioning control system comprises the apparatus and a corresponding method for provisioning one or more electronic devices.

Provisioning control apparatus, system and method

An electronic chip for assembly into electronic equipment includes a communication interface configured to receive a plurality of blocks of provisioning data from a provisioning apparatus in encrypted form. The electronic chip has a non-volatile memory configured to store the plurality of blocks of provisioning data. The electronic chip further includes a processing circuitry configured to perform a plurality of operations substantially in parallel, such that the plurality of operations includes a first operation of decrypting a first encrypted block of the plurality of blocks of provisioning data and a second operation of writing a second decrypted block of the plurality of blocks of provisioning data in the non-volatile memory.

Electronic chip and a method for provisioning such an electronic chip

A provisioning control apparatus coupled to a provisioning equipment server electrically connectable with electronic components each including a security enclave and a non-volatile memory. The provisioning control apparatus includes a processor configured to encrypt the security sensitive provisioning data using a secure vault encryption key for obtaining encrypted security sensitive provisioning data. The provisioning control apparatus has a communication interface configured to securely provide the secure vault encryption key to the provisioning equipment server for storing the secure vault encryption key in the security enclave of the electronic component. The communication interface is further configured to provide the encrypted security sensitive provisioning data to the provisioning equipment server for storing the encrypted security sensitive provisioning data in the non-volatile memory of the electronic component and thereby creating a secure vault in the non-volatile memory of the electronic component for securely storing the encrypted security sensitive provisioning data.

Provisioning control apparatus and method for provisioning electronic components for electronic devices

A provisioning system is provided for provisioning a plurality of electronic devices with provisioning data. Each of the plurality of electronic devices is associated with an electronic device type. The provisioning system includes a provisioning control apparatus, and a provisioning equipment configured to be electrically connected with at least one of the plurality of electronic devices for provisioning the at least one electronic device. The provisioning system includes a provisioning security module configured to receive the device type information from the provisioning control apparatus and to generate provisioning data on the basis of the device type information. The provisioning security module transmits the provisioning data to the provisioning equipment for provisioning the at least one electronic device with provisioning data. The provisioning security module maintains a provisioning counter indicative of a remaining number of the plurality of electronic devices that can be provisioned with provisioning data.

Provisioning system and method

A processor system includes a processor and a first memory area storing a boot program code. The boot program code starts execution of the operating system when executed by the processor, performs a cryptographic operation when processor executes the boot program code. A second memory area stores one or more cryptographic keys and is only accessible to the boot program code. A third memory stores the operating system. A communication interface receives data over a communication network. The processor retrieves the boot program code from the first memory area and executes the boot program code to start execution of the operating system. The processor terminates execution of the boot program code. The processor is configured to re-execute the boot program code while the operating system is executed to cryptographically encrypt data upon the basis of the cryptographic keys stored in the second memory area.

Processor system with a communication interface

A processor system includes a processor and a first memory area storing a boot program code. The boot program code starts execution of an operating system when executed by the processor, and performs a cryptographic operation when the processor executes the boot program code. A second memory area stores one or more cryptographic keys and is only accessible to the boot program code. A third memory area stores the operating system. The processor retrieves the boot program code from the first memory area and executes the boot program code to start the execution of the operating system. The processor re-executes the boot program code to cryptographically encrypt data upon the basis of the cryptographic keys stored in the second memory area.

Processor system

A provisioning control apparatus is configured for coupling to a provisioning equipment server electrically connectable with an electronic device(s) for provisioning the electronic device(s) with a program code. The apparatus comprises: a communication interface configured to receive an electronic provisioning token including a provisioning counter indicating a total of transmissions of the program code towards the provisioning equipment server; and a processor configured to retrieve the provisioning counter from the received token. The interface can transmit the program code towards server; the processor can update a value of the counter for each transmission of the program code towards the server for an updated counter. The processor prohibits transmission of the program code towards the server if the updated counter indicates a total number of transmissions has been reached. A provisioning control system includes the provisioning control apparatus and a corresponding method for provisioning includes one or more electronic devices.
