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.
