Abstract
A method of managing data in an electronic token includes an initial step of storing a first data into the electronic token and into a secured site. Secret data, intended to be initialized in the electronic token, is identified. Instructions and a subset of the first data are also identified, wherein the subset allows the secret data to be rebuilt by applying the instructions. A reference identifying the subset is sent to the electronic token. In the electronic token, the secret data is rebuilt from the first data and the reference by applying the instructions.
