Abstract
A method of read or write access by an electronic component of data, including generating a first secret key for a first data of an ordered list of data to access, and for each data of the list, following the first data, generating a distinct secret key by means of a deterministic function applied to a secret key generated for a previous data of the list, and the application of a cryptographic operation to each data to be read or to be written of the list, carried out by using the secret key generated for the data.
