Abstract
The present invention relates to a method to protect, in a secured container using an encryption key, a set of mixed sensitive and public data to be transferred to an entity. The method includes the steps of: generating a random key, ciphering the set of mixed sensitive and public data using said random key to obtain a ciphered set of data, generating an initialization value, and defining configuration information for the secured container. The initialization value, the configuration information and random key form a preamble. The preamble and the ciphered set of data are encrypted. The initialization value renders the resulting encrypted data variable from a secured container to another even in case of repetitive configuration information in the preamble.
