Method for the operation controlled by encryption of data resources stored in a database associated with a computer system.System for holding controlled by encryption of data resources, communication network, and computer program product.An arrangement for operation controlled by encryption of data resources (for example, to store and recover certainly sensitive data or record certainly and subscribe to a system of computadOr) includes the steps of: providing a subscriber identity module (SIM) and a security algorithm; generating at least one, for example two, random values (rand1,Rand2); subjecting the random values (rand1, rand2) to at least a security algorithm to generate at least one, for example two keys of session (KCl,Kc2); processing the session key (KCl,Kc2) by a function of the mixer (H) as a hash function to generate an encryption key; and using the encryption key (k) thus produced to explore the features of the data.
