METHOD AND SYSTEM FOR PROTECTING DATA, RELATED COMMUNICATION NETWORK AND COMPUTER PROGRAM PRODUCT

摘要

A method for securely storing at least one user's private information item, such as a private key (KID) for cipher processing, includes the steps of: - providing a communication network (TU, KR, IWF) wherein said user is allotted a respective subscriber identity module (SIM), and the subscriber identity module (SIM) stores at least one security algorithm (A8) ; - producing a cipher key (K) via said at least one security algorithm (A8); and - providing a remote storing location (KR) accessible by said user via the communication network wherein the user's private information items are stored as files encrypted via the cipher key (K).
