SAFE DATA STORAGE WITH INTEGRITY PROTECTION Russian patent published in 2010 - IPC G06F12/14 

FIELD: information technology.

SUBSTANCE: inner but not integrated safety token is proposed for device, which includes a first integrated circuit which includes a central processor. The safety token is provided by a second integrated circuit which is separate from the first circuit. The second integrated circuit includes secure nonvolatile memory. A secure processor sends information to the second circuit in protected form for safe storage of protected information in the secure nonvolatile memory, and the second integrated circuit sends information stored in the secure nonvolatile memory to the secure processor in protected form. Information transfer is protected by cryption apparatus. The first integrated circuit and the second integrated circuit are inner parts of the device. Disclosed also is an initialisation method for distributing a protected key shared by circuits and for cryptographic purposes.

EFFECT: better information protection.
