Abstract: A method and security system is provided for the secure and unequivocal encoding of a security module, for example, a chip card. A security module may be personalized during the manufacturing process in a secure environment, the manufacturer storing a unique identifier (IDSM1) in a memory of the security module. The secure encoding to ensure the uniqueness of the security module is achieved because the item of information to be kept secret and intended for the security module is encrypted not only by a communication key, but by the unique identifier (IDSM1) of the security module. This ensures that the item of information to be kept secret is able to be decrypted only by the security module with which the unique identifier (IDSM1) is associated, and used for safety-relevant applications.

Abstract: The present invention relates to a method and a security system for the secure and unequivocal encoding of a security module, in particular a chip card. To this end, a security module (10) is personalized during the manufacturing process in a secure environment in that the manufacturer stores a unique identifier (IDSM1) in a memory (14) of the security module (10). The secure encoding to ensure the uniqueness of the security module (10) is achieved in that the item of information to be kept secret and intended for the security module (10) is encrypted not only by a communication key, but by the unique identifier (IDSM1) of the security module (10). This ensures that the item of information to be kept secret is able to be decrypted only by the security module (10) with which the unique identifier (IDSM1) is associated, and used for safety-relevant applications.

Abstract: Generic information storage devices (magnetic, optical, biological/organic devices) are well-suited for storing, processing, archiving or transporting large amounts of information; they can, however, only be secured against unauthorized access using cryptographic methods. Undetected physical copying and manipulation of the information remains, however, possible. Disclosed is a process and device for combining non-intelligent generic information storage devices with intelligent storage devices and linking their information. The process compresses the stored data from a generic storage device and counts a signature count of the stored data. An ID is then provided to the stored data from a permanently assigned intelligent programmable memory chip. At least part of the compressed data is encrypted using an asymmetric key and transferred to a memory area of the permanently assigned intelligent programmable memory chip.
