licenses, and the identification of participants in machine-to- machine (M2M) communica- tions. At the same time, system developers retain flexibility in hardware selection, as only standard SD memory or USB interfaces are required. The TPM functionality can be imple- mented or customized individu- ally from the SmartCard in the secure storage card as a JavaCard applet.

long-term available flash memory media for industrial use and offers secure memory cards. These cards consist of a flash memory chip, a
flash controller and a SmartCard — in this case, a JavaCard SmartCard with common critera level EAL 5+ certificate. The special firmware with inte-
grated AES encryptor enables other applications. Because a crypto ele- ment is used as secure element, both data and communications can be encrypted. This allows for trusted boot designs to be implemented and for licenses to be secured. Here, TPM and memory are not

separated, as is the case for a stan- dard TPM, which facilitates brute force attacks. The memory and the security chip are connected as one inseparable unit and combine plat- form security and data protection. The flash memory with encryptor can also be used to encrypt addition- al data memory within the system, for example conventional hard drives. These kinds of flash memory cards are already in use on a large scale in tap-proof mobile phones, police body cams and for the protec- tion of patient data in medical tech- nology.
The integrated SmartCard pro-

vides an ID as proof of identity, which in turn can be used for forgery and integrity protection. Counterfeit devices pose not only an economic problem for manufacturers, but also a risk for users, such as in medical technology. Uniquely identifiable data memory ensures the hardware and software combination complies with the manufacturer’s specifica- tions.
A secure flash memory card
allows for software license manage- ment and feature activation. By inte- grating access control, code encryp- tion or digital signatures, different software configurations for products can be defined and managed. This is becoming more important for mechanical and plant engineering, due to maxed out and fine-tuned mechanics. Today, many machines only differ in their “smart” software functions.

the internet face particularly danger- ous risks. Remotely serviced systems, such as industrial controls, are vul- nerable by default. Data encryption and unique identifiability of M2M communication participants provides the ideal solution. Similar to the pro- tection of online communications in IT, where users identify themselves as part of a two-factor authentication using a SmartCard token, memory modules with secure element provide the option to give M2M communica-
