Flash Memory Using TPM Swissbit has come up with a
new solution: industrial flash memo- ry cards with embedded security that functions as a Trusted Platform Module (TPM). The solution is advantageous for IIoT component and solution developers and meets safety requirements along with per- forming other functions. The advantages kick in during
the integration phase, which becomes very simple for developers for a number of reasons. First, the memory interfaces are standardized, middleware for cryptographic opera- tions is available, and also, flash memories with TPM functionality are available in various form factors including SD cards, micro-SD cards and USB sticks. This solution is based on flash
memory modules, which for many years have been highly-rated for use in industrial conditions — such as a much larger temperature range than consumer/commodity cards as well as a far superior product life-span and availability. The company’s secure memory
cards, which are already widely used in large-scale deployments for wire- tapping-proof governmental mobile phones and police body cams, are mainly composed of a flash memory chip, a smart card and a controller. Their special firmware with integrat- ed Advanced Encryption Standard (AES) encryptor supports other application scenarios. The crypto chips that the company uses as secu- rity anchors provide secure commu- nication and encrypted data. This in

turn allows for Trusted Boot imple- mentation and license monetizing. Flash memory with an integrated encryptor can also be used to encrypt a system’s data storage devices such as classic hard drives.
Retrofitting Legacy Systems One of the obstacles to establish-

ing IIoT security is that older systems and components lack adequate protec- tion. Legacy systems and components that have USB or SD interfaces can be easily equipped with counterfeit- proof identities and can then be inte- grated into the existing security solu- tion. Retrofitting continues to be a key issue as the life cycles of security solu- tions and industrial memory cards are remarkably similar. Similar to memo- ry cards, security algorithms are sub- ject to wear and tear. As such, the length and algorithm requires contin- uous change to protect against increasingly sophisticated attacks. The ease of substitution makes the

through secure micro-SD card is pos- sible. After logging on, users are identified with a PIN which unlocks the secure authentication identifier, which cannot be copied. This is even possible through a PC by using a USB stick. This allows users with the defined required permissions to access the relevant systems securely at any time. Users who want secure process-
es such as encryption and two-factor identification in classic IT networks and on the Internet shouldn’t be sat- isfied with anything less in the IIoT. When it comes to machines,
robots or entire industrial installa- tions that run mostly autonomously based on sensor data to make deci- sions, it must be ensured that these only process or deliver data when the relevant data-transferring systems are uniquely identified. For this reason such systems
need to be equipped with counterfeit- proof identities. This can be provided by flash memory solutions that use crypto chips as TPM. Apart from being highly flexible, they can be retrofitted and can be combined with other functions such as encryption and data protection. There are many opportunities
for such applications, particularly in areas where industrial flash memory cards are already used. In medical equipment the security of patient data can be improved, and manipula- tion can be avoided during metering. In tracking logistics, industrial ter- minals can be safeguarded from external attacks, and secure process- es can be implemented with relative ease. Flash-memory combined with high security provides a truly smart solution.

combination of storage and security an ideal combination.
Security for Mobile Use Systems and installations used
in smart factories of the future will no longer have specific operating ele- ments and screens, but will instead be operated, monitored and main- tained by using mobile devices. The constant desire for mobilization and cost reduction ultimately shifts con- trol to mobile devices and thus into low-trust environments beyond a physically protected facility. But what are the security implications for mobile access? With the company’s solution,
