Blurry Box Encryption Scheme and Why it Matters to Industrial IoT
These and other components need to be configured , calibrated , or replaced during initial commissioning or later maintenance , e . g ., calibrating an arm , the quality data of a spindle , or motor parameters . The process is time-consuming and requires highly trained staff .
It would be an immense benefit for all parties involved if components could be installed and replaced in a simple plug-and-play process , not unlike that known from USB devices . This creates a new challenge : plug-and-play processes must be secure to guarantee the safety of the machine and the quality of its output . It must also comply with all open standards and be interoperable to enable vendor independence . This can be achieved by using OPC UA for secure communication and standardized data with protected software that ensures integrity and protects the vendor ’ s know-how and USPs .
5.8 USE CASE : AUTOMOTIVE INDUSTRY
In modern cars , embedded software has become ubiquitous . One typical application for software protection would be the car diagnostic system . It needs to be updated regularly , as new models are brought to market and new part numbers or repair instructions are added . The diagnostic mechanisms contain a lot of AI ( artificial intelligence ) and know-how of the system ’ s vendor . Integrity is key , as are licensing and software protection .
Vendors of diagnostic systems use software protection to safeguard the know-how in their software and data and offer subscription-based licensing to car maintenance stations .
5.9 USE CASE : BANKING INDUSTRY
Automatic Teller Machines ( ATMs ) have to handle substantial amounts of cash and are exposed to severe threats : Gas is inserted to blow up the ATMs , banknotes are forged , and ATM software is manipulated with maintenance functions originally meant for authorized service staff only . The answer is software protection with strong authentication and mobile security devices like dongles . This offers strong protections for the integrated software , licensing for additional service functions , two-factor authentication with dongle and password , or time-limited authorizations that can be regularly renewed for authorized staff .
5.10 USE CASE : MEDICAL INDUSTRY
Software protection is used for protection against product piracy and integrity protection for embedded software to fulfill the regulatory standards for medical equipment ( such as FDA , Medical Products Act , etc .). Flexible feature licensing expands existing business models with payper-use schemes for dental , computed radiography , or medical diagnostics systems . Dental labs or dentists can buy machines at a reduced price and pay separately for the actual fillings produced by pay-per-use billing . Small laboratories , orthopedic doctors , and other healthcare facilities , who often cannot afford large upfront investments , can rent top-of-the-breed equipment , offer highly professional service , and stay competitive .
