Secure Activation Licensing Technology is the Algodone patented technology developed to secure connected objects networks.
SALT™ OFFERS A WIDE RANGE OF FUNCTIONS
All functions needed to manage the life cycle of distant connected objects are available in SALT™.
Because all critical processes are achieved in hardware, resistance to attacks is significantly improved with SALT™.
SALT™ is made of fully validated IPs available off the shelf.
THE SALT™ TECHNOLOGY
SALT™ offers a wider range of functions to manage the life cycle of connected objects
Prior to communicating with the objects, those must be clearly identified and registered. SALT™ sets a secure communication channel that will guaranty the security of all the transactions between the server and the objects.
Objects or functions inside the objects can be dynamically personalized. An object or a function can be programmed to operate in different modes. Netlist obfuscation techniques are used to secure against reverse engineering.
Events or time can be counted and results returned to the license server.
Thanks to control registers, coded informations can be returned to the license server.
WHY IS SALT™ UNIQUE ?
Algodone extends the secure communication channel down to the internal functions of the objects.
END TO END
SALT™ establishes a secure communication channel between license server and the functions to be controlled inside the objects.
SECURED BY HARDWARE
All the treatment of the information inside the objects is done in hardware (no software intervention), at any time, no information in clear can be available on buses nor in any register or memory inside or outside the processor core. On case by case, for more flexibility, part of SALT™ can be embedded in a secure element or in a TEE.
MORE FUNCTIONNALITY, HIGHER SECURITY
Most of the IoT management tools are limited to authentication and right management. Algodone offers additional functions for measurement and control.
THE SALT™ ARCHITECTURE
SALT™ includes two key technology components: Secure DRM IP and Secure License Server
THE LICENSE SERVER
Algodone Secure License Server generates and manages encrypted licenses. The communication with the objects is achieved by exchanging license files.
THE DRM IP
It uses Root Of Trust to strongly authenticate and make sure that licensing is only activated for the intended device. It also controls the encrypted license to enable/disable device functionalities or features. The licenses are also used to return data to the license server.
