(Special technology allows to prevent reverse engineering and hacking microcontroller firmware)
There is the possibility of obtaining confidential information about the program executed by the microcontroller through the analysis of current consumption. For example, it is possible to narrow the secret encryption key search range for DES algorithm. This vulnerability is particularly critical in payment systems, electronic purses, access control systems.
The use of modern methods of protection of microprocessor systems of reading the current consumption is one of the main tasks in the development of microprocessor systems working with sensitive data. A cryptographic secure computing system that protects sensitive data from being read, and protection against breaking algorithm. Protection read current consumption is a promising method because it provides additional protection of confidential information by reading the electromagnetic radiation.
