METHOD AND ARCHITECTURE FOR SECURING REAL-TIME DATA

摘要

The aim of the invention is to secure the authenticity and integrity of real-time data in a distributed real-time computer system. Said aim is achieved by a method that takes into account the special requirements of real-time data processing such as the timeliness of real-time data transmission and the limited availability of resources. Frequently changing an asymmetrical pair of keys prevents hackers from cracking a key before said key is no longer valid. Said method can also be extended to ensure confidentiality of real-time data and can likewise be efficiently implemented on a multiprocessor system-on-chip (MPSoC).
