The object of the present invention is to safeguard the authenticity and integrity of real-time data in a distributed real-time computer system. The present invention considers other requirements of real-time data processing, such as the timeliness of real-time data transmission and limited resource availability. Frequent modification of an asymmetric key pair hinders intruders from cracking a key before its validity has expired. The present method can also be extended to safeguard the confidentiality of real-time data. It can be implemented efficiently on a multiprocessor system-on-chip (MPSoC).
