چکیده (انگلیسی):

Real-time data packet sources are required to remain robust against different security threats. This study
proposes a real-time secure scheduling strategy for data transmission to enhance the communication
throughput and reduce the overheads. The proposed system combines real-time scheduling with security
service enhancement, error detection and realtime scheduler based on EDF algorithm using uc/os-II real
time operating system, implemented on cortex M3 processor. The scheduling unit uses central queue
management model and the security enhancement scheme adopts a blowfish encryption mechanism.
