Encryption Mechanism for System-on-Chip Using MiniDES Algorithm With Digital Signature for Secure Communication of Embedded Real Time Applications
System-on-Chip applications have been widen to various public, private, government and social communication systems for handling security and trust as a systems for mission critical and e-government. Most mission critical and embedded real time applications run on System -on -Chip. SoCs will have limited resources, processing ability and rigid power constraints therefore, SoCs becomes a holdup when it comes to handling the complex and large footprint software. The saRTL is standalone Real Time Linux operating system with small footprint and having hard real time features. The bare kernel of saRTL is approximately 200KB only. Therefore, using saRTL is a better option for SoC based applications.
