This paper presents a method of hardening the 8051 micro-controller, able to assure reliable operation in the presence of bit flips caused by radiation. Aiming at avoiding such faults in the 8051 micro-controller, Hamming code protection was used in its SRAM memory and registers. A VHDL code has been used for this hamming code protection. Keywords—Radiation, hardening, bitflip, hamming code.

Considering the extensive usage of electronic systems in Spacecraft and harsh radiation environment in the Space, radiation effects on electronic systems and development of radiation hardening electronic systems have been a topic of research. Researchers are trying to solve this problem at various abstraction levels, starting from fabrication technology to packaging and at system level. This pa...

Microsoft Windows systems have been the favourite target of viruses, worms and spyware in recent years. Through a kernel level process, we can secure WindowsTMprocesses by running them in a form of a sandbox. These sandboxes are configured to only allow a subset of rights to be granted to the process, therefore limiting the ability of a rogue process or a compromised process to inflict damage o...
