More efficient by isolating software components.
Efficient Protection of Sensitive Data
Max Planck Gessellschaft
September 3, 2019
Researchers at the Max Planck Institute for Software Systems in Germany have developed a new technology to isolate software components from each other. ERIM allows sensitive data to be protected from hackers when the data is processed by online services. The method has up to five times less computational overhead than the previous best isolation technology, making it more practical for online services to use. The researchers combined the Memory Protection Keys (MPK) hardware feature with instruction rewriting to create an environment in which an attacker is no longer able to get around the "walls" between software components. Said the Institute’s Peter Druschel, “Software developers are in a permanent race against time and cyber criminals, but data protection still has to be practical. This sometimes calls for systematic but unconventional approaches, like the one we pursued with ERIM.” .... '
