A security technique to fool would-be cyber attackers

Researchers at MIT have developed a method that improves computer security against memory timing side-channel attacks without sacrificing computation speed. The technique, named DAGguise, allows memory sharing to continue but ‘shapes’ a program’s memory requests into a predefined pattern, ultimately increasing computation speed by 12% over existing security schemes. This approach could potentially be adapted to a variety of side-channel attacks that target shared computing resources.
