"How Randomized Data Can Improve Our Security"

Technical devices have two essential units to process data: a processor and Random Access Memory (RAM). Since memory is much slower at providing data than the processor is at processing it, modern processors use a cache to function as a bridge between the two. This cache often has sensitive data, making it an attractive target for attackers. In collaboration with researchers from Japan, a group of scientists from Bochum, Germany, developed an innovative cipher that provides greater security than previous methods and is more efficient and faster. The idea is to use mathematical processes to randomize the data in the cache. This randomization in the Central Processing Unit's (CPU) cache can help stop attacks by preventing malicious actors from removing data from the cache. This article continues to discuss the research on a low-latency block cipher for secure cache-randomization.
