Physicists propose autferroic materials for faster microchip encryption chips
A team of physicists co-led by researchers at Rice University and Southeast University has proposed a new class of materials called autferroics to improve security chip performance.
New material blueprint for encryption
The research team published their findings in the journal Physical Review Letters. They describe how these autferroic materials could act as a theoretical solution for generating unpredictable numbers needed for secure transactions. This approach aims to overcome existing limitations in current random number generators without sacrificing signal quality.
Speed and signal trade-off solved
Standard security devices often trigger microscopic jumps too slowly, which can cause systems to lag or become vulnerable to hacking. Engineers previously tried to fix this by shrinking components or applying magnetic forces, but those methods degraded the signal and caused data-reading errors. The proposed autferroics could speed up physical true random number generators thousands of times while keeping signals clear.
