Latest Patents

One of Patrick's notable patents is focused on "Protecting secret state from memory attacks." This technology outlines methods to prevent classes of memory attacks, including cold boot attacks, DMA attacks, and bus monitoring attacks. The patent describes how secret states, such as an AES key and an AES round block, are maintained in on-SoC secure storage, like a cache. The corresponding cache locations are locked to prevent eviction to unsecure storage. Additionally, AES tables are accessed only in the on-SoC secure storage to prevent access patterns from being observed. The patent also details a secure method for preparing for an interrupt-based context switch during AES round computations and securely resuming from a context switch without needing to repeat any already completed rounds of computations.
