Latest Patents

Wenhui Cao holds a patent for a "Cache securing method and device capable of resisting side channel attack." This invention presents a method and device designed to enhance the security of cache memory. The innovation involves the incorporation of an allocator identifier (ALLOCATOR) field into each cache entry. This field is filled with the identifier of the software domain running on the processor at the time of entry allocation. The mechanism ensures that a cache entry can only be accessed if the current software domain's identifier matches the ALLOCATOR field. If the entry is invalid or its ALLOCATOR matches the current identifier, it is replaced directly; otherwise, the cache is completely emptied, thereby providing robust protection against potential side channel attacks.
