Latest Patents
One of Le Guan's latest patents is a key protecting method and apparatus. This innovation provides a method for key protection by ensuring that each core of a multi-core processor has one symmetric master key. It dynamically obtains the plaintext private key of the asymmetric algorithm through a decryption operation. By utilizing Intel TSX, this method ensures that the private key and intermediate variables are stored in the cache of the operation core, thereby preventing attackers from accessing the private key from physical memory.
Another notable patent is the multi-core processor-based key protection method and system. This system involves setting up an Operating System (OS) that supports Symmetric Multi-Processing (SMP) on a multi-core processor. One core is dedicated to cryptographic operations, prohibiting it from running other OS processes. The private key and intermediate variables are stored in a cache exclusively occupied by this cryptographic operation core, enhancing the security of public-key cryptographic operations.
