Latest Patents

One of his latest patents is titled "Block encryption security for integrated microcontroller and external memory system." This invention describes a secure microcontroller system that includes an integrated cache sub-system, a crypto-engine, a buffer sub-system, and external memory. The system employs block encryption methods to protect the content communicated between the microcontroller and external memory while maintaining real-time performance. Additionally, it features a user-configurable memory write policy that allows for the selection of memory write protocols to balance data coherency and system performance.

Another significant patent is "Encryption-based security protection for processors." This patent outlines methods and systems that enhance processor security through the implementation of block encryption. The block may consist of multiple instructions and operations executed by the processor. Once a block-wide encrypted buffer is filled from an external memory source, it can be decrypted using an encryption algorithm, such as the Data Encryption Standard (DES). The decrypted block is then forwarded to a decrypted buffer and can be moved into a cache for efficient instruction retrieval.
