Title: Innovations by Harry R. Rasmussen
Introduction
Harry R. Rasmussen is a notable inventor based in Tacoma, Washington. He holds a total of 14 patents, showcasing his significant contributions to the field of secure communications. His innovative methods and devices have advanced the way data is encrypted and transmitted over non-secure links.
Latest Patents
One of his latest patents is a method for ensuring secure communications between two stations. This method involves generating a session data encryption key (DEK) that is securely exchanged between the stations. The first portion of the DEK is randomly generated and encrypted using a key exchange key (KEK). This encrypted DEK is then transmitted along with an encrypted EDU ID number and a cyclic redundancy check (CRC) value. The receiving station decrypts the DEK and verifies the integrity of the communication before generating its own portion of the DEK. This process ensures that both stations can securely exchange data throughout their session.
Another significant patent by Rasmussen is an encryption/decryption apparatus with a non-accessible table of keys. This device manages encryption keys used in secure data exchanges. It includes a central processing unit (CPU) and a data encryption standard (DES) coprocessor, all embedded in a protective potting material. This design prevents unauthorized access to the stored data and program code, ensuring secure communications over non-secure links.
