Latest Patents

Frezza's latest innovations include two notable patents that demonstrate his expertise in communication security.

The first patent is for a "Bootstrap Channel Security Arrangement for Communication Network." This invention presents an apparatus and method that allows for on-line modification and upgrading of terminal software while preserving the integrity of the communication between a service provider and a subscriber. The process involves software being downloaded via a booter channel, where a subscriber terminal initiates communication with the network to receive and store the downloaded booter data. A checksum is computed from this data, ensuring that control of the terminal transfers to the downloaded software only when the checksum is validated.

His second patent focuses on the "Security Arrangement for Downloadable Cable Television Converters." This invention provides a method and apparatus to prevent unauthorized programming viewing via downloadable cable television converters. By computing a booter checksum from a downloaded image and comparing it with an extracted valid checksum from a scrambled program signal, this innovation helps ensure that a descrambler is only enabled when the checksums match. This effectively blocks potential pirates from using false booter images, thereby maintaining the integrity of the cable converter.
