Title: Innovations of Wing Pan Leung
Introduction
Wing Pan Leung is an accomplished inventor based in Hong Kong, CN. He holds a total of 3 patents that showcase his expertise in encryption and content distribution technologies. His innovative approaches have contributed significantly to the fields of data security and efficient content delivery.
Latest Patents
One of Wing Pan Leung's latest patents is titled "Partial CipherText updates using variable-length segments delineated by pattern matching and encrypted by fixed-length blocks." This invention introduces a re-encryptor that compares hashed digests of updated segments with original segments to identify changes that require re-encryption. By utilizing a new initialization vector for each changed segment, the invention reduces the amount of cipher text altered by a single update to just a segment. This method enhances transmission efficiency to remote encrypted storage by limiting the disruption of cipher text during updates.
Another notable patent is the "System and method for content distribution with broadcast encryption." This method involves an encryption process that computes ciphertext using a differential ciphertext generation method. The efficiency of the system is improved by reusing previously preserved computational results whenever the subscriber set changes. Additionally, the decryption process reconstructs the encryption secret used for decrypting the content, employing a wide window point addition method to enhance efficiency.
