Latest Patents

One of his latest patents is a "Full-text fuzzy search method for similar-form Chinese characters in ciphertext domain." This invention discloses a method that enables fuzzy searches in the Chinese ciphertext domain using a symmetric searchable encryption scheme and an inverted index structure. It supports fuzzy searches on Chinese characters with similar glyphs while ensuring that the search results are ordered. The invention utilizes a distributed search engine, Lucene, and a Chinese word segmentator, IKAnalyzer, to perform full-text word segmentation on documents. It constructs a plaintext inverted index comprising similar-form Chinese characters from a library of 3,755 commonly used characters. The method also emphasizes security by constructing an encrypted chain form for each keyword in the plaintext inverted index, utilizing a B+ tree structure to enhance search speed. This invention successfully realizes a fuzzy search in a Chinese full-text ciphertext domain on a semi-trusted cloud server without false or missed detections.

Another notable patent is the "Online/offline signature system and method based on multivariate cryptography." This system includes a key distribution center (KDC) and a signature end. The KDC comprises a key generating module, an offline signature module, and a verification module. The signature end features an online signature module and a verification module. The key generating module creates a temporary signature for online use, which is then stored in a sensor node. The online signature module generates a signature for specific messages, while the verification module determines the validity of the signature through a processor and a public key transformation component.
