Latest Patents

Jiguo Yu holds a patent for an "Attribute-based encryption (ABE) method with multiple tracing attribute authorities for cloud-assisted internet-of-things (IOT)." This method involves a central authority performing system initialization to generate public parameters, which are then disclosed. Each attribute authority initializes to generate a key pair and discloses a public key. A data owner performs symmetric encryption on plaintext data and applies ABE on a symmetric key based on a hidden access structure. The process includes generating an integrity verification value and requesting a decryption key from the attribute authority based on the user's attributes. The data user restores the access structure and generates an outsourcing decryption key, which is sent to a cloud storage center for semi-decryption. The cloud storage center generates a semi-decrypted ciphertext and feeds it back to the data user, who then fully decrypts it using a private decryption key. This innovative approach enhances the security and efficiency of data management in IoT environments.
