Publication number: 20160323100Abstract: A key generation device generates an initial secret key, and a time update key at regular intervals, and transmits the initial secret key and the time update key to a terminal device. The terminal device utilizes the initial secret key, the time update key, and a private key generated by the terminal device itself to form a key group. The key group and a public key generated by the terminal device are used as a key pair to encrypt and decrypt data, give a digital signature, and verify digital signatures. The time update key includes a time period, and after the time period expires the time update key cannot be used by the terminal device to generate the key group. A data signature and encryption method is also provided.Type: ApplicationFiled: July 31, 2015Publication date: November 3, 2016Inventors: TUNG-TSO TSAI, JUNG-YI LIN, CHIH-YUAN CHUANG, CHIH-TE LU, PO-JEN HSU, SHU-YUAN CHANG

Publication number: 20160191240Abstract: A data encrypting and decrypting method which functions in an electronic device is activated when an application program is activated in the device. Data arising from user input is generated and a public and private key pair is also generated. The data is encrypted with the public key to obtain cryptographs and the cryptographs are sent to the application program. The method allows for decryption of the cryptographs with the private key to obtain the original data.Type: ApplicationFiled: September 8, 2015Publication date: June 30, 2016Inventors: CHIH-YUAN CHUANG, JUNG-YI LIN, PO-JEN HSU, CHIEN-MIN CHOU, CHIH-TE LU, SHU-YUAN CHANG
