Latest Patents

Chiou holds a patent for a "DES cipher processor for full duplex interleaving encryption/decryption service." This full duplex DES cipher processor (DCP) is designed to execute sixteen rounds of data encryption standard (DES) operations in four encryption modes and four decryption modes. The modes include Electronic Code Book (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), and Output Feedback (OFB) for both encryption and decryption. The DCP consists of an I/O unit, an IV/key storage unit, a control unit, and an algorithm unit. The algorithm unit is responsible for encrypting and decrypting incoming text messages. It features a crypto engine that allows for alternating encryption and decryption using the same engine. This design is particularly efficient for communication services like T1, E1, and V.35, where the algorithm unit's operation time is significantly shorter than the data I/O time. The full duplex operation is achieved by storing interim results of the DES encryption in a cipher text buffer (CTB) and decryption results in a plain text buffer (PTB). The DCP has two ports, one dedicated to encrypting and the other to decrypting, and it can also be utilized for single port simplex or dual port simplex applications. Chiou's innovative work has resulted in 1 patent.
