The CS5331 and CS5332 OCB-AES Simplex EncrypTIon/DecrypTIon cores1 are designed to provide simultaneousdata privacy and authenTIcity in digital broadband, wireless, and mulTImedia systems. These high performanceapplication specific silicon cores combine the efficiency of OCB authentication with the high security of Rijndaelencryption algorithms, offering a state-of-the-art authenticated-encryption scheme. The CS5331 and CS5332cores provide the high security functionality of OCB-AES for different applications based on the importance ofrequired speed and size. The CS5331 is a Compact OCB-AES core and is suitable for applications like PDAs andwireless LANs where small size is crucial. The CS5332 is a High Speed OCB-AES core and is appropriate forapplications such as wireless LAN high speed network servers where speed of operation is more critical. TheAmphion CS5331 and CS5332 cores are available in both ASIC and programmable logic versions that have beenhand crafted by Amphion to deliver high performance while minimizing power consumption and silicon area.
