Encrypt without the Performance Tax
What if you didn’t have to make a performance trade-off? Intel Advanced Encryption Standard7 New Instructions (Intel AES-NI) is a set of seven new instructions in the Intel Xeon® processor 5600 series that eliminate the performance tax by speeding up parts of the AES algorithm encryption/decryption execution. It makes encryption practical, stronger, and more efficient for data in motion, in process, and at rest. Benefits of these hardware-based instruction set extensions include the following: Improved performance. Intel AES-NI can accelerate performance 3 to 10 times faster than a software-only AES solution.
Improved security. The new instructions help address recently discovered side-channel attacks on AES. Intel AES-NI instructions perform the decryption and encryption more completely at the hardware level without the need for software lookup tables that could be susceptible to snooping. Therefore using AES-NI can lower the risk of side-channel attacks. Multiple usage scenarios. Intel AES-NI can be used in any application that uses AES, including network, disk, and file encryption solutions.
7 The Advanced Encryption Standard (AES) is a popular encryption standard first adopted by the U.S. government in 2001. It is generally displacing the older, less secure Data Encryption Standard (DES) encryption algorithm and is now widely used to protect network traffic, personal data, and corporate IT infrastructures.
