This paper examines the impact of the multibuffer enhancements to OpenSSL* on the Intel® Xeon® processor E5 v3 family when performing AES block encryption in CBC mode. It focuses on the performance gains seen by the Apache* web server when managing a large number of simultaneous HTTPS requests using the AES128-SHA and AES128-SHA256 ciphers, and how they stack up against the more modern AES128-GCM-SHA256 cipher.
This case study examines the architectural improvements made to the Intel® Xeon® E5 v3 processor family in order to improve the performance of the Galois/Counter Mode of AES block encryption. It looks at the impact of these improvements on the nginx* web server when backed by the OpenSSL* SSL/TLS library. With this new generation of Xeon processors, web servers can obtain significant increases in maximum throughput by switching from AES in CBC mode with HMAC+SHA1 digests to AES-GCM.
Intel® QuickAssist Technology Introduction
Intel® QuickAssist Technology accelerates and compresses cryptographic workloads by offloading the data to hardware capable of optimizing those functions. This makes it easier for developers to integrate built-in cryptographic accelerators into network and security applications.
This blog outlines the steps needed to integrate Intel’s AES-NI instructions into an Android app via the OpenSSL library. By following the procedures here, you’ll be able to build a JNI application that benefits from AES-NI acceleration.
While Intel did not release an Intel® vProTM Technology desktop with ME (Intel® Manageability Engine) Firmware v10, the later versions of firmware are backwards compatible as early as Intel® 7 series chipsets (ME 8.x originally).
