wolfSSL Increases Crypto Performance

Share Article

wolfSSL uses Intel's extended instructions to accelerate crypto algorithms for IoT.

wolfSSL, an open source SSL/TLS security company has optimized the wolfSSL Transport Layer Security (TLS) library on 5th generation Intel® Core™ processors. With the inclusion of Intel’s extended instructions developers can use the wolfSSL libraries for applications on many devices, including embedded technologies. The resulting improvements mean end users will see enhanced speed and security with reduced power consumption across a wide range of devices including Internet of Things.

While cryptography arithmetic is often larger than many systems can support, even for 64-bit systems, by using Intel's AVX1/2 SIMD instructions, developers can make use of the new optimizations to whittle down the compute needed, thereby reducing complexity and increasing performance. wolfSSL benchmarks show the wolfSSL secure hash algorithms are now significantly faster. The Advanced Vector Extensions perform multiple word operations with a single instruction (in parallel) to provide this boost in speed. wolfSSL also integrated Intel® Secure Key Technology (https://software.intel.com/en-us/blogs/2012/05/14/what-is-intelr-secure-key-technology ) to provide a high-quality, high-performance entropy source and random number generator.

Larry Stefonic, CEO of wolfSSL, adds "Handcrafting the world's best crypto is our nature, so it is great to leverage Intel's fantastic engineering support for the primitives to enhance our product. Our wolfSSL customers will enjoy better performance as a result of these software optimizations on 5th generation Intel Core processors.”

More detail on the performance can be found on the wolfSSL blog (http://www.yassl.com/yaSSL/Blog/Entries/2015/4/16_Intels_Extended_Instructions_Accelerates_Hash_Algorithms.html) while developers can download the latest release of wolfSSL on their website https://wolfssl.com/yaSSL/download/downloadForm.php.
