Somewhat off-topic, but Google took ChaCha20/Poly1305 live. http://googleonlinesecurity.blogspot.com/2014/04/speeding-up-and-strengthening-https.html
Earlier this year, we deployed a new TLS cipher suite in Chrome that operates three times faster than AES-GCM on devices that don’t have AES hardware acceleration, including most Android phones, wearable devices such as Google Glass and older computers. This improves user experience, reducing latency and saving battery life by cutting down the amount of time spent encrypting and decrypting data. To make this happen, Adam Langley, Wan-Teh Chang, Ben Laurie and I began implementing new algorithms -- ChaCha 20 for symmetric encryption and Poly1305 for authentication -- in OpenSSL and NSS in March 2013. It was a complex effort that required implementing a new abstraction layer in OpenSSL in order to support the Authenticated Encryption with Associated Data (AEAD) encryption mode properly. AEAD enables encryption and authentication to happen concurrently, making it easier to use and optimize than older, commonly-used modes such as CBC. Moreover, recent attacks against RC4 and CBC also prompted us to make this change. ... _______________________________________________ cryptography mailing list cryptography@randombit.net http://lists.randombit.net/mailman/listinfo/cryptography
