CloudFlare crypto gets faster on old mobes
Popular denial of service deflection platform CloudFlare is deploying new speedy cipher suites previously championed by Google, maths boffin Nick Sullivan says.
The ChaCha-Poly1305 cipher is three times faster than the resource heavy AES-128-GCM cipher and was not subject to attacks against RC4, Sullivan (@grittygrease) says, meaning things will speed on CloudFlare for mobes.
“Spending less time on decryption means faster page rendering and better battery life,” Sullivan says. “Although the cipher part of TLS may not be the biggest source of battery consumption (the handshake is more expensive ), spending fewer CPU cycles on encryption saves battery life, especially on large files.
