CECPQ1
In cryptography, CECPQ1 is a post-quantum cipher developed by Google to make web browsers secure via Transport Layer Security (TLS).[1]
Details
CECPQ1 was designed to provide confidentiality even against an attacker who possesses a large quantum computer. It is a key-agreement algorithm plugged into TLS that combines X25519 and New Hope, a ring learning with errors primitive. Even if New Hope turns out to be breakable, the X25519 key-agreement will ensure that it provides at least the security of our existing connections.[1]
It is available in Google Chrome 54 beta.[2]
