CECPQ1 - Definition from the Hotspot Shield Glossary

CECPQ1 is a form of cipher created by Google with the express aim of increasing the security of web browsers via TLS (Transport Layer Security).

The cipher was designed to maintain a level of confidentiality even against the most powerful and advanced hackers with equipment like quantum computers. The cipher is formed from a key-agreement algorithm that is connected to TLS and combines X25519 and NewHope which are two forms of cryptography. The cipher provides a fail-safe in that if he NewHope cipher can be broken, the X25519 part of the algorithm will ensure that some form of security will still be provided. CECPQ1 is available in the web browser Google Chrome.
