Protecting Firefox Data with Content Signatures

Thursday, January 18, 2018 - 1:30 pm2:00 pm

Julien Vehent, Firefox Operations Security Lead at Mozilla


Guaranteeing the integrity of data sent from web services to Firefox is difficult due to transport intermediaries that have the ability to modify data on-the-fly, and the risk of a web server compromise sending fraudulent data to end-users. Content signature is a new signing protocol built into Firefox to protect the integrity of the data exchanged between Mozilla and millions of Firefox installations in the wild.
