Patent attributes
Disclosed herein are methods, systems, and processes to provide layered encryption to facilitate end to end communication. A user input is displayed in a user interface of an input device. A public/private key pair is determined based on a random number, a provisioned seed, or a physical unclonable function (PUF) provided by the input device. A previous public/private key pair is stored in a storage device associated with the input device using a recipient public key as an index. The user input is encrypted with the recipient pubic key. The derived public key is sent as a header followed by the encrypted user input to a host computing device.
