System and method for secure end-to-end electronic communication using a mutating table of entropy
The various implementations described herein include methods and systems for using mutatable privacy tables to secure electronic communications. A first electronic device obtains a first version of a privacy table and applies a predefined hashing algorithm to the first version of the privacy table to generate a second version of the privacy table. The first electronic device obtains a first message for transmission to a second electronic device that (i) has a copy of the first version of the privacy table and (ii) has access to the predefined hashing algorithm. The first electronic device generates a primary key based on the second version of the privacy table. The first electronic device encrypts the first message using the primary key to form an encrypted first message and transmits the encrypted first message and a version identifier for the second version of the privacy table to the second electronic device.
