Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A computing device, comprising:
one or more processors; and
memory coupled to the one or more processors, the memory storing one or more programs configured to be executed by the one or more processors, the one or more programs including instructions for:
storing a privacy table at the computing device, the privacy table comprising random numbers;
transmitting the privacy table to an electronic device over an encrypted channel, wherein the electronic device is distinct from the computing device;
receiving a first message for transmission to the electronic device;
generating a map based on the privacy table, the map including instructions on how to use the privacy table to generate a primary key;
generating the primary key based on the map and the privacy table;
encrypting the first message using the primary key to form an encrypted first message;
transmitting the map and the encrypted first message to the electronic device, enabling the electronic device to decrypt the encrypted first message by:
recreating the primary key based on the map and the privacy table; and
decrypting the encrypted first message using the recreated primary keys;

receiving a second message for transmission to the electronic device;
generating a new map, which is distinct from the map;

generating a new primary key based on the new map and the privacy table, wherein the new primary key is distinct from the primary key;
encrypting the second message using the new primary key to form an encrypted second message; and
transmitting the new map and the encrypted second message to the electronic device, enabling the electronic device to decrypt the encrypted second message by:
recreating the new primary key based on the new map and the privacy table; and
decrypting the encrypted second message using the recreated new primary key.
