  • Session protocol for backward security between paired devices
    Patent number: 10652736
    Abstract: Some embodiments provide a method for establishing a secured session with backward security between a first device and a second device. In some embodiments, the method establishes a communication session between the first and second devices using shared keys stored at the first and second devices. The method exchanges encrypted data between the first and second devices as a part of the communication session. The method, upon completion of the communication session, modifies the shared key at the first device in a predictable way. The shared key is modified at the second device in the same predictable way. The method then stores the modified shared key at the first device. The modified shared key cannot be used to decrypt any portion of the encrypted data of the current and previous communication sessions.
