Abstract (en)
[origin: WO2023046294A1] A method of establishing a secure channel between devices. The method includes at each of two devices generating a random variable, calculating a random function based on the random variable, generating a hash for a predetermined password, and generating a message including the hashed password and corresponding function. The method further includes, sending the generated message to the other device, and receiving the message generated by the other device, computing the random function of the other device based on the received message and the hashed password, and computing a transcript based on the ID of both devices, and the generated messages of both devices. The method further includes, generating, using a crypto hash function, session keys, such as an integration key, and an encoding key to establish a secure channel between devices. The method provides the secure channel between two devices with enhanced security and reduced communication and computational complexity.
