Cryptographic key generating method for encrypted digital communication between communication devices, involves converting end product address of communication device into part of key, and utilizing address for key agreement
Cryptographic key generating method for encrypted digital communication between communication devices, involves converting end product address of communication device into part of key, and utilizing address for key agreement
The method involves converting an end product address of a communication device (500) into a part of a cryptographic key by direct or indirect application of an inversion function of a non-returnable function with a falling board. The cryptographic key is public or private. The end product address is utilized for key arrangement, and inverse function of the non-returnable function is computation of radical in a circle, where the non-returnable function represents exponentials in the circle. Independent claims are also included for the following: (1) a device for generating a cryptographic key (2) a roaming device for executing a procedure for key agreement (3) a digital data carrier comprising instruction for executing a procedure for key agreement.
