METHOD AND SYSTEM IN A DIGITAL WIRELESS DATA COMMUNICATION NETWORK FOR ARRANGING DATA ENCRYPTION AND CORRESPONDING SERVER

摘要

The invention concerns a method and system in a digital wireless data communication network for arranging data encryption as one-time pad encryption. The data communication network includes at least two terminal equipment, which are used to manage a set of indexed encryption keys and of these the first terminal equipment is at least a transmitter and the second terminal equipment is at least a receiver. Besides the encrypted data, the said encryption key index is transmitted to the receiving terminal equipment. The data communication network also includes a special server terminal equipment, which is arranged to manage and distribute a set of indexed encryption keys to the terminal equipment. The invention also concerns a corresponding server terminal equipment.
