Abstract

Method and communication system for permitting access to a network via an access point, wherein the method comprises determining, at a first node of the communication system, at least one identifier of the access point. Using a predetermined encrypting function and the determined at least one identifier of the access point, access credentials are encrypted in such a way that the at least one identifier of the access point is required in order to decrypt the encrypted access credentials. The access credentials are for accessing the network via the access point. The encrypted access credentials are provided over the communication system to a second node of the communication system, and the second node determines the at least one identifier of the access point by communicating with the access point. The second node uses the determined at least one identifier of the access point to decrypt the encrypted access credentials using a predetermined decrypting function which corresponds to the predetermined encrypting function, and the second node uses the decrypted access credentials to access the network via the access point.
