Abstract (en)

[origin: WO0049767A1] A method for creating a global unambiguous identifier for predetermined data structures and for storing identifiers created. In the method, an unambiguous identifier is created from a key and/or keys associated with an encryption and/or signing procedure and/or from key holder information and/or other information. From the identifier, an unambiguous hash code is generated using e.g. a hash function. The hash codes thus generated are stored in a centralized place so that each hash code is unambiguously associated with a given juridical person and a given key pair. The hash code can be used e.g. as a part of encrypted messages sent by a mobile station in a mobile communication system so that the user can infer from the identifier how the message can be decrypted into plain language.
