Abstract
An arrangement for establishing a digital crypto group includes a cryptographic engine configured to produce cryptoproducts from given input data. The cryptographic engine responds to receiving, through a secure transport mechanism, requests containing user identifiers by producing a cryptoproduct. It also responds to receiving, through the secure transport mechanism, a subsequent second request containing one of the plurality of user identifiers by transmitting the cryptoproduct through the secure transport mechanism. The cryptoproduct is a digital crypto group that contains the plurality of user identifiers and a common cryptographic key for use in symmetric cryptography between users identified by the plurality of user identifiers and/or user-specific and user-identifier-related public keys for use in asymmetric cryptography in communications between users identified by the plurality of user identifiers.
