Abstract:
In a method for managing access to a secure content-part of a PPCD following introduction of the PPCD into a workflow among a plurality of workflow participants, in a secure content manager, from a workflow participant of the plurality of workflow participants, a key-map file for a subsequent workflow participant that is to receive the key-map file is received, wherein the key-map file comprises a set of keys to enable the subsequent workflow participant to access the content-part in the PPCD. In addition, authenticity of the received key-map file is verified, the subsequent workflow participant to receive the PPCD is identified and authenticated, a public key of the subsequent workflow participant is accessed, the key map file or a symmetric key used to encrypt the key-map file prior to receipt of the key-map file by the secure content manager is encrypted using the public key of the subsequent workflow participant, and the encrypted key-map file is sent to the subsequent workflow participant.
