Method and system for the authorization management

A system for the authorization management of digital contents having at least one first electronic work environment to be used by an owner of an authorization and at least one second electronic work environment to be used by a user of the contents, the first work environment assigning the digital contents a defined scope of authorization, and where the digital contents in the second work environment assigned to the defined scope of authorization can only be used at the defined scope of authorizations, comprising:

• an encryptor on the first electronic work environment that encodes the digital contents to create an encoded contents;
• a decryptor on the second electronic work environment that decodes the encoded contents to create a decoded digital contents,
• wherein, the first electronic work environment or the second electronic work environment further comprise a reference list of a plurality of scopes of authorization, including the defined scope of authorization, each scope of authorization corresponding to a level of functionality for the digital contents,
• each scope of authorization having a unique associated encryption and decryption, usable by the encryptor and decryptor, respectively, enabling the digital contents in the first electronic work environment to be encoded with the encryption corresponding to a particular scope of authorization selected from the reference list and the encoded contents are decodable by the decryption associated with the defined scope of authorization with the second electronic work environment, where the digital contents on the second electronic work environment can only be used at the scope of authorizations corresponding to the decryption and enabling the associated level of functionality.

A method for the authorization of digital contents between a first electronic work environment and a second electronic work environment, wherein the second electronic work environment comprises a computer configured for technical system modeling and the digital contents represent simulation models, comprising:

• storing a reference list in the second electronic work environment that identifies a plurality of scopes of authorizations and provides a unique decryption associated with each such scope of authorization;
• receiving an encrypted digital content at the second electronic work environment;
• decrypting the encrypted digital content at the second electronic work environment using one of the unique decryptions from the reference list to create a decrypted digital content;
• using the decrypted digital content on the second electronic work environment to simulate a technical system, wherein the use of the decrypted digital content is restricted by the scope of authorization associated with the one unique decryption on the reference list that was used for decrypting.
