Data encryption using an external arguments encryption algorithm: it is an encryption system which uses symmetrical secret key algorithms but the operating arguments thereof and/or the actual encryption/decryption algorithm is/are unknown before use and is/are created at the time of encryption and then destroyed but is/are stored in an independent or non-independent computer or non-computer system (paper, human memory, other non-computer media, etc.) of the system which encrypts or decrypts the data/message for the subsequent reuse thereof at the time of decryption. It will be used as a client/server system, wherein the client uses a set of variable arguments and/or the actual algorithm which is/are stored, however, outside the actual client in the server. The operating arguments and/or the actual encryption/decryption algorithm may be generated/used both by the client and by the server but is/are stored exclusively in the server (whether this is a computer or non-computer storage system) in a manner independent of the client, which makes it possible to control and/or limit the use thereof. |
