Data encryption using an external arguments encryption algorithm

摘要

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.

1. A computer-implemented method of decrypting an original encrypted data item from a client encryption system using a client decryption system, the method comprising:
receiving from the client encryption system, by the client decryption system, both the original encrypted data item and an identifier of External Arguments Encryption Algorithm (EAEA) parameters configured for the original encrypted data item; logging into an EAEA server wherein the EAEA parameters of encryption or decryption configured for at least the original encrypted data item are stored but wherein the original encrypted data item is not stored at the EAEA server; obtaining, by the client decryption system, computer-executable decryption instructions; and executing, by the client decryption system, the computer-executable decryption instructions using the EAEA parameters from the EAEA server upon the original encrypted data item so that the original encrypted data item becomes a decrypted version of the original encrypted data item without keeping the EAEA parameters so that the EAEA parameters reside solely at the EAEA server and so that any copies of the original encrypted data item are thereby made invulnerable to any brute force decryption attempt.
