Method of resisting decryption attempts by quantum artificial intelligence

Abstract

The present invention relates to a novel method for protecting encrypted information against decryption attempts by quantum artificial intelligence. The invention is based on the prior modification of the encrypted information so that multiple decryption attempts result in solutions plausible to quantum artificial intelligence. Thus, said artificial intelligence can generate a large number of plausible solutions without being able to determine which one is correct. Abstract figure: Fig. 1

Description

Title of the invention: Method of resisting decryption attempts by quantum artificial intelligence Technical field

[0001] The invention is a means of securing a set of data. Prior art

[0002] We know of methods for verifying a file by an element controlling its integrity, a hash, a checksum or a digital signature for example.

[0003] Data encryption methods are also known.

[0004] Data verification devices are also known which consist of providing a file containing the data in question with such a control element.

[0005] Such devices are known in which all or part of a file or its access link is represented by a string of numeric or alphanumeric characters and it is known how to sign such strings to guarantee their origin and integrity. It is also known how to represent such strings by barcodes.

[0006] Finally, we know of a method of giving a person a digital identity by providing them with a signed file containing their photograph and all the details of their identity. Technical problem

[0007] Quantum computing and artificial intelligence now make it possible to decrypt encrypted files, particularly by brute force.

[0008] The objective of the present invention is to resist attempts to decrypt files by quantum artificial intelligence. Brief description of the drawings

[0009] The invention will be well understood, and other objects, advantages and characteristics thereof will appear more clearly on reading the description which follows, which is illustrated by [Fig.l].

[0010] [Fig.l] is a diagram showing a procedure for reading and verifying a digital file according to the invention. The receiver reads the signed barcode containing the address of a digital file on a data server and an integrity control element of this digital file. It verifies this barcode by its electronic signature by contacting, if necessary, a signature server, and then transmits the address of the digital file to the data server containing the digital file. It receives the digital file in return and verifies it by the integrity control element. Presentation of the invention

[0011] The invention is a method of encrypting a set of data comprising the following steps: 1. modify a computer file containing all or part of said data set and encrypt it to obtain a file known as an unintelligible file, 2. calculating a message called mes sage-meaningful containing the data necessary to decrypt said unintelligible file and determine the validity of one of the decrypted solutions, characterized in that said modification is such that several decryption attempts can result in a plurality of plausible solutions Detailed description of the invention

[0012] The present invention relates to a novel method for protecting a data set presented in the form of encrypted information against decryption attempts by a quantum artificial intelligence. The invention is based on the prior modification of the encrypted information so that several decryption attempts result in plausible solutions for a quantum artificial intelligence. Thus, said artificial intelligence can generate a large number of plausible solutions without being able to determine which one is correct.

[0013] The protected information includes, in addition to this file, called the unintelligible-file, an additional element, called the significant-message, which contains the data necessary to decrypt the unintelligible-file, verify the integrity of its content and determine the validity of the decryption solution. This significant-message may take the form of a character string, a barcode or an internet link. It includes references or links to the unintelligible-file, including several links to distinct parts of the file that may be deposited at different addresses, as well as a decryption key and information allowing the correct version of the decrypted file to be selected. The significant-message may also be digitally signed to ensure its validity by a non-repudiation check.

[0014] In the case where the decryption of the file can only be carried out online, the message-signifier is kept confidential by a secure computer, which uses it to provide the protected information or verify its conformity with the information provided by the person seeking verification. A limited number of attempts is allowed in order to prevent brute force attacks. This is made possible by requiring one of the plausible solutions, and / or strong identification and proof of permission from the person or computer seeking validation.

[0015] The information protection method according to the present invention can be implemented by any operator. The latter can transmit the unintelligible file by any means, while the meaningful message can be sent through a communication channel. separate communication if local decryption is desired. For example, the meaningful message may be delivered to the user in the form of a text message or a physical document (e.g., a barcode printed on an identification document), while the unintelligible file may be made available via email or a download link.

[0016] The signifier message may also contain non-confidential information in clear text, advantageously signed, such as the title of the protected information or some of its characteristics. This makes it possible to sign and communicate identities or certificates to third parties, who may, if necessary, obtain additional information, such as an identity photo or a certified copy of a contract, by submitting the signifier message to the competent server.

[0017] The method described in this invention can be applied to all forms of texts, such as medical prescriptions, medical examination reports, expert reports, contracts, etc. It extends to all types of files requiring confidentiality.

[0018] When the meaningful message is communicated, it is also important to prevent a quantum computer from brute-force decrypting the part of this message that allows finding the original version of the unintelligible file. The proposed solution consists of responding only to requests containing one of the plausible decrypted versions of the unintelligible file and / or implementing a strong identification system, thus effectively limiting the number of authorized attempts.

[0019] The method described in the present invention represents a significant advance in the field of encryption, making data impenetrable to decryption attempts by the most sophisticated quantum artificial intelligence systems. Applications

[0020] The main applications are - digital identity, the holder of which may only keep a signed meaningful message, in printed or electronic form, to identify himself, - medical prescriptions, certificates and attestations of all kinds, contracts, purchase orders, invoices, etc. which can be easily authenticated by their recipients, - music or video on demand services, newspapers and magazines, video games, means of controlling connected objects, - and generally the securing of any type of large or sensitive data.
