Anti-quantum computing vehicle-mounted network identity authentication system and method based on secret sharing and multiple mobile devices

Abstract

The invention discloses an anti-quantum computing vehicle-mounted network identity authentication system and method based on secret sharing and multiple mobile devices. The system comprises a plurality of mobile devices, a routing device and a server, a single server is provided with a plurality of routing devices, a single routing device is provided with a plurality of mobile devices, and the same user corresponds to one routing device and a plurality of mobile devices belonging to the routing device. According to the method, the ID and the secret key of the user are secretly shared and distributed to the routing device and the secret key cards of the plurality of mobile devices, so that malicious information acquisition caused by violent cracking of the secret key cards is avoided, and information loss caused by losing of the secret key cards is also avoided; each piece of mobile equipment and the corresponding routing device must be subjected to signature authentication to completethe whole signature, so that all rights and interests of the corresponding account are greatly protected; the undisclosed user public key is added into the signature process of the server, so that thesignature can resist the attack of quantum computing without additional encryption protection.

Description

technical field [0001] The invention relates to the field of identity authentication, in particular to a quantum computing-resistant vehicle network identity authentication system and method based on secret sharing and multiple mobile devices. Background technique [0002] Identity authentication is the basic technology to achieve information security. The system checks the user's identity to confirm whether the user has access and use rights to certain resources, and can also perform identity authentication between systems. [0003] The in-vehicle network is formed by connecting the mobile device held by the user to the in-vehicle routing device through a short-distance connection, and the in-vehicle routing device is connected to the server through the network. The actual specific form of mobile devices can be car keys, mobile communication terminals (such as mobile phones, etc.), wearable devices (such as Bluetooth headsets, smart glasses, smart watches, etc.), IC cards, ...

AI Technical Summary

Problems solved by technology

[0009] 2. After the key card is lost or stolen, it may be used directly and cause damage to the rights and interests corresponding to the user account

For example, transfer all the rights and interests of the user account, resulting in the theft of rights and interests;

[0010] 3. The anti-quantum computing ability of the existing digital signature is not high, and the private key of the signature may be calculated. In order to make the digital signature anti-quantum computing ability, the digital signature must be encrypted, which increases the calculation amount of the digital signature;

[0011] 4. The ID of the existing network communication subject is exposed in the network, and the security of user privacy is not high
