A new type of anti-peeping light-emitting warning optical puf

Abstract

The invention discloses a novel anti-snooping luminous warning optical PUF. The novel anti-snooping luminous warning optical PUF structurally comprises a substrate, an optical PUF dielectric layer growing on the substrate, a long afterglow luminescent material capable of being embedded in the substrate or the optical PUF dielectric layer, and a non-transparent box for packaging the substrate, the optical PUF dielectric layer and the long afterglow luminescent material therein. According to the novel anti-snooping luminous warning optical PUF, the long afterglow luminescent material added into a conventional optical PUF structure still can continuously emit light for a long time after the material is irradiated through a light source for a short time and the light source is turned off, and the light emitting behavior is utilized as a basis for judging whether the PUF is snooped or not, so that the PUF is endowed with an anti-snooping luminous warning function and the defect that a general optical PUF cannot judge whether excitation-response pairs of the optical PUF are snooped by an enemy or not is overcome; the PUF has the anti-snooping luminous warning function, so that the security of the optical PUF is ensured; and therefore, the novel anti-snooping luminous warning optical PUF has true practicality and can be widely applied to quantum authentication and quantum key distribution.

Description

technical field [0001] The invention relates to the security field based on PUF, in particular to a novel anti-snooping luminescent warning optical PUF suitable for IP protection, system authentication, trusted computing, secret key generation and other fields. Background technique [0002] In recent years, with the rapid development of informatization and the Internet of Things, identity authentication has become an indispensable key link in daily life. However, bank cards, credit cards, ID cards and other authentication card information are leaked or stolen by hackers, illegal duplication and other incidents occur frequently and frequently, and it is not uncommon to seek ways to ensure that identity information is not cloned or used fraudulently. Some solutions, such as EMV smart cards, use embedded chips instead of traditional magnetic stripes to store identity data. However, with this method based on mathematical methods, the information in the storage card can still be ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a new type of anti-peeping light-emitting warning optical PUF, which effectively utilizes the light-emitting behavior of long-lasting luminescent materials under illumination, and can be used as an effective basis for judging whether the PUF has been spied on, and solves the problem that ordinary optical PUFs cannot To prevent the attacker from using the incentive light to spy on the defect of the PUF excitation-response pair, and then use the long afterglow effect produced by the long afterglow material under ambient light to realize the function of anti-snooping luminous warning. The optical PUF has high security performance
