A process includes accessing a first message that is sent from an access point device. The first message includes data representing a second message that is sent by a client device. The second message is part of an exchange of messages between the client device and the access point device associated with authentication of the client device and a derivation of a first key used to encrypt and decrypt data communicated between the client device and the access point device. The second message includes a first message integrity check value. The process includes identifying, based on the second message, a pre-shared key corresponding to the client device. The identification of the pre-shared key includes determining a second message integrity check value based on a candidate pre-shared key of a plurality of candidate pre-shared keys; comparing the second message integrity check value with the first message integrity check value; and based on a result of the comparison, selecting the given candidate pre-shared key as the pre-shared key. The process includes determining a user role based on the pre-shared key. The process includes causing a third message to be sent to the access point device, where the third message includes data representing the pre-shared key and data representing the user role.

Associating pre-shared keys with client devices based on message integrity check values

The present application relates to a spectral restoring method, including: acquiring a light energy response signal matrix output by a photosensitive chip of a spectral imaging device and a standard spectrum; determining a primitive restoring function and a response signal vector of the primitive restoring function based on the light energy response signal matrix, the primitive restoring function restoring a spectral image value of a predetermined channel corresponding thereto using a predetermined pixel value of the photosensitive chip and pixel values in the vicinity thereof; acquiring a restoring tensor, the product of the restoring tensor and the response signal vector being equal to an output of the primitive restoring function based on the response signal vector; and obtaining a restored spectral image based on the product of the restoring tensor and the response signal vector. In this way, by introducing a standard spectrum and a restoring tensor to restore a spectral image, it is possible to achieve spectral restoring with high speed, easy parallel operation and high restoring accuracy.
