    摘要： The present disclosure relates to a security circuit for detecting physical attacks on a system semiconductor. The security circuit includes at least: a shielding layer having a mesh structure composed of a transmission line; a processor configured to determine that a focused ion beam (FIB) circuit editing attack was detected when a difference between predetermined counter output and a first counter output is less than a first reference value; determine that a microprobing attack was detected when a difference between the second counter output and the first counter output exceeds a second reference value; and output an alarm signal when detecting the circuit editing attack or the microprobing attack.

    摘要： The present disclosure discloses a device binding method and device, used to resolve the issue of the prior art in which the operation of controlling a smart device in a certain position is cumbersome. The method of embodiments of the present disclosure comprises: a user terminal sending target address information to a server, the server encrypting the target address information, generating a verification password, and sending the verification password to the user terminal; the user terminal sending, by means of a transmission device, the verification password to a device to be bound; the device sending the received verification password and a device identifier of the device to the server; and if the verification password sent by the device is the same as the verification password generated by the server, the server binding the target address information corresponding to the received verification password to the device identifier.

    摘要： Training an adversarial perturbation detector comprises accessing a training set comprising an enrolled biometric sample xi and a public biometric sample x of an enrolled user, and submitted biometric samples x′ of a second user, the submitted biometric samples x′ comprising perturbed adversarial samples x′+Δx′. A transformation function k(⋅) is provided having learnable a parameter θ and a classifier having a learnable parameter σ. The training set is used to learn the parameters θ and σ by inputting the training set to the transformation function k(⋅). The transformation function k(⋅) generates transformed enrolled samples k(xi), a transformed public biometric sample k(x), and a transformed adversarial sample k(x′+Δx′). The classifier classifies the transformed adversarial sample k(x′+Δx′) as a success or as a fail based on the transformed enrolled samples k(xi). Based on a result of the classification, the learnable parameters θ and σ are updated.

    摘要： The invention relates to a method for setting up a communication connection to a server for a requesting network device. The method comprises: receiving reference authentication data; storing the reference authentication data; comparing received the authentication data of the requesting network device to the reference authentication data; requesting a communication connection from the server; and generating an acknowledgement signal to the requesting network device, the acknowledgement signal indicating the requesting network device an acceptance to connect to the server and a network address to be used for the connection, receiving a connection request from the network device; and combining the connection request with the communication connection set up between the authentication server and the server. The invention also relates to an authentication server device, a communication system, and a computer program product.

    摘要： Method for authenticating at least one ventilator with at least one remote station, wherein the ventilator can connect itself via at least one interface to the remote station, at least one authentication file is stored on the ventilator, the authentication file contains at least one signature code of a signing authority, and a public keycode of the signing authority is known to the remote station, the ventilator sends the authentication file to the remote station when establishing the connection to the remote station, the remote station checks the signature code of the authentication file using the public keycode as to whether the signature code originates from the signing point and the ventilator is authenticated when the remote station recognizes the signature code as originating from the signing authority.

    摘要： The disclosed computer-implemented method for dynamic formjacking protection may include identifying a sensitive data input field element on a webform loaded in a browser, creating a secure isolated container overlaid on the identified sensitive data input field element, and collecting, via the secure isolated container, real input data intended for the sensitive data input field element. The method may also include inserting dummy data into the sensitive data input field element and intercepting a form submit request from the webform to a destination. The method may further include determining whether the destination is a trusted destination, and when the destination is determined to be the trusted destination, modifying the form submit request to allow the real input data to be sent to the trusted destination. The method may also include sending the form submit request to the destination. Various other methods, systems, and computer-readable media are also disclosed.
