Systems and methods are described for increasing web browser security on a user device managed by a device management system. In an example, the user device can use an unmanaged web browser to access secure enterprise content using a browser extension provided by the enterprise. When a user attempts to access secure content from an unmanaged browser, the device management system can communicate with the extension and a management application on the user device to authenticate the user and verify that the user device complies with certain policies. In one example, the device management system can include an extension recommendation engine that analyzes user browsing data and recommends browser extensions for the user. Based on policies, the device management system can recommend the extension to the user or force installation of the extension on the user device.

A method of adding a first publisher to a security group includes receiving a key request for keys for the first publisher, wherein the key request has at least one credential associated with the first publisher and a key parameter index indicative of a bandwidth of the first publisher, includes modifying a lifetime value of the at least one key of the security group based on the key parameter index of the received key request, wherein an expiry of the at least one key is based on the lifetime value of the one or more keys; and includes transmitting the at least one key and the modified lifetime value of the at least one key to the first publisher, where the first publisher is configured to publish at least one message encrypted using the at least one key, prior to expiry of the at least one key.

The present disclosure relates to systems, non-transitory computer-readable media, and methods for implementing asymmetric cryptography for digital rights licensing during system disruptions. In particular embodiments, the disclosed systems transmit, to a licensing device that issues digital licenses, a digital communication indicating a system outage of an identity server that verifies digital licenses of client devices. Based on the digital communication, the disclosed systems call a monitoring device using a licensing device identifier. In response to the call, one or more embodiments of the disclosed systems use the monitoring device to encrypt and transmit a verification token back to the licensing device. In certain implementations, the disclosed systems then verify the system outage by decrypting the encrypted verification token and validating a corresponding digital signature. Upon validation, the disclosed systems can trigger a failover mechanism for issuing a grace digital license to one or more client devices during the system outage.

Embodiments of the present invention provide a system for facilitating a secure way to allow primary users and secondary users to perform interactions remotely via an automated machine, such as an automated teller machine (ATM). In particular, the system may assign exclusive control over an automated device to a primary user via a computing device connected to the same local network or virtual private network as the automated machine, and may allow the primary user to communicate via the automated machine with a secondary user who wishes to complete one or more resource interactions. In some embodiments, the system may invoke one or more auxiliary devices on the same network to complete the interaction.

A tracking device can use a permanent encryption key pair to encrypt a temporary private key that corresponds to a set of diversified temporary public keys. When a community mobile device subsequently detects the tracking device, the central tracking system provides a diversified temporary public key to the community mobile device. The community mobile device uses the diversified temporary public key to encrypt location data representative of a location of the community mobile device, and provides the encrypted location data to the central tracking system. When a user subsequently requests a location of the tracking device from the central tracking system, the central tracking system provides the encrypted temporary private key and the encrypted location data to a device of the user, and the device can decrypt the encrypted temporary private key using the permanent encryption key pair, and decrypt the encrypted location data using the decrypted temporary private key.

A security authentication system for a website provides a safe login without having to directly enter an ID and a password on a user device requesting login to the website. A first user device receives one-time use authentication information from a second user device after the second user device received the one-time use authentication information from an authentication server without the authentication server receiving user login authentication information from the second user device. A request is transmitted to the authentication server based on the one-time use authentication information and the user login authentication information. In response to the request, one-time password (OTP) information is received from the authentication server. The OTP information is presented by the first user device, such that the OTP information can be entered into the second user device and used in a request to log in to the website.

An authorization method and an authorization system are provided. The authorization method includes displaying, by a service device, authorization information on an e-paper arranged on the service device; obtaining, by a user device, the authorization information from the e-paper; and using, by the user device, the authorization information displayed on the e-paper to perform an authorization operation between the user device and the service device.

Provided is a method of an electronic device for performing ultra wide band (UWB) communication. The method includes receiving upper bit information including pre-set at least one parameter via a UWB command interface (UCI), obtaining slot count information and key information including a constant key value, and performing static scrambled timestamp sequence (STS) generation, based on the upper bit information, the slot count information, and the key information.

The described techniques facilitate the secure transmission of sensor measurement data to an ECU by implementing an authentication procedure. The authentication procedure includes an integrated circuit (IC) generating authentication tags by encrypting portions of sensor measurement data. These authentication tags are then transmitted together with the sensor measurement data as authenticated sensor measurement data. The ECU may then use the authentication tags to authenticate the sensor measurement data based upon a comparison of the portions of the sensor measurement data sensor measurement data to the authentication tag that is expected to be generated for those portions of sensor measurement data.

A physical access control system enables acceptable portal entry codes upon receiving each physical access request by operating on the elapsed time from a previous physical access request to generate a temporal credential. The controller receives a plurality of physical access requests from a plurality of mobile application devices. Upon authenticating the first access request, the controller eliminates repetition from the space of acceptable successor requests from each mobile application device. Monotonic nonces advance the range of temporal code matches. Entry code generation is decentralized to distributed application devices and is inherently unknowable until a successor access request is initiated by the same application device.
