A method for key rotation includes initiating key rotation for a user account of a multi-factor authentication platform enabling one-time password authentication using a first symmetric cryptographic key; generating, at an authenticating device, a second symmetric cryptographic key; transmitting, at the authenticating device, the second symmetric cryptographic key to the multi-factor authentication platform; configuring the multi-factor authentication platform and the authenticating device to disable authentication that uses the first symmetric cryptographic key; and configuring the multi-factor authentication platform and the authenticating device to enable authentication that uses the second symmetric cryptographic key.

A key management method serves as an electronic control unit (ECU) in an onboard network system having a plurality of ECUs that perform communication by frames via a network. The method includes storing a shared key and executing encryption processing based on the shared key. The method further includes executing inspection of a security state of the shared key stored in a case where a vehicle is in at least one of the following particular states: the vehicle is not driving and is an accessory-on state; a fuel cap of the vehicle is open, and the vehicle is not driving and is fueling; the vehicle is parked, which is indicated by the gearshift; the vehicle is in a stopped state before driving, which is indicated by the gearshift; and a charging plug is connected to the vehicle, and the vehicle is electrically charging.

A key server network device may install, on the key server network device, a new decryption key based on a timer-based key rollover setting and may provide, to peer network devices, messages identifying the new decryption key. The key server network device may utilize an original encryption key, to encrypt traffic, until all of the peer network devices provide acknowledgements of installation of the new decryption key. The key server network device may be configured to utilize the original encryption key based on the timer-based key rollover setting. The key server network device may generate an alarm. The alarm may include information indicating that the key server network device is waiting for the acknowledgements from one or more peer network devices and information identifying the one or more peer network devices.

A system and method for implementing and managing a distributed data flow model is disclosed. The method includes obtaining a flow configuration file and identifying one or more socket roles and a unique identification number. The method includes establishing a TCP connection of one or more runtime nodes with the one or more flow neighbors, establishing a publisher-subscriber relationship of the one or more runtime nodes with the one or more flow neighbors, and implementing one or more bridge wires with the one or more runtime nodes and the one or more flow neighbors. Furthermore, the method includes detecting a loss of connectivity of one or more networks, determining one or more root causes of the loss of connectivity, and perform one or more operations to attain a predefined level of resiliency of the distributed data flow model.

One or more computing devices, systems, and/or methods for securely verifying devices such as protected are provided. A code may be generated for a first device. A short message service (SMS) message comprising the code may be transmitted to the first device at a mobile directory number of the first device. An entry may be created to associate the code with the mobile directory number. A determination may be made as to whether a first code within a message associated with the mobile directory number matches the code within the entry. In response to a match, the message may be processed and a status of the first device may be marked as valid, otherwise, the message may be rejected.

Systems and methods provide a transient component limited access to data in a composition. One method includes receiving a request for the transient component to access data in the composition. The composition may include permanent components operable to utilize encryption keys generated at selected intervals from a seed value shared by the permanent components. The encryption keys utilized by the permanent components at each selected interval may be identical to one another. The method also includes generating a set of encryption keys from the seed value for a specified period of time. The set of encryption keys may be identical to the encryption keys to be utilized by the permanent components at the selected intervals to occur during the specified period of time. The method further includes granting the transient component access to data in the composition for the specified period of time via the set of encryption keys.

Example implementations relate to the processing of refresh token requests at an API gateway. The API gateway determines a first time associated with receipt of the refresh token request and a second time associated with the generation of a current access token. The current access token and a refresh token in the refresh token request are provided by the API gateway to the client device for accessing a backend service. The API gateway determines whether a difference between the first time and the second time is within a pre-defined threshold duration. When the difference between the first time and the second time is within the pre-defined threshold, the API gateway denies the refresh token request for generating the new access token and transmits the current access token back to the client device.

An access management and reporting system includes a keysafe that is located outside of a building and a communication system that is located within the building. The communication system is configured to perform, over a short-range wireless communication protocol, two-way communication with a communication module of the keysafe. The system also includes a server that is located remote from the building and the keysafe. The server is configured to perform, over a long-range communication protocol, two-way communication with the communication system located within the building, is configured to manage access to the keysafe, and is configured to handle reporting related to access of the keysafe.

Methods and systems for authenticating a client device using entropy provided by a server and/or a device paired with the client device are described herein. The client device may receive a first user credential. The client device may receive first entropy from a wireless device. The client device may decrypt, using the first entropy, second entropy generated by a server. The client device may decrypt, using the second entropy, a second user credential that was stored in the client device. Based on a comparison of the first user credential with the second user credential, the client device may grant a user of the client device access to one or more resources.

A framework for managing credentials for access to a secured entity of an infrastructure service. For example, techniques for maintaining credentials for access to the secured entity within a trusted environment while utilizing the credentials for performance of actions within the infrastructure service.
