  • Patent number: 11516191
    Abstract: A method of secure data export from an automotive ECU to a requesting entity includes receiving a signed request, the request transmitting a first public encryption key. The signature is verified using a second public key stored in the automotive ECU. Further, the requesting entity is authenticated. Only upon successful verification and authentication the automotive ECU generates a random symmetric key for encrypting the data to be exported. The symmetric key is encrypted using the first public key received in the request, and unencrypted data is deleted. The encrypted data is exported to the requesting entity, which decrypts the symmetric key using a first private key associated with the first public key, and decrypts the data encrypted with the symmetric key.

  • Patent number: 11509480
    Abstract: A method of attestation of a host machine based on runtime configuration of the host machine is provided. The method receives, at an attestation machine, a request from the host machine for attestation of a software executing on the host machine, the request including at least one security-related configuration of the software at launch time and a corresponding runtime behavior of the software when the security-related configuration changes. The method then generates a claim based on evaluating a value associated with the at least one security-related configuration and the corresponding runtime behavior of the software when the value changes. The method also generates an attestation token after a successful attestation of the software and include in the attestation token the generated claim. The method further transmits the attestation token to the host machine.

  • Patent number: 11509694
    Abstract: Disclosed herein are embodiments of systems and methods that dynamically reconfigure a multi-tiered system of network devices and software applications in response to an ongoing and/or anticipated cyber-attack. The dynamic reconfiguration of the network devices may consist of a wide range of processes, which may include generating new network addresses for individual network devices; reconfiguring the network devices by creating firewalls, changing protocols between the network devices in a multi-tier reconfiguration solution, changing the cloud infrastructure provider of the network devices, even when the underlying network infrastructure ecosystem differs across cloud service providers (CSPs); and maintaining a secure and updated data model of a record of reconfigured network devices and their dependencies to allow legitimate users of the network devices to understand reconfiguration actions that are hidden from malicious users such as hackers and cyber-attackers.

  • Patent number: 11503465
    Abstract: A novel and useful mechanism for providing security features to a wireless communications system that otherwise does not have such features. Security features including encryption and decryption of communications, secure key exchange, secure pairing, and secure re-pairing are provided. The invention is applicable to wireless communication systems such as IO-Link Wireless. The encryption/decryption mechanism uses AES-256 block cypher with counter mode to generate blocks of cypher bits used to encrypt and decrypt communications between the master and devices. Session keys are generated using a random salt and a counter value. The random salt is generated using a secure random number generator such as the CSPRNG algorithm. A master key (or device key) is also used in generating session keys. Session keys are not permanent and are used to encrypt/decrypt only a finite amount of data. Once exhausted, the session key is replaced by a new one and cypher bits are generated using the new session key.

  • Patent number: 11503064
    Abstract: Disclosed herein are embodiments of systems, methods, and products comprise an analytic server, which provides a SilverlineRT system that prioritizes and analyzes security alerts and events. The server builds an attack tree based on attack detection rules. The server monitors large-scale distributed systems and receives alerts from various devices. The server determines attacks using the attack tree while excluding false alarms. The server determines impact and risk metrics for attacks in real-time, and calculates an impact score for each attack. The server ranks and prioritizes the attacks based on the impact scores. The server also generates real-time reports. By consider the mission and system specific context in the analysis alert information, the server gives insight into the overall context of problems and potential solutions, improving decision-making. By showing the impacts of alters, the server allows security personnel to prioritize responses and focus on highest value defense activities.

  • Patent number: 11481511
    Abstract: A system for storing and managing secure information is disclosed that includes a secure identity and profiling system, which serves as a middleman between a user and an entity requesting personally identifiable information (PII) from the user. The system collects the PII from the user and stores it securely, such as in an alternate blockchain in an encrypted form. The location of the that PII within the alternate blockchain may be indexed using smart contracts in a main blockchain that can only be read with an access token generated and supplied by the user's mobile device. When an entity requests PII from the user that has already been collected and securely stored, the user can provide permission to release that PII by providing the access token. The system will use the access token to locate where the PII is stored and release the PII to the requesting entity.

  • Patent number: 11463471
    Abstract: The disclosure relates to methods for establishing a secure communication link between a mobile station and a secondary base station in a mobile communication system. The disclosure is also providing mobile communication system for performing these methods, and computer readable media the instructions of which cause the mobile communication system to perform the methods described herein. Specifically, the disclosure suggests that in response to the detected or signaled potential security breach, the master base station increments a freshness counter for re-initializing the communication between the mobile station and the secondary base station; and the mobile station and the secondary base station re-initialize the communication there between. The re-initialization is performed under the control of the master base station and further includes deriving a same security key based on said incremented freshness counter, and establishing the secure communication link utilizing the same, derived security key.

  • Patent number: 11445337
    Abstract: A method of communicating between a terminal device and a back-end system assigned to the terminal device, the terminal device receives via a direct wireless communication link an authorization code from the mobile communication device. Responsive to receiving the authorization code, the terminal device transmits via the direct wireless communication link to the mobile communication device a terminal report message which includes a message content part and a message addressing part. The mobile communication device transmits the terminal report message in a forwarding message via a telecommunications network to a remote message processing system determined by the addressing part. The remote message processing system determines from the addressing part the back-end system assigned to the electronic terminal device and transfers the content part of the terminal report message to the back-end system.
