  • Patent number: 11916924
    Abstract: Aspects of the present disclosure address systems, methods, and devices for enabling secure communication between electronic control units (ECUs) in a vehicle. The system may include a first and second ECU from a plurality of ECUs in the vehicle. The first ECU is to enable secure communication between the plurality of ECUs by performing operations that include provisioning the second ECU with authentication data for authenticating messages exchanged with a third ECU and provisioning the third ECU with a set of security keys to enable the third ECU to securely exchange messages with the second ECU. The second ECU receives, from the third ECU, a secure message that is cryptographically signed using a security key from the set of security keys provisioned to the third ECU, and the second ECU authenticates the secure message by comparing the authentication data with an authentication signal.

  • Patent number: 11876914
    Abstract: Systems and methods for securely exchanging cryptographically signed records are disclosed. In one aspect, after receiving a content request, a sender device can send a record to a receiver device (e.g., an agent device) making the request. The record can be sent via a short range link in a decentralized (e.g., peer-to-peer) manner while the devices may not be in communication with a centralized processing platform. The record can comprise a sender signature created using the sender device's private key. The receiver device can verify the authenticity of the sender signature using the sender device's public key. After adding a cryptography-based receiver signature, the receiver device can redeem the record with the platform. Upon successful verification of the record, the platform can perform as instructed by a content of the record (e.g., modifying or updating a user account).

  • Patent number: 11641285
    Abstract: Certificates issued by a CA are distributed across multiple CRLs. Each certificate issued by the CA is assigned to a specific CRL, and the address of that CRL is written to the appropriate field of the certificate, such that an authenticating application can subsequently determine if the certificate is revoked. When the CA revokes a specific one of the issued certificates, it determines to which CRL the revoked certificate is assigned, and updates the specific CRL accordingly. In some embodiments, a single one of the multiple CRLs is active for assignment of certificates at any given time, and each certificate issued by the CA is assigned to the currently active CRL. In other embodiments, assignments of issued certificates are distributed between different ones of a pre-determined number of multiple CRLs by applying a statistical distribution formula to each issued certificate to determine a corresponding target CRL.

Web clients communicate with the proxy revocation service through use of API message to perform revocation checks, rather than communicating with the public certificate authorities using an online certificate status protocol (OCSP). Use of the proxy revocation service provides both a reliable service for performing revocation checks as well as shifts the complexity away from the web clients.

In accordance with certain techniques, a first sub-process of a snapshot deletion process on a first data block of the snapshot data is performed with a first thread. The snapshot deletion process includes at least the first sub-process and a second sub-process, the first and second sub-processes being performed sequentially. In response to an end of the first sub-process performed with the first thread, the second sub-process on the first data block is performed with the first thread. In parallel with performing, with the first thread, the second sub-process on the first data block, the first sub-process on a second data block of the snapshot data is performed with a second thread different from the first thread, the second data block being different from the first data block. Such techniques improve IO lock contention, system resource utilization rate and parallelism, response time and system overhead.

  • Patent number: 11256540
    Abstract: For each server under consideration for container migration, whether the server has a value for a first parameter that precludes the server from being migrated to a container is determined. Each server having a value that precludes the serve from being migrated to a container is removed from further consideration. For each server remaining under consideration, a value of the server for each second parameter of a number of second parameters is determined, and the values of the server for the second parameters are weighted to yield a weight for the server. The servers remaining under consideration for migration are ranked based at least on the weights for the servers, yielding an order in which the servers are to migrated.

  • Patent number: 11237534
    Abstract: A method of providing a plurality of controller certificates for a plurality of controllers within a Building Management System (BMS) includes downloading project information defining the BMS and using the downloaded project information to solicit a Certificate Signing Request (CSR) from each of the plurality of controllers of the BMS. The received CSRs are uploaded to a remote server so that the remote server can generate a corresponding controller certificate for each of the plurality of controllers of the BMS. The generated controller certificates are then downloaded to the corresponding one of the plurality of controllers of the BMS.

  • Patent number: 11212274
    Abstract: Techniques are disclosed for accelerating online certificate status protocol (OCSP) response distribution to relying parties using a content delivery network (CDN). A certificate authority generates updated OCSP responses for OCSP responses cached in the CDN that are about to expire. In addition, the certificate authority pre-generates cache keys in place of CDNs generating the keys. The certificate authority sends the OCSP responses and the cache keys in one transaction, and the CDN, in turn, consumes the new OCSP responses using the cache keys.

  • Patent number: 11158309
    Abstract: Techniques are described for automatically distributing validated user safety alerts from a networked computing device. The networked computing device may be configured to operate as an autonomous agent to perform actions on behalf of a user without receiving direct instructions from the user. For example, the autonomous agent computing device may be configured to make certain purchases, send alerts or reminders, or perform other functions in accordance with preprogrammed rules. According to the disclosed techniques, the autonomous agent computing device is configured to automatically generate and send an alert to one or more computing devices associated with the user upon detecting a safety concern for the user. The autonomous agent also uses a signing key associated with its digital certificate, which verifies the identity of the autonomous agent, to sign the alert such that a third-party server may validate the alert prior to distribution to the destination computing devices.
