  • 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: 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.

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).

    Abstract: Embodiments provided herein identify a certificate issuer (CI) to be relied on as a trusted third party by an electronic subscriber identity module (eSIM) server in remote SIM provisioning (RSP) transactions with an embedded universal integrated circuit card (eUICC). In an RSP ecosystem, multiple CIs may exist. Parties rely on public key infrastructure (PKI) techniques for establishment of trust. Trust may be established based on a trusted third party such as a CI. Parties need to agree on the CI in order for some PKI techniques to be useful. Embodiments provided herein describe approaches for an eUICC and an eSIM server to arrive at an agreed-on CI. Candidate or negotiated CIs may be indicated on a public key identifier (PKID) list.

  • Patent number: 10887294
    Abstract: A set of cryptographic keys are synchronized across a set of HSMs that are configured in an HSM cluster. The set of cryptographic keys is maintained in a synchronized state by HSM cluster clients running on client computer systems with corresponding client applications. If the HSM cluster becomes unsynchronized, an HSM cluster client attempts to lock the HSM cluster and reestablish synchronization of the cryptographic keys across the HSM cluster. HSMs within the HSM cluster are able to establish an encrypted communication channel to other HSMs without revealing the contents of their communications to their respective host computer systems. Individual HSMs in the HSM cluster may include features that assist the HSM cluster client in determining whether each HSM is up-to-date, identifying particular keys that are not up-to-date, and copying keys from one HSM to another HSM within the HSM cluster.

  • Patent number: 10848301
    Abstract: One embodiment of the present application sets forth a computer-implemented method for establishing trust for handles used to identify digital objects in a digital object architecture (DOA) by associating a first attester identifier with a first attester from a trusted public key infrastructure (PKI), identifying a first digital object public key for a first digital object, generating, by the first attester, a first digital object identity attestation that associates the first digital object public key with a handle identifier for the first digital object, wherein the handle identifier is external to the trusted PKI, and generating a first attester identity attestation attesting that the first attester is authentic, where the first attester identity attestation includes the first attester identifier.

  • Patent number: 10609082
    Abstract: Methods for composable user journeys for user authentication via an identity experience framework are performed by systems and apparatuses. Initiating a user authentication process for an application triggers application calls for dynamic invocation of a specific identity policy, required by the application, of a number of identity policies managed by a host of the identity experience framework. User interfaces defined by the identity policies are provided from the host to the application for interaction by the user and entry of identity information needed to authenticate the user according to specified verification providers. Identity claims and token requests are provided from the application to the host which then authenticates the identity claims via the verification providers and mints a token that includes the claims required by the application, according to the identity policy. The application consumes the token to complete the token request and allow the user access to the application.
