  • Publication number: 20240073030
    Abstract: Systems and methods for authenticating public key infrastructure certificate enrollment using certificate entitlement licenses. One example system includes a device manager including an electronic processor. The electronic processor is configured to receive a request for software for an electronic device including a unique electronic device identifier. The electronic processor is configured to determine, based on the request, whether the electronic device is entitled to participate in a certificate management service. The electronic processor is configured to, responsive to determining that the electronic device is entitled to participate in a certificate management service, transmit a certificate entitlement license request including the unique device identifier to a certificate entitlement license manager. The electronic processor is configured to receive, from the certificate entitlement license manager, a certificate entitlement license for the unique device identifier.

  • Patent number: 11502849
    Abstract: A mobile device and method are provided that allow for registering the mobile device using a machine readable optical label. The mobile device receives a machine readable optical label, such as a QR code or a bar code. The machine readable optical label includes authentication data and security information. The mobile device scans machine readable optical label to read the authentication data and the security information. The mobile device validates the machine readable optical label and generates certificate request, the certificate request digitally signed using the authentication data and the security information. The mobile device transmits the certificate signing request to a registration authority.

  • Patent number: 11139989
    Abstract: A method, mobile device, and PKI are provided for enrolling a mobile device into a PKI domain for certificate management is provided. A first asymmetric key pair and a unique identifier is established in a device. The first asymmetric key pair includes a public key and a private key. The public key and the unique identifier are transferred to the PKI domain. The public key and the unique identifier are imported into the PKI domain. The device generates a second asymmetric kay pair and sends a certificate signing request (CSR) that is protected with the digital signature of the first asymmetric key pair. The CSR is transferred to the PKI domain. The PKI domain authenticates the CSR using the first public key and the unique identifier. Upon validation, the PKI domain issues a certificate to the device.

  • Publication number: 20160142215
    Abstract: A certificate management processor (CMP) in a public key infrastructure (PKI) receives a request for a certificate management operation. The CMP determines that the request is associated with at least one of an end entity and a service. The CMP identifies a certificate management identifier associated with at least one of the end entity and the service. The CMP retrieves at least one status associated with the certificate management identifier and/or at least one status associated with the certificate management operation. The CMP performs the certificate management operation on a certificate when the retrieved at least one status is determined to not be suspended.

  • Publication number: 20160142216
    Abstract: A Public Key Infrastructure (PM) device receives a certificate signing request (CSR) from an end entity. The PKI device obtains at least one of: a controlling attribute of at least one PKI device associated with processing of the certificate signing request and a controlling attribute associated with the CSR. The PKI device obtains an end entity policy object (EEPO) to be associated with the end entity based on at least one obtained controlling attribute. Based on the obtained EEPO, the PKI device determines at least one attribute and at least one value associated with the attribute this is to be included in a certificate and issues, to the end entity, the certificate including the at least one attribute.

  • Patent number: 6804518
    Abstract: In a network supporting concurrent services, mobile terminated call delivery processing is simplified by an apparatus and method for forcing a Mobile Station (MS) (118) to register with a new Mobile Switching Center (MSC) (110) after a hard handoff has occurred. The mobile station registers with the new MSC when the mobile station is in an active data call, but not in an active voice call. The method momentarily sends the data session to dormant mode while the mobile station performs location updating. The method utilizes a new information element in a Clear Command message that allows the MSC to indicate to the Base Station Controller (112) that the period a data session must remain dormant should be very brief. This brief period of time limits the impact on the MS user.
