The invention relates to a method for verifying the origin of an electronic unit (1) for a control device (2) using a verification system (3), comprising the steps of: receiving a certificate signing request (7) for digitally certifying the control device (2) with the electronic unit (1) from a requesting instance using a receiving device (4) of the verification system (3), wherein the certificate signing request (7) is signed with a wrapper signature (8) of the electronic unit (1); generating a verification request (9) with a manufacturer of the electronic unit (1) based on the received wrapper signature (8) using an electronic computing device (6) of the verification system (3); transmitting the verification request (9) to the manufacturer using a sending device (5) of the verification system (3);Receiving a verification message (11) for verifying the electronic unit (1) from the manufacturer using the receiving device (4); and verifying the origin of the electronic unit (1) depending on the verification message (11) using the electronic computing device (6). The invention further relates to a computer program product and a verification system (3).

The invention relates to a method for verifying the origin of an electronic unit (1) for a control device (2) using a verification system (3), having the steps of: receiving a certificate signing request (7) for digitally certifying the control device (2) with the electronic unit (1) from a query entity by means of a receiving device (4) of the verification system (3), wherein the certificate signing request (7) is signed with a wrapper signature (8) of the electronic unit (1); generating a verification query (9) for a manufacturer of the electronic unit (1) on the basis of the received wrapper signature (8) by means of an electronic computing device (6) of the verification system (3); transmitting the verification query (9) to the manufacturer by means of a transmitting device (5) of the verification system (3); receiving a verification message (11) for verifying the electronic unit (1) from the manufacturer by means of the receiving device (4); and verifying the origin of the electronic unit (1) on the basis of the verification message (11) by means of the electronic computing device (6). The invention also relates to a computer program product and to a verification system (3).

Embodiments of the application disclose a digital certificate issuing method and related device based on a double-certificate system, a user terminal generates a first and a second public-private key pair according to an asymmetric encryption algorithm and a post-quantum key signature algorithm respectively; the first and the second public key are taken as a hybrid public key to generate a certificate signature request together with user identification information, and the certificate signature request is sent to a certificate authority terminal; the certificate authority terminal generates a hybrid key signature certificate, a hybrid key encapsulation certificate, an encrypted hybrid key encapsulation private key and an encrypted symmetric key according to the certificate signature request; the user terminal decrypts the encrypted hybrid key encapsulation private key and the symmetric key according to the first private key to obtain the hybrid key encapsulation private key; the hybrid key signature certificate and the hybrid key encapsulation certificate are installed and bound with the corresponding private key, so that the hybrid key signature certificate and the hybrid key encapsulation certificate are issued, the legal use of the certificate in a quantum algorithm resistant scenario is ensured, and the information security is improved.

A method of updating a certificate for device identification of at least one example embodiment includes generating a device identifier comprising unique information of the device, generating a device identity (ID) certificate signing request (CSR) based on the device identifier, updating the bootloader, the updating including updating a certificate of the device based on the device ID CSR using firmware of the device in response to a request of a host device, and in response to the bootloader being changed, authenticating the updating of the bootloader based on a second certificate generated by an original equipment manufacturer (OEM) of the device in response to authentication of the bootloader failing based on a first certificate generated by a manufacturer of the device.

The invention relates to a method for verifying the origin of an electronic unit (1) for a control device (2) using a verification system (3), comprising the steps of: receiving a certificate signing request (7) for digitally certifying the control device (2) with the electronic unit (1) from a requesting instance using a receiving device (4) of the verification system (3), wherein the certificate signing request (7) is signed with a wrapper signature (8) of the electronic unit (1); generating a verification request (9) with a manufacturer of the electronic unit (1) based on the received wrapper signature (8) using an electronic computing device (6) of the verification system (3); transmitting the verification request (9) to the manufacturer using a sending device (5) of the verification system (3);Receiving a verification message (11) for verifying the electronic unit (1) from the manufacturer using the receiving device (4); and verifying the origin of the electronic unit (1) depending on the verification message (11) using the electronic computing device (6). The invention further relates to a computer program product and a verification system (3).

A method of acquiring an operational certificate for an application (140) running on an authorized and / or authenticated host node (130) in a network (100), the method comprising: transmitting, by the application, a request comprising a Certificate Signing Request to a proxy engine (145) running on the authorized and / or authenticated host node; receiving, by the proxy engine, the request, and submitting the Certificate Signing Request to a Certificate Authority (155); signing, by the Certificate Authority, the operational certificate and transmitting a response comprising the signed operational certificate to the proxy engine; and forwarding, by the proxy engine, the signed operational certificate to the application.
