The invention relates to a method for securely providing a personalized electronic identity on a terminal (2) which can be used by a user (1) for identification purposes when claiming an online service. In the method, an identification application is ran on a terminal (2), which is assigned to a user (1), in a system comprising data processing devices (9; 10; 11; 12) and said terminal (2), and additionally a personalization application and an identity provider application are ran. The method has the following steps in particular; transmitting a request to transmit an identity attribute assigned to the user (1) front the personalization application to the identity provider application; transmitting the identity attribute from the identity provider application to the personalization application after an agreement to transmit the identity attribute by means of the identity provider application is received from the user (1); generating an asymmetric key pair with a public and a private key on the terminal (2) by means of the identification application; transmitting the public-key from tire identification application on the terminal (2) to the personalization application; and generating an electronic certificate for the public-key by means of tire personalization application and storing the electronic certificate in a data storage device in order to form a first public-key infrastructure of the personalization application, additionally having the steps of: generating a hash value for the identity attribute and recording the hash value onto the electronic certificate. The identity attribute is encoded and transmitted together with the electronic certificate from the personalization application to the identification application (14) on the terminal (2), where both are stored in a local storage device of the terminal (2).

The present invention relates to a method for distributing digital keys. The method includes the steps of a first database storing a plurality of keys relating to a plurality of products; for each product, transferring keys from the first database to a corresponding cache in a second database; in response to a request for a key for a product, retrieving and distributing a key from the corresponding cache; and refreshing the corresponding cache by transferring further keys from the first database to the corresponding cache. A system for distributing digital keys is also disclosed.

A method of remotely initializing at least one device is disclosed. The method includes initializing at a local host a cryptographic authorization sequence after receiving a secure input value. The method further includes receiving at a local host cryptographic controller a first authorization request from a first remote device. After a challenge-response authentication protocol, the first remote device is authenticated and receives a public key infrastructure certificate. The method includes receiving at a first remote cryptographic controller a second request from a second remote device. After a challenge-response authentication protocol, the first remote device is authenticated, but does not receive a public key infrastructure certificate. A system for remotely initiating at least one device is also disclosed.

Methods, systems, and computer programs are presented for protecting restricted actions on encryption keys that control the management of data stored by a service provider. In some implementations, a of the service provider receives a request to generate a data encryption policy (DEP) for data stored by the of the service provider for a customer, the request including a reference to a customer key and an availability key. The customer key and the availability key are root keys for encrypting a data encryption key. The data encryption key is used to encrypt the data stored by the service provider for the customer. Further, destructive changes to the availability key require receiving an approval from an account of the service provider. The of the service provider validates the DEP. The of the service provider stores the DEP based on the validation.

A balance and control system may write a data file transfer confirmation from a transmitter system to a blockchain in response to the transmitter system transmitting a data file to a receiver system with the confirmation including a transmitter system address, a receiver system address, and a first hash of the data file. The system may also write a data file transfer acknowledgement from a receiver system to the blockchain with the acknowledgement including the transmitter system address, the receiver system address, and a second hash of the data file. The blockchain may execute a smart contract to compare the first hash of the data file to the second hash of the data file to identify an out-of-balance file transfer event. A monitoring device of the B&C system may read the out-of-balance file transfer event from the blockchain.

A method authenticates nodes in a communication network of an automation installation. Respective authentication information is transmitted to an authentication server, which takes the authentication information as a basis for admitting or rejecting the nodes in the communication network as subscribers. In order to be able to perform an authentication of a node even in a communication network configured with redundancy, the communication network contains multiple nodes, each of which has at least two communication ports. The communication network executes a spanning tree protocol and at least two of the nodes use their mutually facing communication ports to interchange authentication requests and send the respective received authentication information to an authentication server, connected to the communication network, that uses the respective received authentication information to perform a check on the authenticity of the node and admits or rejects the node in the communication network based on the check.

A method for a device comprises enrolling a specified application installed on the device into a chain of trust provided by a private key infrastructure. In the chain of trust, a child certificate is attested as valid by an attestor associated with a parent certificate in the chain of trust. Enrolling includes generating an application certificate 20-A for verifying that the specified application is installed on the device 2. The application certificate is a descendant certificate of the device certificate associated with the device and the chain of trust.

Methods, systems, and computer programs are presented for protecting restricted actions on encryption keys that control the management of data stored by a service provider. In some implementations, a system of the service provider receives a request to generate a data encryption policy (DEP) for data stored by the system of the service provider for a customer, the request including a reference to a customer key and an availability key. The customer key and the availability key are root keys for encrypting a data encryption key. The data encryption key is used to encrypt the data stored by the service provider for the customer. Further, destructive changes to the availability key require receiving an approval from an account of the service provider. The system of the service provider validates the DEP. The system of the service provider stores the DEP based on the validation.

A system and method for authentication of a secure element cooperating with a Mobile Equipment forming a terminal in a telecommunication network is provided. The telecommunication network comprises a SEAF and a AUSF/UDM/ARPF. The method includes generating an anchor key (K.sub.SEAF_SRT) for the communication between the terminal and the SEAF according to 3GPP TS 33.501, wherein the anchor key (K.sub.SEAF_SRT) is indirectly derived from a key (K.sub.SRT) obtained by deriving from the long-term key K and a secure registration token SRT sent by the terminal to the AUSF/UDM/ARPF and concealed with the AUSF/UDM/ARPF public key along with its SUPI in the SUCI. Other embodiments are disclosed.
