Abstract: For example, within a communication network environment a possibility for retrieval of historical data indicative of events occurring within the communication network environment and obtained from one or more data sources within the communication network environment is provided. Selection criteria is specified at a first device to be applied to the historical data for a query to be performed on the historical data kept in a historical data repository associated with a second device. At least one processing instruction is specified at the first device. The processing instruction determines the generation of a report based on the defined query. The selection criteria and the processing instruction is transmitted to the second device, and the report generated at the second device based on the transmitted selection criteria and processing instruction is received.

Abstract: Embodiments of the present disclosure relate to subscription concealed identifier (SUCI) encryption. In an aspect, a terminal device generates a SUCI of the terminal device based on a subscription permanent identifier (SUPI) of the terminal device. The SUCI comprises a SUPI type indicating that both elliptic curve cryptography (ECC) and post quantum cryptography (PQC) are used in the generating of the SUCI. The terminal device further transmits the SUCI to a network device. As such, a SUCI can be defined to comprise a SUPI type indicating that both the ECC and PQC are used in the generating of the SUCI. With the SUCI generated based on both the ECC and PQC, different kinds of cryptanalytic attacks can be avoided.

Abstract: There are provided measures for data minimization in network function to network function communication. Such measures exemplarily comprise, at a first network function entity configured for communication with a second network function entity, transmitting, towards a network repository function entity, a discovery message, receiving, from said network repository function entity, a response message comprising a first encryption key of said second network function entity, encrypting data, using the first encryption key, as encrypted data, and transmitting, towards said second network function entity, a service request with said encrypted data.
