Patent ID: 10939279

Abstract:
The present disclosure relates to a communication technique for combining a 5G communication system for supporting a higher data transmission rate than a 4G system with an IoT technology, and a system therefor. The present disclosure can be applied to 5G communication and IoT related technology-based intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety related services, etc.). The present invention performs cross-certification of a universal integrated circuit card (UICC) with a subscription manager data preparation+ (SM-DP+) system in a wireless communication system, and receives a profile from the SM-DP+ system according to the cross-certification result, wherein the profile comprises one of a profile encrypted on the basis of a key set established according to the cross-certification result, and a profile transmitted through a session established according to the cross-certification result.
