Abstract
A module with an embedded universal integrated circuit card (eUICC) can include a first eUICC profile and a set of cryptographic algorithms. The first eUICC profile can include an initial shared secret network key K for authentication with a wireless network. The module can receive a key K network token from, and send a key K module token to, an eUICC subscription manager (eUICC-SM). The module can use the key K network token, a derived module private key, a key derivation function, and a shared secret algorithm to derive a shared secret key that supports communication with the UICC-SM. eUICC-SM can use the received key K module token, a private key, the key derivation function, and the shared secret algorithm in order to derive the same shared secret key derived by the module. The module can subsequently receive a second eUICC profile encrypted using the derived shared secret key.
