An electronic device according to various embodiments of the present disclosure can comprise: a front plate facing a first direction; a rear plate facing a second direction, which is opposite to the first direction; at least one antenna module arranged between the front plate and the rear plate; and at least one heat dissipation sheet spaced from the at least one antenna module so as to be arranged to come in contact with the rear plate. The at least one heat dissipation sheet can comprise a ceramic filler and a binder resin mixed with the ceramic filler.

Heat dissipation sheet and electronic device including same

The present invention Includes using an embedded SIM (eSIM) associated with a newly-opened mobile network operator (MNO) system and a receiving MNO system, the method performs the steps of: generating a security domain (SD) for a receiving MNO on the basis of a request from the newly-opened MNO system; injecting a prior SD key value; installing a secure applet for key generation and secure arithmetic operations, injecting a new SD key value on the basis of a request from the receiving MNO, and transmitting only a public key to the receiving MNO system after generating key pairs for the receiving MNO; and decoding a receiving MNO profile with a private key corresponding to the public key after receiving the receiving MNO profile from the receiving MNO system or the newly-opened MNO system.

Method for changing MNO in embedded SIM on basis of dynamic key generation and embedded SIM and recording medium therefor

The present invention provides a method and an apparatus for managing (mutual authorization with a SIM, secure communication, channel formation, application and data issuance, etc.) an embedded SIM (eSIM or eUICC) by generating and extraditing a security domain using GlobalPlatform technology in which authorized management privilege and delegated management privilege functions are implemented.

Method for changing MNO in embedded SIM on basis of special privilege, and embedded SIM and recording medium therefore

The present invention relates to profile access credentials used for encoding profiles in a system comprising an mobile network operator (MNO), a subscription manager (SM), an embedded UICC (eUICC) and the like, that is, a method for storing/managing an eUICC publication key and a corresponding secret or the like inside the eUICC. In addition, the invention also provides a method for transmitting information on profile access credentials inside the eUICC to external entities for encoding and the like.

Method for managing embedded UICC and embedded UICC, MNO system, provision method, and method for changing MNO using same

The present invention relates to a system constituted by a mobile network operator (MNO), a subscription manager (SM), and an embedded UICC (eUICC), wherein the MNO system or the SM stores an eUICC certificate that can verify the identity of the eUICC, transfers the eUICC certificate to the MNO system or the SM in a provisioning or MNO changing process, verifies the identity of a corresponding eUICC using the received eUICC certificate, and encrypts and transfers a profile to the eUICC only if the verification is successful so that the eUICC may be verified during the provisioning or MNO changing processes.

Certification method using an embedded UICC certificate, provisioning and MNO changing methods using the certification method, embedded UICC therefor, MNO system, and recording medium

The present invention provides a method wherein an MNO receives a secret key allocated to a corresponding embedded UICC (eUICC) through SM-SR (secure routing) in an environment where SM is divided and implemented as SM-SR and SM-DP (data preparation), that is, provided is a method wherein the MNO dynamically acquires the secret key (public key or the like) from the corresponding eUICC through the SM-SR and uses the acquired secret key. In addition, the present invention allows the eUICC to receive an encrypted profile from the MNO or the SM and decrypts the encrypted profile using profile access credential information (a secret key corresponding to an eUICC public key) stored in the eUICC to use the decrypted profile, thereby securely transmitting important data such as operation profiles, and blocking external entities such as a device or terminal from accessing the important data.
