摘要

Embodiments of the present invention are for use in increasing the security in writing an ESIM number and prevent risks of the ESIM number being maliciously hijacked or tampered. Disclosed is an ESIM number writing method. The method of the embodiments of the present invention comprises: a security system receives an ESIM number writing instruction; if the security system finds the ESIM number writing instruction to match an ESIM number server whitelist, then the security system transmits an ESIM number write request to a corresponding ESIM number server via a virtual private network (VPN) on the basis of the ESIM number writing instruction; the security system receives encrypted ESIM number data transmitted by the ESIM number server on the basis of the ESIM number write request; the security system decrypts the encrypted ESIM number data; and the security system writes the decrypted ESIM number data into an ESIM device. Also provided in the embodiments of the present invention are the security system and the ESIM number server that effectively circumvent potential risks that may be found in ESIM number writing steps, thus increasing the security of the ESIM number.
