Abstract

Embodiments of the present invention provide a profile processing method, device, and system. The profile processing method of the present invention includes: acquiring tag information, the tag information including tag data; sending a profile download request to the subscription management device, the profile download request at least including the tag data; receiving the tag data sent by the subscription management device A first profile, where the first profile is generated by the subscription management device according to one selected from at least one second profile associated with the tag data. The embodiment of the present invention associates one tagged data with multiple profiles and performs security protection on the tagged data, which not only realizes the reuse of tagged data, reduces costs, but also prevents replay attacks and improves security.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a profile processing method, device and system. Background technique [0002] The existing Subscriber Identity Module (SIM for short) card or Universal Integrated Circuit Card (UICC for short) card is generally centralized by a Mobile Network Operator (MNO) to Card dealer order, so before leaving the factory, the contract information required to access the mobile operator network, including the International Mobile Subscriber Identification Number (International Mobile Subscriber Identification Number, referred to as: IMSI) necessary to access the mobile operator network, Ki, encryption algorithm parameters, etc. are downloaded to the card, and the user purchases a SIM card or UICC card and inserts it into the terminal to access the network. As for an embedded universal integrated circuit card (embedded UICC, eUICC for short), it may not necessarily be purc...
