A smart card registry management method, device and storage medium

Abstract

The invention relates to the technical field of smart cards, and discloses a registry management method, a device and a storage medium for a smart card. The smart card registry management method includes: constructing a smart card registry frame, the frame comprising a first area and several second areas; receiving Create a profile instruction, according to the instruction, create a second registry corresponding to the profile in one of the second areas, the second registry includes the second application registry, the second Cap package registry and the second profile information; wherein, the second registry Areas correspond to profiles one-to-one and the number is equal. The present invention has at least the following beneficial effects: the access efficiency of the eUICC card under the characteristics of supporting multiple profiles and multiple operators and requiring data to be independent and invisible to each other can be improved.

Description

technical field [0001] The present invention relates to the technical field of smart cards, in particular to a registry management method, device and storage medium for smart cards. Background technique [0002] With the rise of IoT applications, traditional UICC cards (Universal Integrated Circuit Cards, Universal Integrated Circuit Cards) cannot well meet some market demands. For example, terminals are deployed in places where manual card insertion or card replacement is inconvenient; or The user chooses an operator or hopes to change another operator after deploying the terminal; and the terminal using the UICC card, the UICC card is at risk of being stolen or used for other purposes; eUICC (Embedded Universal Integrated Circuit Card, embedded universal integrated circuit card) circuit card) can better meet these application scenarios. eUICC is a new UICC product form, which is embedded in the terminal device and can not be plugged or replaced like a traditional UICC; eU...

Problems solved by technology

[0003] At present, in the existing technology, when realizing the registry management of the smart card, the entire smart card uses a registry, and does not separate the registry of the profile, which makes the number of applications supported by the entire eUICC card, the number of Cap packages The number is limited, such as: use 1 byte to indicate that the maximum number of applications supported by the card can support 0xFF, and the average number of applications allocated to each profile cannot reach a sufficient number; in addition, it is necessary to identify each application or Which profile the Cap package belongs to is used to prevent access by other unrelated profile le, and the data written to the registry is operated according to the timing of downloading the application / installing the Cap package. The registry data of the same profile is most likely to be It is discontinuous, therefore, when accessing data, it is necessary to traverse the registry of the entire card, and the access efficiency is low, resulting in extremely complicated operations when downloading profile applications and deleting profiles
