Registry management method and device of intelligent card and storage medium

Abstract

The invention relates to the technical field of intelligent cards, and discloses an intelligent card registry management method and device and a storage medium, and the intelligent card registry management method comprises the steps: constructing an intelligent card registry framework which comprises a first region and a plurality of second regions; a profile creating instruction is received, a second registry corresponding to the profile is created in one second region according to the instruction, and the second registry comprises a second application registry, a second Cap packet registry and second profile information; wherein the second regions are in one-to-one correspondence with the profiles, and the number of the second regions is equal to that of the profiles. The method at least has the following beneficial effects that the access efficiency of a large amount of data under the characteristics that the eUICC supports multiple profiles and multiple operators, and the data are required to be mutually independent and invisible can be improved.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a method, device and storage medium for managing a registry of smart cards. Background technique [0002] With the rise of Internet of Things applications, the traditional UICC card (Universal Integrated Circuit Card, universal integrated circuit card) cannot meet the needs of some markets. For example, the terminal is deployed in a place where it is inconvenient to manually insert or replace the card; or The user chooses the operator or hopes to change another operator after deploying the terminal; and the terminal using the UICC card, the UICC card has the 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 form of UICC product, which is embedded in the terminal equipment and cannot be plugged or replaced like...

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
