Embodiment Construction

[0097] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0098] With the rapid development of communication technology, security chips, especially smart card chips, have been widely used in the financial and communication fields. With the development of smart terminals and the Internet of Things, security chips represented by embedded security elements (eSE) and embedded subscriber identity modules (eSIM) have broa...

Abstract

The invention provides a storage space management method and device, a chip, equipment and a storage medium. The method comprises steps of determining to-be-processed data and target operation corresponding to the to-be-processed data, determining the data type of the to-be-processed data according to the feature information of the to-be-processed data, and carrying out the storage of the to-be-processed data based on a space management mode corresponding to the data type; calling the space operation interface corresponding to the data type to execute the target operation on the space in the nonvolatile storage area, and the space management modes and the space operation interfaces corresponding to different data types are different. According to the method, specific data processing is executed for the data type corresponding to the to-be-processed data, the space management difficulty of the nonvolatile storage area in the security chip can be reduced, the space arrangement efficiencyis improved, and in addition, due to the fact that the addressing range of the data is expanded, the method can be applied to management of the large-capacity nonvolatile storage area.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a storage space management method, apparatus, chip, device, and storage medium. Background technique [0002] As the size of the non-volatile memory area of ​​the security chip continues to grow, more and more applications are deployed on the security chip. When the space of the non-volatile storage area is frequently applied and released, fragmentation is more likely to occur, resulting in that the space of the non-volatile storage area cannot be effectively used. Therefore, a space management method is urgently needed to improve the Space utilization of non-volatile memory areas in secure chips. [0003] In the prior art, for the space management of the non-volatile storage area in the security chip, the usual practice is: when a space application request is received, the data to be stored are sequentially stored in the free space of the non-volatile storage a...
