The invention discloses a method and a device for managing storage space in an intelligent card, belonging to the technical field of the intelligent card and being capable of distributing private spaces for different applications, as well as maintaining and managing the private space so as to satisfy the needs of users. The method for managing the storage space in the intelligent card comprises the following steps of: recording the distribution information of storage space management for each application configuration; and distributing corresponding private space for the application in the storage space of the intelligent card system in accordance with the recorded distribution information. Furthermore, the method also comprises the step of managing the private space distributed for the application in accordance with the recorded distribution information. The invention is applicable to occasions with the need of carrying out storage space management.
Description
technical field [0001] The invention relates to the technical field of smart cards, in particular to a method and device for managing storage space in a smart card. Background technique [0002] Smart Card (Smart Card) is gradually replacing the currently used photoelectric card, embossed code card, magnetic card, etc. due to its strong security features, and has become the mainstream personal security device. The smart card operating system (ChipOperating System, COS) is a proprietary operating system configured for smart cards. It is mainly used to transfer and transfer data from smart cards, control command execution, manage files, manage and execute encryption algorithms, etc. COS is a very critical component in smart card technology, and is the basis for smart card software security and all supported applications. [0003] In smart card technology, FLASH is widely used as a memory, and FLASH is a non-volatile and erasable memory. Among them, a storage unit block (block...
