Embodiment Construction

[0012] Specific embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, a new device debugging device that meets the ISO7816 protocol interface includes a first ESAM socket 1, a second ESAM socket 2, a PSAM module 3, a function selection switch 4, a data gating unit 5, and a power supply module 6. The common end of the function selection switch 4 is connected to the IC card interface 7, and the strobe end of the function selection switch 4 is respectively connected to the first ESAM socket 1, the second ESAM socket 2, and the PSAM module 3 through the data strobe unit 5 , the power supply module 6 is connected to the data gating unit 5 . The first ESAM socket 1 is a SOP16 socket. The second ESAM socket 2 is a SOIC8 socket. The PSAM module 3 is SIMF006A5K32-00R. The IC card interface 7 is inserted into the IC card socket of the active label, and the IC card interface 7 is connected wit...

Abstract

The invention provides a novel debugging device for an interface meeting an ISO7816 protocol. The novel debugging device comprises a first ESAM socket, a second ESAM socket, a PSAM module, a function selection switch, a data strobe unit and a power source module. A device or card to be debugged is arranged at the corresponding position of the debugging device, strobe is conducted on the corresponding function module, the debugging device is inserted in an IC card socket of an active tag, debugging can be conducted conveniently and fast through a simulation tool of the active tag, the debugging device has the advantages of being capable of sharing the operation process, sharing codes and the like, and a debugged unit is replaced conveniently. Interfaces of all types of devices or cards meeting the ISO7816 protocol are debugged uniformly, size debugging is facilitated, the ESAM, a PSAM card, an SIM card and a UIM card are packaged, and welding and other redundant operations in the debugging process are omitted.

Description

technical field [0001] The invention belongs to the field of ESAM commissioning devices, and in particular relates to a novel device commissioning device meeting the ISO7816 protocol interface. Background technique [0002] ESAM (Embedded Secure Access Module): The essence of the embedded security control module is a CPU card chip packaged with a DIP or SOP chip. It was first used in an IC card meter as a wallet to store recharge and consumption amounts, as well as other important parameters. At the same time, it has the function of identity recognition, and conducts two-way identity authentication with external cards. With the increasing emphasis on terminal security, it is widely used in various embedded terminals to realize safe storage of data, encryption and decryption of data, identification and authentication of terminal identity, copyright protection of embedded software, management of DRM digital copyright, etc. Function. In the field of intelligent transportation...
