Description

Technical Field

[0001] The utility model relates to the technical field of storage, and particularly relates to an encryption structure of a PSSD board. Background Art

[0002] PSSD uses solid-state drive technology to convert signals of the solid-state drive SATA or PCIe protocol into USB protocol signals through a bridge chip, and supports hot plugging. A PSSD consists of a solid-state drive (including a main controller chip, a storage unit, etc.) and a bridge chip. Compared with traditional mechanical external hard drives, PSSD is more lightweight in terms of product form factor and has the characteristics of shock resistance, high speed, and low power consumption of the SSD itself.

[0003] Existing PSSD technologies are divided into two types. The first is to convert the solid-state drive SSD into a USB protocol interface through bridging, and the second is a bridging method that integrates the bridge chip and the SSD control chip into a single PSSD controller chip. Each method has its own advantages. The first method only requires replacing the solid-state drive SSD to upgrade the capacity, etc., and the second method is natively integrated and is more compact in size due to high integration. However, the PSSD encryption technologies of these two methods are not essentially encryption. Instead, they achieve driving the bridge chip to work through fingerprints, Bluetooth, or input passwords, and the data of the solid-state drive SSD is not encrypted and protected.

[0004] Therefore, it is necessary to provide an encryption structure of a PSSD board to solve the above problems. Summary of the Utility Model

The encryption chip 2 and the Bluetooth module 4 are both arranged at the other end of the PCB circuit board 1. The encryption chip 2 is connected between the SSD board 6 and the connector 3. When reading the data in the SSD, it is first decrypted by the encryption chip 2, and then the data is transmitted to an external device to ensure that only legitimate users can access the data.

[0029] Refer to Figures 3 to 5 , In the embodiment of the present utility model, a bridging chip 7 and a power supply circuit 8 are further arranged on the PCB circuit board 1. The bridging chip 7 and the encryption chip 2 are soldered on the same side of the PCB circuit board 1. Power supply circuits 8 are arranged on both sides of the PCB circuit board 1. The power supply circuit 8 is respectively connected to the Bluetooth module 4, the bridging chip 7, the encryption chip 2, and the connector 3 to supply power to each component, ensuring the normal operation of the PSSD board.

[0030] Specifically, the design of the PSSD encryption board fully considers physical protection and signal optimization. Exposed pads 11 are reserved on both sides of the PCB circuit board 1. Ferrite beads 12 are arranged at both ends of the exposed pads 11, and a complete loop is formed by connecting the ferrite beads 12 to the ground, which is used to improve the anti-ESD electrostatic and anti-EMI electromagnetic interference capabilities.
