Security encryption chip

Abstract

The invention belongs to the technical field of computer chips, and particularly relates to a security encryption chip, which comprises an encryption chip, chip pins which are uniformly distributed are respectively arranged on two sides of the encryption chip, the chip pins are connected with the interior of the encryption chip, and a fixing plate is arranged at the bottoms of the chip pins. The top of the fixing plate is fixedly connected with a fixing pin, the fixing pin is adhered to the bottom of the encryption chip by adopting hot melting, the bottom of the fixing plate is fixedly connected with a plug pin, the plug pin is welded on a computer mainboard by adopting tin soldering, and an opening is formed in the plug pin. The chip pins are positioned on the to-be-installed circuit board through the positioning pins, meanwhile, the chip pins are welded to the to-be-installed circuit board through tin soldering, information between the to-be-installed circuit board and the encryptionchip can be transmitted and transmitted through the positioning pins, positioning of the encryption chip and the chip pins is guaranteed, and meanwhile the encryption chip and the chip pins can be borne.

Description

technical field [0001] The invention belongs to the technical field of computer chips, and in particular relates to a security encryption chip. Background technique [0002] The encryption chip is a general term for a type of security chip that integrates various symmetric and asymmetric algorithms and has a very high security level, which can ensure that the keys and information data stored inside will not be illegally read and tampered with. Its predecessor is the ESAM module in industries such as water and electricity meters, which is specially used for encrypted transmission of line data and safe storage of keys, so it is necessary to study it. [0003] When the existing encryption chip is installed, the chip pin 2 on the encryption chip 1 is often directly plugged into the circuit board, and then soldered together by soldering. In this way, it is easy to cause the chip pin 2 Insufficient soldering between the circuit board and the encryption chip 1 is installed on the ...

[0003] When the existing encryption chip is installed, the chip pin 2 on the encryption chip 1 is often directly plugged into the circuit board, and then soldered together by soldering. In this way, it is easy to cause the chip pin 2 Insufficient soldering between the circuit board and the encryption chip 1 is installed on the circuit board for a long time, the surface of the circuit board is easy to accumulate dust, and it is easy to cause the circuit board to pass through the water and dust in the air and the chip pin 2 on the fixed plate 3. A loop is formed between them, causing the encryption chip 1 to fail or burn out. Therefore, we propose a secure encryption chip
