Abstract

The invention discloses a validation method and a validation device of a chip with a secure booting function. The validation method of the chip with the secure booting function comprises the following steps that the validation device carrying BOOT procedures of a user reads a chip secret key used for verifying the chip with the secure booting function after the BOOT procedures guided by the user are started by the chip with the secure booting function and the BOOT procedures of the user are confirmed to be verified; the validation device judges whether the chip with the secure booting function is replaced or not according to the chip secret key; if the chip with the secure booting function is replaced, the chip of the secure booting function is stopped operating, a single board is prevented from starting, a network is prevented from being illegally embezzled and an operator network is prevented from being attacked, and therefore the safety of networks is guaranteed.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a chip verification method and a verification device with a secure startup function. Background technique

[0002] The traditional single-board secure boot technology is positive and executed sequentially. The core of the technology is a chip containing one-time programmable technology (English full name: One Time Programable, abbreviated as: OTP) storage space, and the chip Support security encryption algorithm.

[0003] In the prior art, the safe boot program of the single board is: the central processing unit (full English name: Central Processing Unit, CPU) starts its internal fixed user boot (English name: BOOT) program, and initializes, and After that, the CPU invokes the public key (English full name: Public KEY, abbreviated as: PKEY) to verify the integrity of the user BOOT program, and after determining that the user BOOT program is complete, it decrypts the user...
