Abstract

The invention discloses a safe starting method and device based on a Linux system, electronic equipment and a computer readable storage medium, and the method comprises the steps: reading a hash value of an RSA public key in OTP; verifying the signature of the uboot by using a hash value of an RSA public key in the OTP to obtain a first verification result; when the first verification result indicates that the verification is passed, verifying the head signature of the kernel to obtain a second verification result; when the second verification result indicates that verification is passed, a specified file in rootfs is verified, and a third verification result is obtained; and when the third verification result indicates that the verification is passed, verifying the file in the system. According to the method and the device, the problem that in the prior art, encryption processing, step-by-step decryption and verification need to be carried out on each partition mirror image for starting verification of the Linux system, and more consumption is caused to storage resources is solved, and the storage resources are saved.
