Safe starting method, embedded device, electronic device and storage medium

The invention discloses a safe starting method, embedded equipment, electronic equipment and a storage medium, and the method comprises the steps: in response to a starting signal of the embedded equipment, when a first encryption algorithm is an asymmetric encryption algorithm, extracting a first signature public key corresponding to a first mirror image from a mirror image key mapping table, and carrying out Hash operation to obtain a first Hash value; when the first hash value is the same as the root public key hash value, obtaining a second hash value according to the first encryption algorithm, the first signature public key and the first verification information; obtaining a third hash value according to the first hash algorithm, the first mirror image and the first intermediate information; and when the third hash value is the same as the second hash value, starting the first mirror image. According to the method and the device, each mirror image only corresponds to one piece of authentication informat
