Before a software package is released, all files in the software package are signed with
digital signatures. That is, after a message digest is calculated for all files in the software
package, the message digest is digitally signed using a private key.
After a software package with a digital signature is loaded to an NE through a media
such as the software release platform, the NE first verifies the digital signature of the
software package. That is, the NE uses a public key to decrypt the digital signature and
obtain the original message digest. Then, the NE recalculates the message digest and
compares the new message digest with the original one.
− If the two message digests are the same, the software package passes the
verification and can be used.
− If the two message digests are different, the software package fails the verification
and cannot be used.
The default WebUI login user name and password are admin and admin, respectively.
