It is assumed that this block contains an ECC signature, aswell as the console id and serial of the DSi that exported the file, as part of a Nintendo cert. Much like the Wii, the DSi carries with it a private ECC key that it can use to sign things, and a certificate signed by Nintendo that attests to the fact that the public ECC key belongs to a genuine DSi.
