The issue is solved !

Dropbear didn't accept to open a SSH access because the pubkey saved in authorized_keys in right format !

My mistake is that until now, I used an old version of putty (<0.61) and the public keys created by PUTYYgen haven't a format identical with those generated by dropbear:

Before Putty release 0.61 , Putty inserts one "=" between encode pubkey and comment field! 
Whilst, Dropbear inserts only one space.

By confusion, I saved the dropbear pubkey in the old putty format.

So, the key wasn't been found when an SSH access attempt by NAS1 in NAS2 !
