Comparing NFS 2 and NFS 3 for secure authentication
Does NFS 3 provide a more secure authentication process when compared with NFS 2?
There is a major difference between V2 and V3 in that V2 uses a 32-bit file handle for identification and V3 uses a 64-bit file handle. This provides a greater degree of uniqueness for the file identification that can be important in the security scheme. Other than that, I don't see any other major differences.
