    I'm looking for some ideas about uniquely identifying that a DECnet
    network node is really the node it claims to be.
    
    This is for a new product with a fairly pressing need for security
    of this kind.
    
    I'm aware of the possibility of using the processor id, but how
    do I cope with �VAXes? 
    
    Nigel.

|     Perhaps you should pose this question in the DECnet-VAX notes file.
    It is located on BULOVA::DECNETVAX. Press KP7 to select this
    conference.

    You can't, without exchanging some secret info on a secure link.
    
    The ONLY way is to get a trusted party to carry some secret info.
    between the two nodes (eg: a password, encryption key, or whatever).
    
    This is a standard problem in cryptology, and the above result
    is fairly obvious.  See, for example, recent conversations on
    net.crypt.
