In article <WARLORD.93Jan20204310@m1-115-7.mit.edu> warlord@MIT.EDU (Derek Atkins) writes: If you are trying to secure the network, and if you can trust the machines that you are trying to secure, then I suggest you look into Kerberos (comp.protocols.kerberos, or kerberos@mit.edu). It is based on DES, and uses shared secrets between entities to prove authenticity. It doesn't sound like you need real-time key distribution, which is something that Public Key algorithms have over secret-key algorithms, but if you have physical access to both machines, then you can place a shared secret on both machines and now that link is secure... I hope this helps. If you have any more questions, feel free to ask. My fiquestion is: how do I get kerberos source code, with all the DES code and hooks in place? Does your answer vary, depending on whether I'm in the US or the UK?
