The problem is end-to-end security in proxy chaining envrionment. What
ever may be the protocol(CHAP or any EAP method) proxy server can see the
passwrod since it posses the shared secret key together with the radius
server residing one hop before and after itself. So there is threat of
theft of password. In order to overcome this threat we planned to use
public key cryptography as explained in previous email.
(request) (request) (request)
NAS ----------> Proxy1 ----------> Proxy2 ----------> Home
(reply) (reply) (reply) Server
<--------- <--------- <---------
To make it more clear lets take help of above figure. Here proxy1 and
proxy2 are threat to user password because both of these proxies can
decrypt the password field and see the password in clear text.
Thanks in advance,
Tahseen.
