Appeal No. 2006-2434
Application No. 10/197,148
BACKGROUND
Claim 1 is representative of the claimed invention and is
reproduced as follows:
1. A mobile ad-hoc network comprising:
a first node for generating an authentication request, said first
node having a first public key and a first private key associated
therewith; and
a second node having a second public key and a second
private key associated therewith;
said first node receiving a certificate of authenticity
responsive to the authentication request, the certificate of
authenticity being generated by a certifying authority and
comprising the second public key, the certifying authority having
a public authentication key and a private authentication key
associated therewith and generating the certificate of
authenticity using the private authentication key;
said first node decrypting the certificate of authenticity
using the public authentication key and verifying that the second
public key belongs to said second node based upon the decrypted
certificate of authenticity;
said first node sending challenge data to said second node
upon verification that the second public key belongs to said
second node;
said second node encrypting the challenge data using the
second private key and returning the encrypted challenge data
back to said first node;
said first node decrypting the encrypted challenge data
using the verified second public key and authenticating said
second node if the decryption of the encrypted challenge data
yields the original challenge data;
said first node sending a session key encrypted with the
second public key to said second node for use with subsequent
data transfers therebetween upon authenticating said second node.
