In this paper we present techniques to enhance security of geo-sharing which can be used in mobile ad-hoc networks. Our techniques are applicable and useful in a number of scenarios such as military operations in built-up areas where it is essential to securely know the location of friends. We have used Embedded Linux based PDA's equipped with on-board GPS to implement our secure geo-sharing techniques. We have used IPSec with automated key agreement (IKE) and WEP at the link layer to implement security of the geo-sharing information. In addition, we experimented with a number of encryption and authentication algorithms inlucding AES, DES, 3DES, Blowfish, Camellia, MD5 and SHA.
