A-SAODV Homepage

This is the homepage of the SAODV secure routing protocol implementation created at CEFRIEL.

A-SAODV (Adaptive SAODV) is an implementation of the SAODV secure MANET routing protocol. SAODV is a security extension for the AODV routing protocol. Security is obtained using digital signatures and hash chains.

Features

Implements a slightly modified version of SAODV draft 04 using RSA as asymmetric cryptographic algorithm and SHA1 as hash algorithm.
Implements both single and double signature SAODV extension (can be selected at startup).
Nodes implement an adaptive behaviour (experimental, can be enabled at runtime).
Runs on Linux 2.6.x kernels (2.4.x should be ok, but untested).
Based on AODV-UU implementation version 0.8.1.
Uses libgcrypt as cryptographic library.
Cache of verified and signed RREP and RREQ messages.
Implemented as a user-space daemon.
Graphical key manager.
GPL license.

Overview

This implementation differs from SAODV draft 04 mainly for key management issues. Cryptographic operations are carried out by a dedicated thread in order to avoid blocking other messages processing. Intermediate nodes implement an adaptive behaviour in choosing whether to answer to route requests, in order to try to maximize network performance. More details here.
