Anonymous routing schemes in MANETs can be classified into on-demand or reactive routing methods, proactive routing methods and anonymous middleware routing method.A finer classification of reactive routing methods includes hop-byhop encryption and redundant traffic routing which either generate high cost or cannot provide full anonymity protection to data sources, destinations, and routes.An Anonymous Location-based Efficient Routing protocol (ALERT) was used to offer high anonymity protection at a low cost.Like other anonymity routing algorithms, ALERT is not completely bulletproof to all attacks.To prevent the occurrence of stronger and active attackers, we propose a Secure Cryptographic Based Mix-Zones Routing Protocol (SCMIX).The idea for mix-zones is to prevent the adversary from accessing the content of messages, including the Node's signatures.All legitimate nodes within the mix-zone obtain a symmetric key and utilize this key to encrypt all their messages while within the zone.
