Mobile Ad hoc NETwork (MANET) is a collection of self-organizing mobile nodes without any help of centralized administration or established infrastructure. Due to this characteristic, MANETs are particularly vulnerable to various security threats. In addition, the design of most MANET routing protocols assumes that there is no malicious node in the network. Hence, several efforts and researches have been made toward the design of a secure and robust routing protocol for ad hoc networks. In this paper, we discuss the major attacks that can target the operation of ad hoc routing protocol. A detailed survey of the well-known secured ad hoc routing protocols for mobile ad hoc networks is presented. In order to analyze the existent solutions for securing ad hoc routing protocols in a structured manner, we have classified them into three categories: solutions based on cryptography, solutions based on one-way hash chain and hybrid solutions. This paper also gives a brief summary and comparison of various protocols available for secured routing in MANET.
