The Mobile Ad hoc NETworks (MANETs) having wireless and dynamic nature. MANETs are more susceptible to security attacks rather than wired networks. So they are vulnerable to security attacks from malicious node due to which it is important to detect malicious nodes to avoid attacks. In this paper, Certificate Authority (CA) provides its secret key to all nodes (normal). When node want to send data to other nodes Cluster Head (CH) broadcast R2mod N to all nodes and it gives challenge to that node whether it sending same data, if it sends RS mod N to CH with its secrete key which is provided by CA, then CH compares its data with itself data.
