Mobile Ad-hoc NETwork [MANET] adopt the property of self-organization with dynamic mobility. This open complex behavior with hybrid topology leads to a demand for high security against multiple attacks from malicious users. This paper contributes to the identification of node behavior and incorporates the feature of heterogeneous trust membership values among mobile nodes using a variable secured key along with trust metrics. Each mobile node carries a trust value TUFY, which is determined as a fuzzy value. These nodes also include the usage of an analytical security key SKi, which employs private key security for MANET nodes within a cluster. Experiments were conducted using the ns2 simulator and a hard-coded real-time approach to evaluate the network interaction quality and the identification of malicious nodes in TUFY.
