In distributed operation, the authors uses different key management schemes, authentication and many trust models, but in wireless medium having reliability problem, hidden terminal problem etc. To provide authenticated nodes and secured environment is the important issue in MANET. Frequent path breaking, multi-hop wireless link between mobile nodes, self organization and maintenance are such properties that makes difficult to provide trust in MANET. This paper proposes the new trust scheme, which provides malicious free atmosphere for mobile ad-hoc network. This model first check the authenticity of nodes through challenge response method and then PKI certificate will be given to only authenticated nodes so as to enable the trusted communication platform. At last this paper give the comparisons of ACTP model with other existing trust model.
