Unlike regular wireless networks like Mobile Ad hoc NETworks (MANET) can be exploited instinctively devoid of necessitating any centralized administration or available network infrastructure. In such networks, the mobile nodes perform as relays to assist multi-hop communications and, in most cases, they are accountable for the entire networking functions. MANET is a very challenging task owing to the actuality that these systems may be subjected to attacks causing the network malicious. Among single- server and multi-server authentications, this paper intends to focus on multi-server authentication process in MANET or WSN or any heterogeneous network, which includes a secure protocol that provides a proper communication link between the nodes. In a single server network, both the credentials and authenticating procedure are handled by a single server. On the other hand, in a multi-server network, the credentials and authenticating procedure are handled by separate servers, and hence practically it is more robust against attacks. Hence, this paper develops a security protocol using Elliptic Curve Cryptography (ECC) in prime field. By adopting hash function, a secure way for key exchange is provided. Before transmitting the message from one node to another, it has to be ensured whether it is an authorized node or not. For authorizing purpose, a novel authenticating algorithm is developed based on two servers, a master server and normal server. Accordingly, the credentials and the processing steps are separated in such a way that compromising one of the servers never pose any threat to the whole authentication system. Initially, a node should register its credentials to the register centre, and those credentials are distributed to the server by a secure distribution algorithm where no hacking could be possible. The implemented technique is analyzed in terms of cost and security, and the results are obtained.

与常规的无线网络不同，像Mobile Ad hoc NETworks（MANET）这样的常规无线网络可以被本能地利用，而无需任何集中式管理或可用的网络基础结构。在这样的网络中，移动节点充当中继器以协助多跳通信，并且在大多数情况下，它们负责整个联网功能。由于这些系统可能遭受导致网络恶意的攻击，因此MANET是一项非常具有挑战性的任务。在单服务器和多服务器身份验证中，本文旨在关注MANET或WSN或任何异构网络中的多服务器身份验证过程，该过程包括安全协议，该协议可在节点之间提供适当的通信链接。在单个服务器网络中，凭据和身份验证过程都由单个服务器处理。另一方面，在多服务器网络中，凭据和身份验证过程由单独的服务器处理，因此在实践中它对攻击更健壮。因此，本文在素数场中开发了一种使用椭圆曲线密码学（ECC）的安全协议。通过采用哈希函数，提供了一种安全的密钥交换方式。在将消息从一个节点传输到另一个节点之前，必须确保它是否是授权节点。为了进行授权，基于两个服务器（主服务器和普通服务器）开发了一种新颖的身份验证算法。因此，凭证和处理步骤以这样的方式分离：损害其中一台服务器绝不会对整个身份验证系统构成任何威胁。最初，节点应将其凭据注册到注册中心，然后通过安全分发算法将这些凭据分发到服务器，在这种情况下，不可能进行黑客入侵。从成本和安全性两方面分析了所实施的技术，并获得了结果。
