As wireless links are more vulnerable to attacks they are considered to be \"Un-trusted\" in terms of security, i.e. they are relatively simple to be hacked. One can easily gain access to confidential information. In this paper, the authors propose a secure transmission of information in wireless network by generating the key using Lagrange interpolation and polynomial equation through which only the shares will be transmitted over the network not the key. That key will be generated by the receiver by using those shares and node id known to the users and that generated key will be used in the algorithm known as New Tiny Encryption Algorithm (NTEA) which is a cryptographic efficient algorithm designed to minimize memory and maximize speed.
