ADAPTIVE MODULATION WITH MULTI-LEVEL SECURITY USING SPARSE MATRICES

In the wireless sensor network system, wide ranges of techniques have been developed for securing the data before transferring to the concerned destination. Cryptography and modulation are distinct techniques that are used in wide range to protect the information from the attackers. In this slog we came up with a work of “Adaptive Modulation with Multi-Level Security for Networks”, in which the plain text is encrypted by using the newly proposed Encryption and Decryption Based on Sparse Matrices algorithm. This algorithm is a multi-staged encryption and decryption. By deploying encryption algorithm at the sender side message is encrypted before operating with modulation and demodulation algorithm. Encrypted message is then modulated through modulator. At the receiver side demodulation is performed followed by decryption operation. This approach results in the secure adoption of modulation with effective cryptography in unsecured channel more effectively.
