Abstract

With the rapid advancement in the mobile and computing technologies, individuals have an inclination to depend more on them in varied range of situations. For ensuring the secured communication among the devices, privacy and security are the most prominent concerns. Accordingly, sophisticated preventive measures that support both secure storage and secret transfer has begun as the need of the hour. Several conventional techniques focuses on the data encryption and key generation approaches to attain reliability. However, there were some short-comings in key aspects such as privacy, key management, and flexibility. So as to overcome existing issues the paper implements a compact, constant-time, and fast improvised ChaCha 20 stream cipher mechanism for encryption and decryption. Likewise, the generation of key is employed with the use of Diffie-Hellman key exchange protocol scheme based on the string comparison. Thus, a secured transmission occurs with a reduced rate of execution time, decryption time, and key generation time. The performance evaluation is made in terms of encryption time, decryption time and the key generation time and are compared with the existing techniques to prove the superiority of this proposed scheme.
