An Efficient AES with Custom Configurable Encryption Algorithm Using Dynamic Keys for Secure Data Communication in Networks
2021
In this digital era, people are moving fast towards cloud and big data; hence, it becomes very important for the organization to encrypt the data. To enable secure data communication, the user needs different encryption algorithms. The encryption algorithms are RC4, RC5, SHA, DES,3DES, AES, etc. The mostly used algorithm is the Advanced Encryption Standard [AES]. This utilizes symmetrical keys, where the keys are shared between transmitter and receiver, i.e., the key will be easily hijacked by attackers. In this paper, we proposed the system working on three phases. Firstly, the custom replacement for input values like one character replaced by another character. Secondly, encrypt the data by using AES dynamic keys. To generate a key using 16 bytes, data frame is sending sequentially. Based on the order of this sequence, the key is changed dynamically with encrypted data and finally add padding bits to the ciphertext to provide more security to data or information.
