Proposing an Encryption/ Decryption Scheme for IoT Communications using Binary-bit Sequence and Multistage Encryption

Currently for a secured communication to take place it has become important to use cryptography on both the sides i.e. encrypting data at sender's side later followed by decryption processes at the receiver's side. It is difficult to provide security against the attackers, since they can easily get the significant data by uncovering the encryption key. A lot of algorithms are being expounded for providing data security and most of these algorithms use random key generations, and perform arithmetic operations with the key. This paper puts forward a new encryption/decryption algorithm that is based on the ASCII, Binary-Bit sequence and further uses the XOR operation. It insinuates encryption at compound stages and the key is imparted by the user. In the proposed algorithm, the original data will be encrypted at multiple stages and a key will be made use for encryption of plaintext to cipher text; next same key will be put to use for decryption of cipher to plain text. The proposed algorithm comes under the category of Symmetric key algorithms.
