A Newly Established Symmetric Key Encryption Algorithm for Small Amount of Data

During data transmission between the source and the destination in a computer network, the data is exposed to external modifications with malicious intentions. Cryptography is widely used to protect sensitive data from unauthorized access and modifications while on transit. There are various forms of cryptographic algorithms used in computer communications and are broadly divided into two types - symmetric key and asymmetric key. Symmetric key algorithms are the quickest and most commonly used type of encryption like Data Encryption Standard (DES), International Data Encryption Algorithm (IDEA), Advanced Encryption Standard (AES), etc. In symmetric key algorithms, a single key is used for both encryption and decryption. In this paper, a new symmetric key algorithm is proposed. The advantages of this new algorithm are also explained.
