Asymmetric New Cryptography Algorithm Based on ASCII Code

Yaser M.A. Abualkas ^[2] | Arshed Raad Raheem

Abstract: Encryption is a process of generating secret text from the input text using a secret key and a encryption algorithm. Input text is referred to as plain text and the secret text generated is known as cipher text. Encryption algorithms are mainly divided into two categories which are symmetric key encryption algorithm and asymmetric key encryption algorithm. In Symmetric key encryption algorithm the same key is used by both sender and receiver but in asymmetric key algorithms use different keys for encryption and decryption. The keys are: Private Key and Public Key. The encryption key is public, decryption key is secret. Anyone can encrypt a message but only the one who knows the corresponding private key can decrypt it. The decryption key cannot be derived from the encryption key. Asymmetric key algorithms used for transmitting encryption keys or other data securely even when the parties have no opportunity to agree on a secret key in private. In this paper, we present a technique based on asymmetric key encryption algorithm which uses ASCII vales of input text to encrypt the data. Text data encryption techniques are very useful in data communication where one user want to send some secret messages to another users.
