Abstract

Cryptography is a process to transform data into unreadable format without eavesdropped by attackers. Cryptography basically includes encryption and decryption techniques in which the change of plain text into non-readable text is depicted as encryption and reverse of this encryption process is termed as decryption. In this paper, one new algorithm is proposed which is based on symmetric encryption. Encryption and decryption are done on the basis of ASCII values with transposition methods so that hackers could not attack on secret message. In this algorithm, secret key is generated by algorithm itself which is playing an important role in encryption and decryption. This paper is organized into four sections: First section introducing some basics of cryptography that must be in mind before do practice on secure communication. Second section presents the works that are done by different researchers in same area with their ideas. Third section proposes the algorithm and its flow of process with substitution and transposition level that make this method more secure. Forth section displays results after implementing the practical session on proposed method.
