Analysis of a Hybrid Cipher Algorithm for Data Encryption

Block and stream ciphers can be joined in order to obtain hybrid algorithms and the main idea of combining can be enhancing the security of the cipher. This paper is presented to illustrate a hybrid algorithm created by combining a block cipher algorithm, TripleDES (ECB mode) and a stream cipher algorithm, RC4. In the encryption mode, first the plain text is encrypted by TripleDES; then the particular cipher text is encrypted by RC4. In the decryption mode, first the cipher text is decrypted by RC4 and then by TripleDES to decrypt again and obtain the original text. Input (plain text) is given as a text file.
