The present paper proposes a new cryptographic algorithm called Ultra Encryption Algorithm (UEA).Nath et al recently developed few efficient encryption methods such as UES version-I, Modified UES-I, UES version-II, TTJSA, DJMNA Nath et.al showed that TTJSA and DJMNA is most suitable methods to encrypt password or any small message.The name of the present method is Ultra Encryption Algorithm (UEA) as it is a Symmetric key Cryptosystem which includes multiple encryption, advanced bit-wise randomization, new serial feedback generation and bit-wise encryption technique with feedback.Evidenly, in the result section the authors have shown the spectral analysis of encrypted text as well as plain text to show the effectiveness of the bit-level algorithm.The spectral analysis reveal that the present module offers encryption that is free from repetitive text patterns and strong enough against the standard cryptographic attacks.
