Bit Level Encryption Standard (BLES): Version-I

Bit Level Encryption Standard (BLES): Version-I

In the present paper the authors have introduced a new symmetric key cryptographic method called Bit Level Encryption Standard(BLES) which is based on bit exchanging or bit reshuffling method. The authors have introduced a completely new bit level encryption method. Nath et. al has already developed bit manipulation method called NJJSAA where the authors mainly used bit level right shift, bit l...

Ultra Encryption Standard (UES) Version-IV: New Symmetric key Cryptosystem with bit-level columnar Transposition and Reshuffling of bits

The present paper is an extension of the previous work of the authors i. e. UES version-II and III. Roy et al recently developed few efficient encryption methods such as UES version-I, Modified UES-I, UES version-II, UES version-III. Nath et al developed some methods such as TTJSA, TTSJA and DJMNA which are most suitable methods to encrypt password or any small message. The introduction of mult...

Formalization of the Advanced Encryption Standard. Part I

In this article, we formalize the Advanced Encryption Standard (AES). AES, which is the most widely used symmetric cryptosystem in the world, is a block cipher that was selected by the National Institute of Standards and Technology (NIST) as an official Federal Information Processing Standard for the United States in 2001 [12]. AES is the successor to DES [13], which was formerly the most widel...

FPGA Can be Implemented Using Advanced Encryption Standard Algorithm

This paper mainly focused on implementation of AES encryption and decryption standard AES-128. All the transformations of both Encryption and Decryption are simulated using an iterativedesign approach in order to minimize the hardware consumption. This method can make it avery low-complex architecture, especially in saving the hardware resource in implementing theAES InverseSub Bytes module and...
