Bhavikatti 1 Mallikarjun.Mugali 2 1,2Dept of CSE, BKIT, Bhalki, Karnataka State, India ABSTRACT In this paper, VHDL modeling of the SRAM module and State Machine Controller (SMC) module of RC4 stream cipher algorithm for Wi-Fi encryption is proposed. Various individual modules of Wi-Fi security have been designed, verified functionally using VHDL-simulator. In cryptography RC4 is the most widely used software stream cipher and is used in popular protocols such as Transport Layer Security (TLS) (to protect Internet traffic) and WEP (to secure wireless networks). While remarkable for its simplicity and speed in software, RC4 has weaknesses that argue against its use in new systems. It is especially vulnerable when the beginning of the output key stream is not discarded, or when nonrandom or related keys are used; some ways of using RC4 can lead to very insecure cryptosystems such as WEP . Many stream ciphers are based on linear feedback shift registers (LFSRs), which, while efficient in hardware, are less so in software. -

The Moral Character of Cryptographic Work⋆
The Moral Character of Cryptographic Work? Phillip Rogaway Department of Computer Science University of California, Davis, USA [email protected] December 2015 (minor revisions March 2016) Abstract. Cryptography rearranges power: it configures who can do what, from what. This makes cryptography an inherently political tool, and it confers on the field an intrinsically moral dimension. The Snowden revelations motivate a reassessment of the political and moral positioning of cryptography. They lead one to ask if our inability to effectively address mass surveillance constitutes a failure of our field. I believe that it does. I call for a community-wide effort to develop more effective means to resist mass surveillance. I plead for a reinvention of our disciplinary culture to attend not only to puzzles and math, but, also, to the societal implications of our work. Keywords: cryptography · ethics · mass surveillance · privacy · Snowden · social responsibility Preamble. Most academic cryptographers seem to think that our field is a fun, deep, and politically neutral game|a set of puzzles involving communicating parties and notional adversaries. This vision of who we are animates a field whose work is intellectually impressive and rapidly produced, but also quite inbred and divorced from real-world concerns. Is this what cryptography should be like? Is it how we should expend the bulk of our intellectual capital? For me, these questions came to a head with the Snowden disclosures of 2013. If cryptography's most basic aim is to enable secure communications, how could it not be a colossal failure of our field when ordinary people lack even a modicum of communication privacy when interacting electronically? Yet I soon realized that most cryptographers didn't see it this way. -
An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext
An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext By Isaac Quinn DuPont A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Faculty of Information University of Toronto © Copyright by Isaac Quinn DuPont 2017 ii An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext Isaac Quinn DuPont Doctor of Philosophy Faculty of Information University of Toronto 2017 Abstract Tis dissertation is an archeological study of cryptography. It questions the validity of thinking about cryptography in familiar, instrumentalist terms, and instead reveals the ways that cryptography can been understood as writing, media, and computation. In this dissertation, I ofer a critique of the prevailing views of cryptography by tracing a number of long overlooked themes in its history, including the development of artifcial languages, machine translation, media, code, notation, silence, and order. Using an archeological method, I detail historical conditions of possibility and the technical a priori of cryptography. Te conditions of possibility are explored in three parts, where I rhetorically rewrite the conventional terms of art, namely, plaintext, encryption, and ciphertext. I argue that plaintext has historically been understood as kind of inscription or form of writing, and has been associated with the development of artifcial languages, and used to analyze and investigate the natural world. I argue that the technical a priori of plaintext, encryption, and ciphertext is constitutive of the syntactic iii and semantic properties detailed in Nelson Goodman’s theory of notation, as described in his Languages of Art. I argue that encryption (and its reverse, decryption) are deterministic modes of transcription, which have historically been thought of as the medium between plaintext and ciphertext. -

Bias in the LEVIATHAN Stream Cipher
Bias in the LEVIATHAN Stream Cipher Paul Crowley1? and Stefan Lucks2?? 1 cryptolabs Amsterdam [email protected] 2 University of Mannheim [email protected] Abstract. We show two methods of distinguishing the LEVIATHAN stream cipher from a random stream using 236 bytes of output and pro- portional effort; both arise from compression within the cipher. The first models the cipher as two random functions in sequence, and shows that the probability of a collision in 64-bit output blocks is doubled as a re- sult; the second shows artifacts where the same inputs are presented to the key-dependent S-boxes in the final stage of the cipher for two suc- cessive outputs. Both distinguishers are demonstrated with experiments on a reduced variant of the cipher. 1 Introduction LEVIATHAN [5] is a stream cipher proposed by David McGrew and Scott Fluhrer for the NESSIE project [6]. Like most stream ciphers, it maps a key onto a pseudorandom keystream that can be XORed with the plaintext to generate the ciphertext. But it is unusual in that the keystream need not be generated in strict order from byte 0 onwards; arbitrary ranges of the keystream may be generated efficiently without the cost of generating and discarding all prior val- ues. In other words, the keystream is “seekable”. This property allows data from any part of a large encrypted file to be retrieved efficiently, without decrypting the whole file prior to the desired point; it is also useful for applications such as IPsec [2]. Other stream ciphers with this property include block ciphers in CTR mode [3]. -
RC4-2S: RC4 Stream Cipher with Two State Tables
RC4-2S: RC4 Stream Cipher with Two State Tables Maytham M. Hammood, Kenji Yoshigoe and Ali M. Sagheer Abstract One of the most important symmetric cryptographic algorithms is Rivest Cipher 4 (RC4) stream cipher which can be applied to many security applications in real time security. However, RC4 cipher shows some weaknesses including a correlation problem between the public known outputs of the internal state. We propose RC4 stream cipher with two state tables (RC4-2S) as an enhancement to RC4. RC4-2S stream cipher system solves the correlation problem between the public known outputs of the internal state using permutation between state 1 (S1) and state 2 (S2). Furthermore, key generation time of the RC4-2S is faster than that of the original RC4 due to less number of operations per a key generation required by the former. The experimental results confirm that the output streams generated by the RC4-2S are more random than that generated by RC4 while requiring less time than RC4. Moreover, RC4-2S’s high resistivity protects against many attacks vulnerable to RC4 and solves several weaknesses of RC4 such as distinguishing attack.
