The Rijndael algorithm has been selected as the new Advanced Encryption Standard. Several JBits implementations of this algorithm are described which target the Virtex FPGA family. As illustrated by sample code, JBits provides a concise means of creating structured datapaths. JBits design abstractions include conventional ones (such as hierarchical modules, ports, nets and buses) and ones that ...

An AES algorithm can be implemented in software or hardware but hardware implementation is more suitable for high speed applications.AES is most secure security algorithm to maintain safety and reliability of date transmission for this key size is important. And here used AES-256 bit.The main goal of paper is AES hardware implementation to achieve less area and low power consumptions also to ac...

We put forth several simple candidate pseudorandom functions fk : {0, 1}n → {0, 1} with security (a.k.a. hardness) 2n that are inspired by the AES block-cipher by Daemen and Rijmen (2000). The functions are computable more efficiently, and use a shorter key (a.k.a. seed) than previous constructions. In particular, we have candidates computable by (1) circuits of size n poly lg n (thus using a s...

-Most companies and government agencies have a dire need for protecting sensitive information. Encryption, access restriction, and locking documents behind firewalls are some common techniques for protecting sensitive information. Encryption is an effective way for preventing an unauthorized person from viewing the content of a sensitive document. Nonetheless, once the document is decrypted for...

the security data transmission algorithm in cryptography is Advanced Encryption Standard (AES). The operation mix column consumed more power in the algorithm. In this paper the power consumption of mix column is reduced in order to achive the total power consumption of AES. Using a simple exclusive OR gate that is XOR gate pass transistor logic, the power can be minimized when compare to the ot...

This paper puts forward a safe mechanism of data transmission to tackle the security problem of information which is transmitted in Internet. The encryption standards such as DES (Data Encryption Standard), AES (Advanced Encryption Standard) and EES (Escrowed Encryption Standard) are widely used to solve the problem of communication over an insecure channel. With advanced technologies in comput...

Deniable encryption (Canetti et al. CRYPTO ’97) is an intriguing primitive that provides a security guarantee against not only eavesdropping attacks as required by semantic security, but also stronger coercion attacks performed after the fact. The concept of deniability has later demonstrated useful and powerful in many other contexts, such as leakage resilience, adaptive security of protocols,...

In cryptography, the advanced encryption standard (AES) is an encryption standard issued as FIPS by NIST as a successor to data encryption standard (DES) algorithm. The applications of the AES are wide including any sensitive data that requires cryptographic protection before communication or storage. This paper proposes extending generalpurpose processors with crypto coprocessor based on decou...
