....versus ALUs should reflect this. This paper will primarily focus on the problem of functional unit allocation determining the most appropriate quantity and ratio of functional units across the domain. We will use the 15 candidate algorithms of the Advanced Encryption Standard (AES) competition [12] to illustrate the issues that make component allocation difficult. While operator identification and optimization are both complex problems unique to coarse grain architectures, we will not address these issues here since the algorithms in the target domain often provide an obvious starting ....

The following section gives a general description of the AES. For more information, the reader can refer to [16, 10]. 2.1 General description The AES algorithm is capable of encrypting or decrypting data blocks of 128 bits by using cryptographic keys of 128, 192 or 256 bits. Fig. 1. General structure of AES. The AES key scheduling provides N r 1 round keys. The number of rounds N r is dependent on the key ....

Keywords: Advanced Encryption Standard, AES, Rijndael, BES, Algebraic Structure, Finite) Galois Field, Field) Conjugate, Multivariate Quadratic (MQ) Equations. 1 Introduction Rijndael [7, 8] was chosen as the Advanced Encryption Standard (AES) and published as FIPS 197 [21] on 26 November 2001. The AES is carefully designed to resist standard block cipher attacks [1, 18] Here we move our attention to a cipher that is an extension of AES, but which o#ers one particular advantage. All of the operations in this new cipher, the BES, are entirely described using very ....
....of size 2 that corresponds to the AES. We denote these three sets by A, B and BA respectively, so A State space of the AES Vector space F B State space of the BES Vector space F BA Subset of B corresponding to A Subset of F . 3 The Basic Structure of the AES We refer to FIPS 197 [21] for a full description of the cipher, but we list the significant steps here. We concentrate our attentions on a typical round; the first and last rounds have a di#erent (but related) form that is easily assimilated. We consider the basic version of the AES, which encrypts a 16 byte block using a ....

....of key recovery attacks on the AES. Keywords: Advanced Encryption Standard, AES, Rijndael, BES, Algebraic Structure, Multivariate Quadratic Equations, MQ, XSL algorithm. 1 Introduction There has been much recent speculation [3, 4, 9] about the potential for key recovery attacks on the AES [6, 8] and the possible work e#ort that might be required for any such e#orts. This speculation arises from two recent developments. A proposal for a new method of block cipher analysis known as the XSL technique [3, 4] An analysis of the AES in terms of a new cipher (the BES) in order to ....

....choose an encoding bit rate ( and the differentiated class satisfying (3.2) with maximal security complexity. Quantification of security complexity Nowadays advanced encryption algorithms, including the well known Data Encryption Standard (DES [65] and Advanced Encryption Standard (AES [66]) are block cipher algorithms based on Feistel structures and Substitution Permutation Networks (SPN) 23] Security complexity in these algorithms is achieved by many rounds of permutation and substitution. In particular, i) the algorithms must achieve one way property so that it is easy to ....

....ciphers has solidified the preeminence of both cryptanalysis techniques in the consideration of the security of all block ciphers. For example, many of the candidates submitted for the recent Advanced Encryption Standard process undertaken by the National Institute of Standards and Technology [6] were designed using techniques specifically targeted at thwarting linear and differential cryptanalysis. This is evident, for example, in the Rijndael cipher [7] the encryption algorithm selected to be the new standard. The concepts discussed in this paper could be used to form an initial ....

....block ciphers having 64 bit blocks, such as DES, triple DES, or IDEA [Lai and Massey 1991] should not be used if it is feasible for an attacker to collect about 2 32 samples, thus giving only marginal security to the overall scheme. However, newer block ciphers, such as some of the AES [National Institute of Standards and Technology (NIST) 1999] candidates, have 128 bit block sizes and are therefore more suitable in this case. 4.
