The avalanche effect is measured in terms of propagation criterion, correlation immunity, and algebraic immunity. Table 3 describes the fact that the cost of the attacks for our proposed RK-AES is much higher than the original AES due to the use of randomness with SRFG in several layer. The AES Key Schedule is used to produce a set number of round keys from the initial key. We have considered two attacks: related attacks and fault analysis attacks. The expression for the proposed combined function generator is given aswhere , four universal GATES: AND, OR, NOT, and XOR; L represents the expression length (number of terms in the combined function ); and represents the random combination. [20], In AES-NI Performance Analyzed, Patrick Schmid and Achim Roos found "impressive results from a handful of applications already optimized to take advantage of Intel's AES-NI capability".

As a result, corresponds to a function such that . and any affine any subspace , the restriction of to is the function given aswhere, can be determined by the with a function of variables. It means, the proposed solution is related attack resistant. Note: In VEX-encoded versions, VEX.vvvv is reserved and must be 1111b, otherwise instructions will #UD. Apart from using basic gates such as AND, OR, NOT, and XOR in the algorithms, researchers also have shown some specialized Boolean functions for the symmetric property. The authors show that a single random byte fault at the input of the eighth round of the AES algorithm is sufficient to deduce the block cipher key. We have compared our experimentation results of RK-AES with the original AES algorithm. This function is also using SRFG just before the output of the function as in Figure 4(b). The authors in the paper [9] have shown a differential faulty approach used in the mix column component of AES. Rahul Saha, G. Geetha, Gulshan Kumar, Tai-hoon Kim, "RK-AES: An Improved Version of AES Using a New Key Generation Process with Random Keys", Security and Communication Networks, vol. The authors declare that there are no conflicts of interest regarding the publication of this paper. Further, it may happen that the previously considered strong key is now made weak by the sophisticated technology or large computational abilities of the attackers. Combining the Faulty Sensitivity Analysis (FSA) and zero valued sensitivity, the proposed method of cryptanalysis is able to break code of the S-boxes in masked AES. It uses a function SubWord that takes these 4-byte words as input and applies S-box to each of these words. Section 4 shows the proposed modification for AES and in Section 5 we have explained its properties. For any random faulty key byte, the output of the layered SRFGs is always nonlinear and balanced. Another improved version of faulty attack on AES has been executed in the paper [13]. The input state matrix is processed by the various round transforms. A new kind of fault base attack has been proposed in [8] which uses zero valued sensitivity model for masked AES. As we have modified only the key expansion module, the results are derived only for key expansion only without involving the plaintext processing or transformations in round function. Cryptographic algorithms primarily depend on the structure of the algorithms and their corresponding functions [4]. [12] In August 2012, IBM announced[13] that the then-forthcoming Power7+ architecture would have AES support.
[28] A performance analysis using the Crypto++ security library showed an increase in throughput from approximately 28.0 cycles per byte to 3.5 cycles per byte with AES/GCM versus a Pentium 4 with no acceleration.

Section 6 analyses the security and Section 7 compares the related results.

(3)Ensuring high confusion and avalanche effect in key generation. Proposition 1.

The selection of key and its size is a major concerning factor in cryptography. The objective of the attacker is to recover . We have considered for our experimentation of RK-AES, , and n = 32 bit.

This algorithm provides the encryption for web security processes as used by different applications such as e-commerce, router applications, and WiFi security. To evaluate this property for our proposed key expansion we can consider the following. Therefore, Table 2 only compares the time taken for the key expansion process. is the elementary polynomial of degree with 2 variables. The authors show a fault model for a constantly underfed RISC CPU. Each cell in the state matrix is denoted as s with the index of row and column .
