“…We can also see some encryption modes as an instance of the FX construction. This is for example the case of the XTS mode [32], popular for disk encryption. It is generally used with AES-256 and two whitening keys that depend on the block number and another 256-bit key.…”

In symmetric cryptanalysis, the model of superposition queries has led to surprising results, with many constructions being broken in polynomial time thanks to Simon's period-finding algorithm. But the practical implications of these attacks remain blurry. In contrast, the results obtained so far for a quantum adversary making classical queries only are less impressive. In this paper, we introduce a new quantum algorithm which uses Simon's subroutines in a novel way. We manage to leverage the algebraic structure of cryptosystems in the context of a quantum attacker limited to classical queries and offline quantum computations. We obtain improved quantum-time/classical-data tradeoffs with respect to the current literature, while using only as much hardware requirements (quantum and classical) as a standard exhaustive search with Grover's algorithm. In particular, we are able to break the Even-Mansour construction in quantum timeÕ(2 n/3 ), with O(2 n/3 ) classical queries and O(n 2 ) qubits only. In addition, we improve some previous superposition attacks by reducing the data complexity from exponential to polynomial, with the same time complexity. Our approach can be seen in two complementary ways: reusing superposition queries during the iteration of a search using Grover's algorithm, or alternatively, removing the memory requirement in some quantum attacks based on a collision search, thanks to their algebraic structure. We provide a list of cryptographic applications, including the Even-Mansour construction, the FX construction, some Sponge authenticated modes of encryption, and many more.

“…MapReduce will be utilized as a part of our work to encode the huge data volumes and vital data utilizing the AES encryption algorithm as a part of XTX mode. The broadly utilized IEEE 1619-2007 standard is XEX-TCB-CTS (XTS) [22] mode in which key material for XTS-AES comprises of an encryption key and in addition a change key that is utilized to consolidate the coherent position of the data hinder into the encryption. XTS yields tend to deliver autonomous yields which prompt the parallelization of such procedure.…”

Data security is an important issue as far as storage of sensitive data is concerned. Hadoop is usually utilized for storage, large amount of data using its storage technology, namely Hadoop Distributed file System HDFS. Hadoop by default does not contain any security mechanism but as it has grown very much and it is the first choice of the business analyst and industries to store and manage data it is necessary to introduce security solutions to Hadoop in order to secure the important data in the Hadoop environment. Authentication, Authorization, Data Encryption, Security against various attacks are the key levels of data and information security in the Hadoop environment. Efforts have been made in order to attain each and every level of security over the period of recent years. Kerberos is one such effort in order to attain Authentication and Authorization and it succeeded in doing so, but with the attackers having new technologies and hacking tools attackers can easily bypass the security provided by Hadoop's Kerberos Authentication system and then the data at storage level is unencrypted can easily be stolen or damaged which is a big concern.Encryption of large data stored in HDFS is actually a process which takes a lot of time and this time consuming nature of encryption should be controlled by encrypting the data using a parallel method. This study discusses a new technique to perform encryption in parallel using AES-MR (an Advanced Encryption standard based encryption using MapReduce) technique in MapReduce paradigm..The time taken for Performing the encryption and decryption process is relatively less for user generated content. Results show that AES-MR encryption process is found to be faster with mapper function alone in comparison with running the encryption process under mapper function and reducer function. Here a new encryption scheme is given by the combination of AES and MapReduce in order to secure data in HDFS environment.The results generated for encryption on different data proves that the proposed technique is well suited for protecting user generated sensitive data deployed in the HDFS environment.

In recent years, security has been a common concern for the data in-transit between communication networks as well as data at rest in storage devices. The Institute of Electrical and Electronics Engineers P1619 Security in Storage Working Group proposed a standard for the security of static data. One of the components of this standard is the cryptographic protection of data on block storage devices. This standard uses Advanced Encryption Standard-XEX weakable block cipher with ciphertext stealing as a building block for the protection of data. Few field programmable gate array-based implementations of this mode that achieve sustainable throughput for block storage devices exist. This work proposes and demonstrates a different scheme that achieves better efficiency compared with current implementations.
