Contriving Hybrid DESCAST algorithm for Cloud Security

Procedia Computer Science 2015年 54卷 47-56页

作者： Nandita Sengupta Ramya Chinnasamy University College of Bahrain Information Technology Department Manama Bahrain

Cloud computing has taken a major part in IT industry both for an individual and the organization. Primarily, it's used as infrastructure as a service, platform as a service, file storage, disaster recovery and backup. In cloud computing, protection of data in server and while in media is a challenging issue. Our proposed encryption algorithm Hybrid DESCAST has been designed to provide the security of huge volume of data sent through the media and the same will remain encrypted in the cloud sever. This cipher text will be decrypted only when the same is required to be used by the authenticated user. Problems of individual DES and CAST block cipher algorithm have been tackled by our proposed encryption algorithm. Complexity and Computation time for encryption and decryption for our proposed algorithm is higher than the individual DES and CAST algorithm. This paper is focused to provide security of data in cloud server, as well as for the data while transferring from client to cloud server and vice versa.

As the need for information security increases in our everyday life, the job of encoding/decoding for secure information delivery becomes a critical issue in data network systems. High-speed data encoding for cryptography is required especially when sending a large amount of important data with highspeed transmission. In order to accomplish the procedure more efficiently, previous research focused on implementing existing algorithms using hardware accelerators. In this paper, we discuss and propose the FPGA implementation of the SEED block cipher algorithm, which is a Korean national industrial association standard for secured systems. Our implementation, which is written in Verilog HDL, is synthesized and tested on a Virtex-V XC5LX 110T FPGA device. Our results show that the proposed fully pipelined design achieves high throughput and can support as high as 6.4 Gbps network speed. Compared to a full software implementation on the Intel Core 2 Duo 2.53 GHz processor, our implementation provides 34 times higher performance in terms of encoding/decoding throughput.

A UML 2.0 Profile to Model block cipher algorithms

Current mobile digital communication systems must implement rigorous operations to guarantee high levels of confidentiality and integrity during transmission of critical information. To achieve higher performance, the security algorithms are usually implemented as dedicated hardware functional units attached to the main processing units of the embedded communication system. To save hardware resources, the designer usually performs a number of manipulations in the cipher algorithm lying at the core of the confidentiality and integrity operations to implement a simplified version of it that is suitable to be efficiently used in an embedded environment. This paper describes an extension to UML 2.0 to model the structure of contemporary block cipher algorithms, with the ultimate goal of synthesizing representations in a hardware description language from these models according to a model-driven development principle. This automated process should alleviate design complexity and increase the productivity of the developer during experimentation with different design alternatives.

In this paper, we propose a new joint watermarking/encryption algorithm for the purpose of verifying the reliability of medical images in both encrypted and spatial domains. It combines a substitutive watermarking algorithm, the quantization index modulation (QIM), with a block cipher algorithm, the Advanced Encryption Standard (AES), in CBC mode of operation. The proposed solution gives access to the outcomes of the image integrity and of its origins even though the image is stored encrypted. Experimental results achieved on 8 bits encoded Ultrasound images illustrate the overall performances of the proposed scheme. By making use of the AES block cipher in CBC mode, the proposed solution is compliant with or transparent to the DICOM standard.

Power analysis attacks are non intrusive and easily mounted. As a consequence, there is a growing interest in efficient implementation of these attacks against block cipher algorithms such as Data Encryption Standard (DES) and Advanced Encryption Standard (AES). In our paper we propose a new technique based on the Kalman theory. We show how this technique could be useful for the cryptographic domain by making power analysis attacks faster. Moreover we prove that the Kalman filter is more powerful than the High Order Statistics technique.

MULTI-block CHAINING-BASED AUTHENTICATION MODE

Journal of Electronics(China) 2006年第4期23卷 564-568页

A fast authentication mode based on Multi-block Chaining (MBC) is put forward; and its security is proved. The MBC mode is for new generation block cipher algorithms. Its speed is about 13% faster than that of the authentication modes in common use (for example, cipher block chaining-message authentication code mode). The dependence test results meet the requirement. The MBC mode is complete; its degree of ava-lanche effect is about 0.9993; its degree of strict avalanche criterion is 0.992 or so. The frequency test results indicate that the output generated by the MBC mode has uniformity. The binary matrix rank test results imply that it is linear independent among disjoint sub-matrices of the output. Maurer’s universal statistical test results show that the output could be significantly compressed without loss of information. Run test, spectral test, non-overlapping template matching test, overlapping template matching test, Lempel-Ziv compression test, linear complexity test, serial test, approximate entropy test, cumulative sums test, random excursions test and random excursions variant test results fulfill the requirements of all. Therefore the MBC mode has good pseudo-randomness. Thus the security of MBC mode is verified by the way of statistical evaluation.

With the rapid progress of information technology, security becomes one of the key factors in information storage, communication and processing. For the reason of speed and security, the requirement for VLSI chips or modules that support data encryption and decryption increases rapidly. The design and implementation of a data ciphering processor (DCP) chip adopting block cipher algorithm is demonstrated in this paper. The cipher algorithm is qualified for commercial use. The plaintext, ciphertext and key are all 64-bit long. A top-down design flow is used in the implementation. Several methods are employed to enhance the security of the chip. A standard-cell library is also developed in the design. All the design and implementation of this DCP are performed in China. A 0.9um. double-layer-metal CMOS technology is adopted for manufacture. The chip achieves the required result in the first time implementation. The encryption/decryption processing speed reaches 40MBit/s.
