Parallel Computing Of Cryptography : A Literature Review

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into

During this time Richard has showed himself as a promising young specialist and researcher. His major specialization is Applied Mathematics and Computer Science, but as an exception for academic achievements, Alex was allowed by our faculty to write his projects and degree thesis in the field of Cryptography under Computer Security and Applied Algebra Department.

            In the past decade, rapid advances have been made in the field of cryptography.  These advances have brought considerable

Numerous association and organizations in this world, including government and military store a lot of secret data on PCs and send essential information around the world to different PCs. With programmers out there, there ought to be an extraordinary level of security to ensure these information and individual data. As indicated by senate insight authorities, Cyber attack is one of the main dangers in the country so this needs to compass consideration.

The MD6 hash algorithm with the full name of the Message Digest Algorithm 6 is a cryptographic hash algorithm developed at MIT by a team led by Professor Ronald L. Rivest in response to the call for proposals for a SHA-3 cryptographic hash algorithm by the National Institute of Standards and Technology. MD6 is the latest of the “message digest” algorithm and is ideally suited to exploit the parallelism presented by today’s GPGPU architectures (Anon., n.d.)

These algorithms have their own positives and negatives. New algorithms are evolving day by day. Two algorithms listed below are discussed in this essay.

Due to emerging technologies such as big data, cloud platform and use of internet in day to day activities has led to security concerns for various end users. The transfer and storage of information is a crucial part in many business processes, industrial activities and also in military regime. The information could be in forms such as text data, video, audio, image or e-mail. Cryptography is a method to ensure the security and privacy of data transfer process. Data acquisition is the process of acquiring data accurately with minimum loss of signal being acquired and storing it for further use. Data acquisition and information protection is important in military applications. In the paper, a secure data acquisition system for military application is designed. The FPGA platform is used for implementation of the system design.

This section of paper includes why we need cloud computing as a security control tool against the cyber criminal activities and in how many ways it can be implemented. As we are living in a technical era, many aspects of our lives rely on the Internet and computers, including transportation, communications, government, medicine, finance and education. Consider how much of our personal information is stored either on our own computer or on someone else’s system.

From the viewpoint of data security, which has always been an important form of quality of service, Cloud computing surely poses new challenging security threats for number of reasons. Firstly, traditional cryptographic primitives for the purpose of data security protection cannot be straight accepted due to users loss control of data under cloud computing. Therefore, verification of correct data storage in the cloud must be attended without accurate knowledge of the whole data. Considering different kind of data for every user stored in the cloud and the requirement of long term continuous security of their data safety, the problem of checking correctness of data storage in the cloud becomes even more challenging.[1]

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)

Abstract— Data de-duplication is one of essential data com-pression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting de-duplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. The main motivation behind using this technique is making convergent encryption practical to capably and consistently manage a huge number of convergent keys and achieving competent and consistent key management in secure de-duplication. At we first introduce a baseline approach in which each user holds an independent master key for encrypting

Abstract— Crucial methods are employed to deploy the majority networks to acquire the data. Modern improvements stores, transfer data at higher rate. Traditional methods which provide security to the information. Using single encryption algorithms are more prone to issues and these are implemented without knowing its shortcomings. This proposed algorithms provides new step to avoid shortcomings. We resemble some famous algorithms as follows. Firstly, we create a new algorithms, In order to provide security issue and time constraint of operation. Secondly, We combine AES using multiplexing of keys, Improvement of DES key size and blowfish algorithm, then we encrypt data using the proposed algorithm. This can enhance the security and complicates the Encryption. In this paper we provide both the encryption and decryption that supports in real time application and algorithm has a practical value.5

In cloud computing, data security is the major issue. Security in single cloud is less popular than in multicloud due to its ability to reduce security risks. In this paper, we describe a new architecture for security of data storage in multicloud. We use two mechanisms-data encryption and file splitting. When user upload a file ,it is encrypted using AES encryption algorithm. Then that encrypted file is divided into equal parts according to the number of clouds and stored into multicloud. This proposed system enhances the data security in multicloud.
