“…For example, a user can download a program installer from the internet and verify its hash value to check whether the installer is complete and has not been corrupted or altered by a malicious attacker. Another use case is cryptographic hash functions in PGP [56,57], where a sender wants to send a message to the intended receivers, and the receivers want to verify the authenticity of the message. To ensure the integrity of the message and reduce computational costs, a digest of the message is computed and signed using the sender's private key, which is called the "signature," instead of signing the whole message.…”

Today, many organizations allow their employees to bring their own smartphones or tablets to work and to access the corporate network, which is known as a bring your own device (BYOD). However, many such companies overlook potential security risks concerning privacy and confidentiality. This paper provides a review of existing literature concerning the preservation of privacy and confidentiality, with a focus on recent trends in the use of BYOD. This review spans a large spectrum of information security research, ranging from management (risk and policy) to technical aspects of privacy and confidentiality in BYOD. Furthermore, this study proposes a policy-based framework for preserving data confidentiality in BYOD. This framework considers a number of aspects of information security and corresponding techniques, such as policy, location privacy, centralized control, cryptography, and operating system level security, which have been omitted in previous studies. The main contribution is to investigate recent trends concerning the preservation of confidentiality in BYOD from the perspective of information security and to analyze the critical and comprehensive factors needed to strengthen data privacy in BYOD. Finally, this paper provides a foundation for developing the concept of preserving confidentiality in BYOD and describes the key technical and organizational challenges faced by BYOD-friendly organizations.

“…In order to ensure the security of data, a unified and indiscriminate encryption storage method is currently used, which causes the waste of computing resources and time and fails to ensure high security requirements. Therefore, the storage of data must be balanced between security requirements and performance requirements [12].…”

Data security is a primary consideration when users choose cloud storage, and it is also an important factor that hinders the development of cloud storage. In order to meet the requirements of secure storage of user-differentiated data and guarantee a good user service experience, we propose a multi-level security task scheduling scheme that comprehensively considers the data security level, user service level, and task waiting time. The scheme adopts the idea of multi-level security. The security requirements of different security level data are ensured by the key strength of the cryptographic algorithm. The mapping between the data security level and the key length under the selected cryptographic algorithm achieves the task's priority order. Scheduling appropriate encryption modules to implement differentiated encryption is suitable for cloud storage environments where data sensitivity and importance are diversified.

“…A bitwise compression algorithm, however, is not constrained by lack of byte alignment. It will be able to see repeating literals or <length, distance> pairs (Kumar et al, 2010). For these reasons we are going to use zpaq as our for compressing our file fragments.…”

In this paper we propose novel approaches to the problem of classifying high entropy file fragments. Although classification of file fragments is central to the science of Digital Forensics, high entropy types have been regarded as a problem. Roussev and Garfinkel (2009) argue that existing methods will not work on high entropy fragments because they have no discernible patterns to exploit. We propose two methods that do not rely on such patterns. The NIST statistical test suite is used to detect randomness in 4 KiB fragments. These test results were analysed using an Artificial Neural Network (ANN). Optimum results were 91% and 82% correct classification rates for encrypted and compressed fragments respectively. We also use the compressibility of a fragment as a measure of its randomness. Correct classification was 76% and 70% for encrypted and compressed fragments respectively. We show that newer more efficient compression formats are more difficult to classify. We have used subsets of the publicly available 'GovDocs1 Million File Corpus' so that any future research may make valid comparisons with the results obtained here.
