Peer To Peer Network

In previous work, we have proposed a service mechanism which automatically syncs the file resources among discrete mobile devices. The mechanism includes four modules. The role-based access control module (RBAC) defined an organization policy which constructs some rules for file resources accessing. The user identification module dispatches a user some specific role (s) with relevant permission (s) and constraint (s) to access organization file resources. The en-capsulation/de-capsulation module enforces the JXTA protocol to sync the file resource synchronization over a mobile peer-to-peer network. The knowledge base module stores various organization file resources in the proposed service mechanism. However, the service mechanism faces an important challenge about data security. How to securely sync organization file resources among discrete mobile devices is worth exploring. In this study, we enforces some cryptographic techniques, including advanced encryption standard (AES), Triple data encryption standards (Triple-DES), and data encryption standards (DES), to examine secure synchronization of organization file resources among discrete mobile devices. The experiment results show the proposed mechanism is secure to automatically sync file resources among discrete mobile devices. The contribution of this work is to solve data security issue in syncing organization file resources among discrete mobile devices. We also strengthen an organization mobility to acquire the file resources by a mobile device in anywhere.

Encryption Schemes

Rapid advances in embedded systems and mobile communications have flooded the market with a large volume of multimedia data. In this chapter, the authors present a summary of multimedia compression and encryption schemes, the way they have evolved over the decades. They first discuss the traditional approach to data encryption and their extension to video encryption. Next, they present the next generation algorithms for secure multimedia delivery, namely the Joint Video Compression and Encryption (JVCE) approach and give the reader an introduction to these approaches, the underlying assumption, advantages and limitations. The authors discuss the implementation of JVCE algorithms in light of requirements of mobile devices and propose how mobile agents can facilitate such an implementation.

Stored Information

An important part of ISO/IEC 27002 cyber security standard is the conservation of confidentiality that falls under its computer facility protection part which insures that the computer and its stored information can only be accessed by the authorized users. Securing mobile devices and mobile data to ensure the confidentiality, integrity, and availability of both data and security applications requires special consideration to be paid to the typical mobile environment in which a mobile computing device would be utilized. Protecting mobile devices includes multiple security technologies such as the right identification of its particular user, data encryption, physical locking devices, monitoring and tracking software, and alarms. This chapter reviews security-specific hardware and software applied to mobile computing and presents its advantages and drawbacks. Then it considers the concept of usability constraints in context of mobile computing security and introduces the seamless security method for identity proof of a particular user or device.

Background/Objectives: Recently, as the fourth industrial revolution has emerged, cloud computing services have been attracting attention for efficient use of Internet-based computing resources. Among the cloud computing services, even if the data processed by the mobile device is encrypted after being stored in the server, the confidential information can be leaked. Therefore, there is a need for the key generation for data encryption and decryption.Methods/Statistical analysis: In this paper, we propose a key distribution protocol that enables mobile devices to securely encrypt and decrypt keys in an efficient manner in a cloud environment. The main purpose of the proposed protocol is to maximize the efficiency and cost reduction of key generation, which can securely transmit and receive data, in a situation where the size of data used in the cloud environment and the storage location are increasing. As a result of the performance evaluation, the proposed method improved the authentication processing time by 4.1% on average compared with the existing protocol, and the average throughput rate of the server per unit time was 6.5%. In addition, the communication delay time between the authentication server and the mobile device improved by 9.3% on average, and the authentication overhead of the server was 11.5% lower than that of the conventional method.Findings: In order to solve this problem, the proposed protocol can solve the security problem of the mobile device because it can receive the authentication through the one - way hash function and the XOR operation using the encrypted data using the session key.Improvements/Applications: In future studies, we will apply the proposed protocol to the actual environment based on the results of this study and compare it with the results obtained from the theoretical studies.
