paper_title: Distributed Systems: Concepts and Design

paper_content:

Broad and up-to-date coverage of the principles and practice in the fast moving area of Distributed Systems. Distributed Systems provides students of computer science and engineering with the skills they will need to design and maintain software for distributed applications. It will also be invaluable to software engineers and systems designers wishing to understand new and future developments in the field. From mobile phones to the Internet, our lives depend increasingly on distributed systems linking computers and other devices together in a seamless and transparent way. The fifth edition of this best-selling text continues to provide a comprehensive source of material on the principles and practice of distributed computer systems and the exciting new developments based on them, using a wealth of modern case studies to illustrate their design and development. The depth of coverage will enable readers to evaluate existing distributed systems and design new ones.

paper_title: Achieving Distributed System Information Security

paper_content:

Distributed computing infrastructure's data storage subsystems are usually physically scattered among several nodes and logically shared among several users and (local) administrators. It is therefore necessary to provide users with adequate mechanisms and tools for information and data security management, especially in large scale systems since the complexity of the problem increases with the number of users and the amounts of data. In this paper we propose a solution based on a lightweight cryptography algorithm combining the strong and highly secure asymmetric cryptography technique (RSA) with the symmetric cryptography (AES). We describe a possible implementation of our solution going into details of all the algorithms and the mechanisms specified.

paper_title: Effect of Security Increment to Symmetric Data Encryption through AES Methodology

paper_content:

The selective application of technological and related procedural safeguards is an important responsibility of every organization in providing adequate security to its electronic data systems. Protection of data during transmission or while in storage may be necessary to maintain the confidentiality and integrity of the information represented by the data. The algorithm uniquely defines the mathematical steps required to transform data into a cryptographic cipher and also to transform the cipher back to the original form. Data encryptions standard (DES) use 64 bits block size as well as 64 bits key size that are vulnerable to brute-force, attack. But for both efficiency and security, a larger block size is desirable. The advanced encryption standard (AES,) that uses 128 bit block size as well as 128 bits key size was introduced by NIST In this paper, we showed the effect in security increment through AES methodology. To do this, we propose an algorithm which is higher secure than Rijndael algorithm (by comparing the key size) but less efficient than that. The difference of efficiency between Rijndael and our propose algorithm is very negligible. We explain all this term in this paper.
