Performance Evaluation of Parallel International Data Encryption Algorithm on IMAN1 Super Computer

Abstract

Distributed security is an evolving sub-domain of information and network security. Security applications play a serious role when data exchanging, different volumes of data should be transferred from one site to another safely and at high speed. In this paper, the parallel International Data Encryption Algorithm (IDEA) which is one of the security applications is implemented and evaluated in terms of running time, speedup, and efficiency. The parallel IDEA has been implemented using message passing interface (MPI) library, and the results have been conducted using IMAN1 Supercomputer, where a set of simulation runs carried out on different data sizes to define the best number of processor which can be used to manipulate these data sizes and to build a visualization about the processor number that can be used while the size of data increased. The experimental results show a good performance by reducing the running time, and increasing speed up of encryption and decryption processes for parallel IDEA when the number of processors ranges from 2 to 8 with achieved efficiency 97% to 83% respectively.

Challenges of Blockchain Technology in Context Internet of Things: A Survey

“…Therefore, the exchange of information and data authentication in the IoT system is only done via the central server, connecting to cloud servers via the Internet, thus leading to security and privacy concerns especially with the growing number of IoT devices that will be used by 2025 [1][2][3] [15]. The third trusted party (central server) which guarantees safe and secure delivery between two parties is questionable in case of modifying the original data, delays in delivery, fraud, or vulnerable to system failures and hacking [4] [14][34] [35] [36], because with just a single point of control responsible for security many questions arise such as what if this third party becomes untrusted in terms of that the data may be updated or the system can be a victim of considerable hacked by cybercriminals [5] [6][7] [12]13]. Other questions can arise such as can we use the p2p communication paradigm to tackle the delay in communication as well as the issue of authentication of transactions.…”
