Distributed systems increased the performance of a system by allowing applications to be processed in parallel. It helps us to share resources like printers, computers, storage facilities, data, files, web pages, networks, and thus it reduces the cost by shaing a single resource among several users instead of multiple resources. Since multiple machines communicate with each other through the network so they can be easily affected by the attacker and the full system should be corrupted. Users can access remote and local resources but they also may not aware of which machines their processes are running on. So, secure communiction of a distributed system is the most important issue. We need to analyze various vulnerabilities and can take proper protection of the system. In this paper, we discuss different architectural styles of distributed systems. Also, hold up different threads and protection mechanisms to get rid of these threads. The most focusing part of this paper is a summary of various distributed systems security. Here we hold up different distributed system security techniques like SSSE algorithm, BLCS architecture, ODIS algorithm, two eavesdropper model, dynamic cuckoo filter, etc. Finally, we summarize the full discussion like used methodology or architecture, advantages, disadvantages, accuracy, and future work in a table by which an author can easily gather knowledge about the summary of this paper. To better understanding, we show the result of various papers with a visual representation. I think it helps authors to know about security techniques and grow interested to work in this area.

“…Moreover, there is no need to have a higher clock speed, as discussed in the research [3]. Optimizing inter-core resource sharing distributed among software application components, presented by Schliecker et al [4], minimizes the computing power by avoiding concurrent accesses of wait-states to the shared resources with the expense of independent data processing and parallelization losses [5]. Thus, system architectures experiencing highperformance data processing and computation have been trending to be real-time mixed-criticality multicore processor platforms, as interpreted in Figure 1.…”

Over the decades, autonomous vehicles have been developed and qualified using variant single-core architectures. With the evolutionary trend of safety critical applications, innovative safety design methodologies have raised present requirements constraints and limitations to mitigate such design complexity deviations. The main objectives of this work are to investigate, evaluate and introduce an efficient safety-critical multi-cache multicore architecture, that is fully compliant with methods and principles of ISO 26262. Moreover, this paper presents new safety design choices applied to timing monitoring, temporal protection, runtime monitoring and services protection to overcome multicore processor challenges in runtime that eventually decay the worst case execution time and the interconnections (symmetric and asymmetric processors, critical timing, data coherency and synchronization predictability, core interconnects, etc.), as well as to tolerate real-time interference faults.

“…Mixed safety critical systems have been affecting with the coexistence, where software components (SWCs), even their sub-functions, usually have mixed-ASIL. Hence, interferences from Quality Management (QM) or lower-ASIL SWCs will be introduced [6][7][8][9]. They may corrupt higher-ASIL safetyrelated SWCs by means of information exchange interference, memory interference, real-time interference, and shared peripheral interference as represented in Figure 2.…”

Evolution to multicore architectures has been trending, as a result of the shift towards the nanoscale semiconductor industry. This lets multicore processor challenges arise in a way limiting their features. In present, mixed safety-critical systems in the automotive industry utilize multicore processors. These systems include a software code may reach millions of line-of-code needed for an emerging autonomy level. This implies more design complexity. Complying with ISO 26262 safety standard increases the complexity. This work proposes new safety mechanisms that overcome memory interferences that affect an Automotive Safety Integrity Level (ASIL) multicore architecture. New optimized double inverse redundant storage algorithms are presented to mitigate systematic memory data faults. Other safety mechanisms are introduced to overcome random faults in a memory. The proposed safety mechanisms have been investigated and evaluated for Aurix Tri-core and Renesas RH850 targets with lots of suggestions to have a fully compliant architecture with principles and methods of ISO 26262. Monte Carlo analysis has been performed for the proposed safety mechanisms diagnostic coverage which exceeds 99% considered as high.
