“…В условиях многокритериального выбора целесообразно применить метод свертки взвешенных показателей (взвешенного среднего арифметического). Применение этого метода для сравнения криптографических решений предложено в работе [18]. Преимущество этого метода в том, что более высокие оценки получают те решения, которые имеют больше критериев с максимальной степенью соответствия.…”

“…Furthermore, the case study research confirmed the current best practice and expert opinion that thread pooling can have a significant positive impact on performance if the initial number of threads allocated early in the program is based upon factors such as the number of processors and the number of execution pipelines per processor. Finally, this work underlines the need for a systems approach to security as recommended in [10], [12], and [5]. This area is ripe for further research; the creation of a body of work has only just begun.…”

“…As illustrated in [5], the solution(s) are optimal and generally more efficient than the traditional static approach. The goal of optimization in DSOCARE does not end with selection of optimal cryptographic algorithms.…”
This paper presents the results of a case study research conducted by the author that investigated the performance impact of thread pooling in dynamic selection of optimal cryptographic algorithms in a runtime environment (DSOCARE), a cryptography framework proposed in the author's Ph.D. thesis. Using the advice, default, and pass-through priority modes in runtime optimal cryptographic algorithm selector (ROCAS) module of DSOCARE, eight cryptographic service requests with high and low security, speed, and priority Quality of Service (QoS) parameters were performed with and without thread pooling. The results of the performance test data showed that thread pooling increased the performance of cryptographic services by 70% in advice and pass-through priority modes. In the default mode, there was a throughput increase of 28%. The experiment also proved that the optimal number of threads in a thread pool is dependent on the number of processors and number of execution pipelines in each processor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
