As side-channel analysis and machine learning algorithms share the same objective of classifying data, numerous studies have been proposed for adapting machine learning to side-channel analysis. However, a drawback of machine learning algorithms is that their performance depends on human engineering. Therefore, recent studies in the field focus on exploiting deep learning algorithms, which can extract features automatically from data. In this study, we survey recent advances in deep learning-based side-channel analysis. In particular, we outline how deep learning is applied to side-channel analysis, based on deep learning architectures and application methods. Furthermore, we describe its properties when using different architectures and application methods. Finally, we discuss our perspective on future research directions in this field.

Developments toward a 'the end of the Cold War' are the main factor determining the situation in the Korean Peninsula. While all the combat resources of North Korea are systematically controlled and kept available for instant mobilization even in peacetime. South Korea is inferior to North Korea in terms of mobilization system and efficiency, exercise intensity and equipments. In sum, the South faces far greater restraints in wartime conversion capability than does the North. Mobilization refers to a nation's compulsory control, management and operation of its human and material resources for the purpose of national security. The total capability for safeguarding national security must be pursued by the continuous examination and complementation of our mobilization system and capability. This paper proposes an efficient management of national mobilization system that can be instantly operated on the whole in time of national emergency. Therefore, the actual operation of National Security Council is suggested to prepare operations against the emergencies and establish the foundation for national security.

Reliance on the Internet has introduced Voice over Internet Protocol (VoIP) to various security threats. A reliable security protocol and an authentication scheme are thus required to prevent the aforementioned threats. However, an authentication scheme often demands additional cost and effort. Accordingly, a security framework for known participants in VoIP communication is proposed in this paper. The framework is known as Randomness-Optimized Self-Securing (ROSS), which performs authentication automatically throughout the session by optimizing the uniqueness and randomness of the communication itself. Elliptic Curve Diffie-Hellman (ECDH) key exchange and Salsa20 stream cipher are utilized in the framework correspondingly to secure the key agreement and the communication with low computational cost. Human intelligence supports ROSS authentication process to ensure participant authenticity and communication regularity. The results show that with marginal overhead, the proposed framework is able to secure VoIP communication by performing reliable authentication.

Both access to healthcare services and income security in case of personal illness are being needed to achieve universal health coverage, which is enshrined in the human rights to health and social security and international standards on social protection. Income security acts on both the social determinants and the adverse consequences of ill health and thus would break the vicious disease-poverty cycle. The government is supposed to implement a demonstration project of sickness benefit in 2022 and to publicize its more specific blueprint for all workers. This study is to suggest basic principles and a framework to design a new sickness benefit for universal health coverage, which is based on reviews on previous studies, related issues, and institutional conditions. This is to provide a theoretical basis to promote further discussion and to support its decision-making.

The Internet of Things (IoT) is a new paradigm that connects physical and virtual objects from various domains such as home automation, industrial processes, human health, and monitoring. IoT sensors receive information from their environment and forward it to their neighboring nodes. However, the large amounts of exchanged data are vulnerable to attacks that reduce the network performance. Most of the previous security methods for IoT have neglected the energy consumption of IoT, thereby affecting the performance and reducing the network lifetime. This paper presents a new multistep routing protocol based on cellular learning automata. The network lifetime is improved by a performance-based adaptive reward and fine parameters. Nodes can vote on the reliability of their neighbors, achieving network reliability and a reasonable level of security. Overall, the proposed method balances the security and reliability with the energy consumption of the network.

The aim of this study is to examine the primary causes of security guard's stress by conducting a survey of 50 guards engaging in security companies in Seoul and Gyeonggido. The following results are attained by an inductive content analysis of conviction interview data through in-depth interview of qualitative study method. 1. Factors of stress related to personal problems. The stress by personal problems is resulted from two factors. One is the physical strength inferiority, which leads to negative thoughts, dismay, mental conflict and tension. The other is complex about not-specializing security, which causes discord with his/her supervisor or co-workers and a feeling of uneasiness. 2. Factors of stress related to human relationship. The stress due to human relations is constantly resulted from discord with his/her supervisor and inclined to be accumulated. The mental conflict is elated in feeling that the manager's instructions are not right. So this factor makes them want change of occupation. Also working conditions are different from those of their friends, which causes them not to spend a lot of time with their friends. 3. Factors of stress related to domestic life It appears that most security guards are under stress due to their spouses' discontent with a small number of wages. Also it is reported that male guards are under stress in case of unhappy conjugal relations. And security guard's life is restricted much more than that of workers in a general occupation because of standing ready for mobilization and 24-hour service. So some of male guards experienced an early symptoms of a morbid suspicion about their wife's chastity and are suffering from insomnia as an occupational disease.
