In this process,the EU has also formed and developed its National Security Strategy and issued four versions of security strategy reports in 2003, 2008, 2016, and 2022. The 2022 version of the EU security strategy(hereafter referred to as the New Security Strategy), for the first time, has identified Russia as a long-term and direct threat. Furthermore, it has paid increased attention to traditional security, especially the upgrading of military capabilities and has become more reliant on the United States and the North Atlantic Treaty Organization. In the future, the EU will accelerate the militarization process, exert all-out efforts to contain Russia, scrutinize neighborhood security, and increase its swing on China policy.展开更多

Generally, successive governments in India have followed the basic principles articulated in Kautilya’s Arthasastra and various security practices adopted during the British Raj. India’s national security strategies are based on an internal logic of geopolitical rivalry and changes in international scenarios, and they are strongly influenced by Hindu traditions and the “Sad-Dharma” purported by King Ashoka. The objective is to create an India-dominated security order in the South Asian subcontinent, which persistently builds its capacity and system as a “net security provider” in the Indian Ocean Rim. Moreover, India is vigorously expanding its network of influence in the Pacific region in an effort to become a world leading power that enjoys a high level of strategic autonomy.展开更多

These drones leverage the Internet of Things (IoT) to offer cross-location services for navigation. However, they are susceptible to security and privacy threats due to hardware and architectural issues. Although small drones hold promise for expansion in both civil and defense sectors, they have safety, security, and privacy threats. Addressing these challenges is crucial to maintaining the security and uninterrupted operations of these drones. In this regard, this study investigates security, and preservation concerning both the drones and Internet of Drones (IoD), emphasizing the significance of creating drone networks that are secure and can robustly withstand interceptions and intrusions. The proposed framework incorporates a weighted voting ensemble model comprising three convolutional neural network (CNN) models to enhance intrusion detection within the network. The employed CNNs are customized 1D models optimized to obtain better performance. The output from these CNNs is voted using a weighted criterion using a 0.4, 0.3, and 0.3 ratio for three CNNs, respectively. Experiments involve using multiple benchmark datasets, achieving an impressive accuracy of up to 99.89% on drone data. The proposed model shows promising results concerning precision, recall, and F1 as indicated by their obtained values of 99.92%, 99.98%, and 99.97%, respectively. Furthermore, cross-validation and performance comparison with existing works is also carried out. Findings indicate that the proposed approach offers a prospective solution for detecting security threats for aerial systems and satellite systems with high accuracy.展开更多

Based on the mechanism of physical attack to data remanence, the strategy intends to erase data remanence in memory cells once the power supply is removed, which disturbs attackers trying to steal the right information. Novel on-chip secure circuits including secure power supply and erase transistor are integrated into conventional SRAM to realize erase operation. Implemented in 0.25μm Huahong-NEC CMOS technology, an SRAM exploiting the proposed security strategy shows the erase operation is accomplished within 0.2 μs and data remanence is successfully eliminated. Compared with conventional SRAM, the retentive time of data remanence is reduced by 82% while the operation power consumption only increases by 7%.展开更多

In area of economics and trade, it pushes on the U.S.-Central Asian trade and investment framework agreement, focusing on developing trade in greater Central Asian region so as to encourage the regional countries to lower trade barriers and to advance reconfiguration of the regional countries and Afghanistan neighboring areas. In area of energy, it builds a greater Central Asian transportation network composed of highway, railway, natural gas-pipeline and electricity grid line to boom the regional trade and economy. In area of anti-terrorism, it strengthens security cooperation with the Central Asian countries. Meanwhile, it also pushes forward a multi-lateral security mechanism, increases economic aid, and promotes regional cooperation so as to achieve the regional lasting peace.展开更多
