    • Optical computing is a novel computing system based on optical unit which uses light as a primary means for information transmission and has a specific computing function. Compared with the traditional electronic computing technology, it has the advantages such as high speed, low energy consumption and high parallelism. However, there are several challenges on its way to widely commercial application, such as achieving device integration, miniaturization and portability. In recent years, with the rapid development of related technologies such as the silicon-based optoelectronic integration technology and the quantum technology, optical computing is expected to become a promising technical path to meet the urgent needs of high computing performance and low energy consumption brought by the development of artificial intelligence. Thus, it has become a research focus. First, this paper introduces the principle and development trend of the main technical paths of optical computing. Then, it analyzes the industrialization process of optical computing, the main application fields and existing challenges. Finally, it proposes the main development direction in the future.

    • With the continuous improvement of network speeds, the network processing overhead becomes increasingly significant. The in-network computing technology has become a key technology to offload the burden of hosts, release computing power of server, and solve network bottlenecks, which has attracted much attention in the fields of cloud computing and edge computing. First, starting with the needs of in-network computing, the background of in-network computing is described. Then, the development and industrialization of in-network computing technology is sorted out by focusing on the two aspects, namely, programmable switch and smart Network Interface Card (NIC). Finally, the application prospect of in-network computing is analyzed, and the application scenarios and the application value are proposed.

    • Enlightenment of ChatGPT to smart cities: discussion about evolution path for cities of the future
    • ZHU Gang, ZHANG Meixiang, SUN Haowen, LI Jiajing, ZHANG Liang, YANG Yunlong
    • Information and Communications Technology and Policy. 2023, 49(6): 71-78. DOI:10.12267/j.issn.2096-5931.2023.06.010
    • Abstract ( 351 ) HTML( 274 )   
    • The “city brain” has increasingly become a new hotspot in research on smart cities, helping to improve the intelligence level of cities, but the construction of smart cities still needs further improvement. With the vigorous development of new technologies such as new-generation Artificial Intelligence (AI), simulation modeling and business intelligence, sustainable business models and operation models are taken as the principles. AI capabilities are universalized throughout the life cycle of the city, and all aspects of the city are deeply integrated and coordinated. All those will deeply affect the construction planning and governance mode of the city and form the intelligent decision-making of urban operation and management. Cities can further evolve into intelligent, open and evolving ecology, so cities of the future are no longer out of reach.

    • Thoughts on improving rate of large number modular multiplication in RSA algorithm
    • JIA Binbin, WANG Zhongqing, FANG Wei
    • Information and Communications Technology and Policy. 2023, 49(6): 84-90. DOI:10.12267/j.issn.2096-5931.2023.06.012
    • Abstract ( 103 ) HTML( 56 )   
    • The core of RSA algorithm is large number modular multiplication. Improving its operation speed is not only of great significance to the improvement of RSA algorithm, but also will have a certain positive effect on the promotion of e-commerce if the speed can be achieved quickly and cheaply through application specific integrated circuit. Based on the study of Montgomery algorithm, this paper proposes a basic 2-Montgomery modular multiplication operation based on the parallel prefix adder architecture, and constructs a 1 024-bit Kogge-stone adder. The simulation results show that the proposed method can effectively reduce the delay time of operand and improve the efficiency of large number modular multiplication to a certain extent.
