凭借行业内的技术、全自动化生产工艺、快速的供货渠道和良好的服务，金升阳推出的超小体积SIP封装LS05系列AC-DC电源必将延续LS系列的辉煌，继续微功率电源模块发展方向。安全性对工业物联网网络至关重要

有关信息安全和保护商业，工业基础设施免受网络攻击的意识正在提高。由于以前的封闭物联网网络和智能设备现在要连接到外部世界，准备就绪坚实可靠的安全策略势在必行。虽然存在众多的网络和数据安全模型，我们在本领域内关注的重点仍是加密功能，因为它是保证网络安全连接的*有效手段之一。

今天常用的一种基于网络的安全协议是IPsec。IPsec运行在互联网协议层次结构的第3层（L3），它可在路由网络中很好地工作。然而，因为它通常需要嵌入式或专用的独立加密引擎，实现起来成本很高。

工作在互联网协议层次结构的第2层（L2）工作的另一种替代方案是IEEE 802.1AE“MACSec”安全标准，它与“KeySec”认证密钥协商协议l 802.1af共同使用。虽然今天没有被广泛采用，但由于其在L2层可简便而高性价比地实现，它提供了一个更简单、更高效、可扩展的选择。

With the technology in the industry, fully automated production process, fast supply channels and good service, the ultra-small volume SIP package LS05 series AC-DC power supply launched by Jin Shengyang will continue the brilliant LS series and continue the development direction of micro-power power module. Security is critical to industrial iot networks

Awareness about information security and protecting commercial, industrial infrastructure from cyber attacks is increasing. As previously closed iot networks and smart devices now connect to the outside world, it is imperative to have a solid and reliable security strategy in place. While there are numerous network and data security models, our focus in this area remains on encryption capabilities, as it is one of the most effective means of ensuring a secure network connection.

One network-based security protocol commonly used today is IPsec. IPsec operates at Layer 3 (L3) of the Internet protocol hierarchy, and it works well in routed networks. However, because it usually requires an embedded or dedicated stand-alone encryption engine, it is expensive to implement.

An alternative to working at Layer 2 (L2) of the Internet protocol hierarchy is the IEEE 802.1AE "MACSec" security standard, which is used in conjunction with the "KeySec" authentication key agreement protocol l 802.1af. Although not widely adopted today, it offers a simpler, more efficient, and scalable option due to its simple and cost-effective implementation in the L2 layer.
