The End-to-End VPN security has an essential role especially in connecting smart objects in the Internet of Things (IoT) environments. It noted that security is a crucial issue in the End-to-End VPN approach. IPSec/IPv6 and OpenSSL are the most common VPN approaches used separately to secure smart IoT objects in different environments. These approaches have strengths and weaknesses. This paper addresses the development of a Hybrid End-to-End VPN security approach achieved by combining the IPSec/IPv6 and OpenSSL security approaches that can secure smart IoT objects in different settings. This proposed solution achieves the best combinations of complementary advantages of IPSec/IPv6 VPN approach and OpenSSL VPN approach and eliminates their shortcomings. Performance evaluation of the proposed Hybrid approach and the analysis of the comparison outputs of the performance of both IPSec/IPv6 VPN and OpenSSL VPN approaches assessed in terms of a group of standard measurements, for example, throughput, round-trip delay, and bandwidth consumption. The results of the simulation for the proposed solution demonstrate the correlation with acceptance levels compared to IPSec/IPv6 VPN, and OpenSSL VPN approaches.

端到端VPN安全性至关重要，特别是在连接物联网（IoT）环境中的智能对象时。它指出，安全性是端到端VPN方法中的关键问题。IPSec / IPv6和OpenSSL是最常用的VPN方法，分别用于保护不同环境中的智能IoT对象。这些方法各有利弊。本文致力于通过将IPSec / IPv6和OpenSSL安全方法相结合来实现混合端到端VPN安全方法的开发，该方法可以在不同设置中保护智能IoT对象。提出的解决方案实现了IPSec / IPv6 VPN方法和OpenSSL VPN方法的互补优势的最佳组合，并消除了它们的缺点。提议的混合方法的性能评估以及对IPSec / IPv6 VPN和OpenSSL VPN方法的性能比较输出的分析，这些评估是根据一组标准度量进行评估的，例如吞吐量，往返延迟和带宽消耗。与IPSec / IPv6 VPN和OpenSSL VPN方法相比，所提出解决方案的仿真结果证明了与接受水平的相关性。
