The edge-based Internet of Things (IoT) computing provides a new value for the consumer where the smart devices, objects, and appliances connected over the internet. The data generated from the smart IoT devices need to be securely processed. With the increasing rate of smart IoT devices, the existing addressing schemes and security protocols do not guaranty to perform well in all situations. This paper proposed a smart card based secure addressing and authentication (SCSAA) scheme by modifying the standard IPv6 protocol to mitigate the security threats in the IoT network. The proposed scheme has two folds; firstly, this scheme provides a unique way of addressing by assigning unique 64-bit interface identifier (IID) to smart devices/appliances and uniquely authenticates them in IoT network. Secondly, this scheme uses the secret session key to prevent the network from unauthorized access. Additionally, this work also evaluates the informal security analysis, formal security analysis using ROR model and AVISPA tool. The overall security analysis proves that proposed scheme protect the smart home IoT network from various vulnerabilities and attacks.

基于边缘的物联网（IoT）计算为通过互联网连接智能设备，对象和设备的消费者提供了新的价值。从智能物联网设备生成的数据需要进行安全处理。随着智能物联网设备的增加，现有的寻址方案和安全协议并不能保证在所有情况下都能正常运行。通过修改标准的IPv6协议以减轻IoT网络中的安全威胁，本文提出了一种基于智能卡的安全寻址和认证（SCSAA）方案。拟议的方案有两个方面。首先，该方案通过为智能设备/设备分配唯一的64位接口标识符（IID）并在IoT网络中对它们进行唯一的身份验证，提供了一种独特的寻址方式。其次，此方案使用秘密会话密钥来防止网络未经授权的访问。此外，这项工作还评估了使用ROR模型和AVISPA工具进行的非正式安全分析，正式安全分析。整体安全性分析证明，该方案可以保护智能家居物联网网络免受各种漏洞和攻击。
