Internet of Things (IoT) plays a prominent role in health-care of patients, which assist the physicians and patients through the assistance in effective decision-making and additionally, in the medical field, IoT plays a significant role in real-time monitoring of the patients. Even though the data provided by the IoT devices ensure the effective decision-making, the data is susceptible to the network attacks. Thus, the paper proposes an authentication protocol for enabling the secure data transmission in IoT based on three functions, such as encryption function, hashing function, and adaptive XOR function. The proposed authentication protocol is named as, Adaptive XOR, hashing and Encryption Key Exchange (AXHE) protocol, which is the combination of the functions, such as encryption function, hashing function, and adaptive XOR function. The protocol ensures the security in the communication through two successive phases, such as registration and authentication of the user, where the user name, password, public keys, private keys, and security factor are employed. The authentication is progressed as seven levels and whenever the security factor matches, the user is authenticated and the communication continues. The analysis of the proposed AXHE is performed using 50 and 100 nodes in the presence of DOS and black hole attacks, which acquires the detection rate, throughput, and detection delay of 0.3859, 0.32, and 6.535 s, respectively.

一种新的自适应XOR，基于散列和加密的身份验证协议，用于在物联网（IoT）中安全传输医疗数据

物联网（IoT）在患者保健中起着重要作用，它通过有效决策帮助医师和患者，此外，在医学领域，物联网在实时监控患者中也起着重要作用。病人。即使物联网设备提供的数据可以确保有效的决策，但数据仍容易受到网络攻击。因此，本文基于加密功能，哈希功能和自适应XOR功能这三种功能，提出了一种用于在IoT中实现安全数据传输的认证协议。所提出的身份验证协议被称为自适应XOR，哈希和加密密钥交换（AXHE）协议，它是加密功能，哈希功能和自适应XOR功能等功能的组合。该协议通过两个连续的阶段（例如，用户的注册和身份验证）确保通信的安全性，其中采用了用户名，密码，公共密钥，私钥和安全系数。身份验证按七个级别进行，只要安全系数匹配，就对用户进行身份验证，并继续进行通信。在存在DOS和黑洞攻击的情况下，使用50个节点和100个节点对提议的AXHE进行了分析，这分别获得了0.3859、0.32和6.535 s的检测速率，吞吐量和检测延迟。身份验证按七个级别进行，只要安全系数匹配，就对用户进行身份验证，并继续进行通信。在存在DOS和黑洞攻击的情况下，使用50个节点和100个节点对提议的AXHE进行了分析，这分别获得了0.3859、0.32和6.535 s的检测速率，吞吐量和检测延迟。身份验证按七个级别进行，只要安全系数匹配，就对用户进行身份验证，并继续进行通信。在存在DOS和黑洞攻击的情况下，使用50个节点和100个节点对提议的AXHE进行了分析，这分别获得了0.3859、0.32和6.535 s的检测速率，吞吐量和检测延迟。
