“…In 2019, Qiao et al [26] presented a chaotic map-based authenticated key agreement scheme (AKAS) for strong anonymity in a multi-server environment to improve security. However, the main drawback of chaotic encryption algorithms is that they use floating-point calculations.…”

“…Therefore, A can capture these values to understand sent messages between U i and S j . According to the proposed protocol, β i , α i , and σ i are calculated as [21] Yes Yes Irshad et al [23] Yes Yes Mishra et al [25] Yes Yes Qiao et al [26] Yes No Proposed Yes Yes T 1 )) respectively using one-way hash function. Hence, A cannot find any vital information or value, which can be used to understand the communication between U i and S j , and these parameters are freshly computed for each communication session.…”

“…Table 3 shows the individual execution time for each operation. Thus, we consider the execution time of T ECM , T h(•) , T AES , and T CC to calculate the execution time of the proposed scheme, [21], [23], [25], and [26]. In the authentication scheme, the registration phase is executed once only, but the authentication and key agreement phase is performed whenever a user wants to get services from the server.…”

“…Hence, it is indispensable to have less execution cost in the authentication and key agreement phase than the registration phase. Table 4 describes the execution cost/time for recent schemes [21], [23], [25], [26], and the proposed protocol. We notice that the execution cost is very high in [23] and [26] during the authentication and key agreement phase due to the usage of high-cost operation (T CC ).…”

Moreover, the execution time is comparatively high in [21] and [25] because they specifically used ECC in the protocol design, and its execution time is high compared to the execution time of SHA-256.…”

The usage of different technologies and smart devices helps people to get medical services remotely for multiple benefits. Thus, critical and sensitive data is exchanged between a user and a doctor. When health data is transmitted over a common channel, it becomes essential to preserve various privacy and security properties in the system. Further, the number of users for remote services is increasing day-by-day exponentially, and thus, it is not adequate to deal with all users using the one server due to the verification overhead, server failure, and scalability issues. Thus, researchers proposed various authentication protocols for multi-server architecture, but most of them are vulnerable to different security attacks and require high computational resources during the implementation. To Tackle privacy and security issues using less computational resources, we propose a privacy-preserving mutual authentication and key agreement protocol for a multiserver healthcare system. We discuss the proposed scheme's security analysis and performance results to understand its security strengths and the computational resource requirement, respectively. Further, we do the comparison of security and performance results with recent relevant authentication protocols.
