PERFORMANCE ANALYSIS
This article conducts network security efficacy analysis
against the study [1], [16], [17] while also calculating the
time it takes for communication. Among the literature, this
study [16] employs a centralized management architecture
and proposes a medical data storage and transmission system that provides adequate network security mechanisms.
All of the devices must undergo identity verification via a
browser using their username/password. When transmitting
medical information, the system calls for the transport
layer security (TLS) mechanism to ensure transmission
security. The study [17] also uses a centralized management architecture and applies the elliptic curve cryptography to ward off malicious attacks. The simulation
environment for Table 2 is a 32-bit Intel Pentium IV 3.0-GHz
(Prescott) processor.
Table 2 can be used to compute identity verification, privacy protection, and data collection; the results can then be
employed to calculate how much time is needed for encryption/deciphering. Table 3 further demonstrates the network
security performance analysis on a health-care system based
on the estimated time of public-key cryptography, advanced
encryption standard (AES) symmetric encryption, and bilinear
pairing technologies [18]-[20]. As illustrated in Table 3, the
study [16] uses TLS for private communication and asymmetric
