With the rapid growth of IoT, more devices are connecting to the internet, increasing data exchange and emphasizing the need for robust security. Future IoT devices, such as embedded systems using 5G and NB-IoT, may operate without traditional safeguards like firewalls or VPNs, making Zero Trust Network Access (ZTNA) a crucial solution for secure data transmission. This study implements a ZTNA-compatible security framework for IoT endpoints, preventing unauthorized access and ensuring data integrity. The proposed system integrates Linear Search (LS), Hash Search (HS), and an optimized Hash then Linear Search (HLS) method, comparing their efficiency in generating non-repeating random numbers to identify the best approach for IoT transmission. The results demonstrate improved data security and transmission efficiency, providing a practical ZTNA-compliant solution for IoT device communication.

摘要

With the rapid growth of IoT, more devices are connecting to the internet, increasing data exchange and emphasizing the need for robust security. Future IoT devices, such as embedded systems using 5G and NB-IoT, may operate without traditional safeguards like firewalls or VPNs, making Zero Trust Network Access (ZTNA) a crucial solution for secure data transmission. This study implements a ZTNA-compatible security framework for IoT endpoints, preventing unauthorized access and ensuring data integrity. The proposed system integrates Linear Search (LS), Hash Search (HS), and an optimized Hash then Linear Search (HLS) method, comparing their efficiency in generating non-repeating random numbers to identify the best approach for IoT transmission. The results demonstrate improved data security and transmission efficiency, providing a practical ZTNA-compliant solution for IoT device communication.
