LoRaWAN network is a low power wide area network technology used to connect the Internet of Things
device and transfer data. To ensure the security of data when using LoRaWAN network, the following are some measures: Encryption: LoRaWAN network can use encryption algorithm
To protect the confidentiality of data. By using encryption algorithms such as the Advanced Encryption Standard (AES), data can be ensured against tampering or eavesdropping during transmission.
Authentication: In a LoRaWAN network, authentication is an important measure to ensure that a device connected to the network is a legitimate device. Unauthorized devices can be prevented from accessing the network by using authentication mechanisms such as device identification codes and keys.
Security Key Management: In a LoRaWAN network, security keys are used to encrypt and decrypt data. Security keys should be securely managed, such as using secure memory or using a separate security chip to store keys.
Prevent replay attacks: Replay attacks are a common form of attack where an attacker can steal transmitted data and resend them at a later time. To prevent replay attacks, mechanisms such as timestamps and sequence numbers can be used to ensure that transmitted data is not reused.
Monitoring: For LoRaWAN networks, monitoring network activities is one of the important measures to ensure data security. By monitoring network activities and analyzing abnormal traffic or activities, potential threats can be discovered in time and corresponding measures can be taken.
Overall, the security of a LoRaWAN network requires multi-layered measures to ensure the secure transmission of data. It is necessary to combine various measures such as physical security, network security and application security to improve the security of the network.
