Encryption and Asymmetric Encryption Symmetric encryption: The same key is used for both encryption and decryption, such as the AES algorithm.Asymmetric encryption: Uses a pair of keys (public key + private key), where the public key is used for encryption and the private key is used for decryption. RSA is a typical representative. RSA Algorithm … Read more

To configure a device in OpenWrt to function simultaneously as an AP (Access Point) and STA (Client) for network bridging, the following steps must be completed. This configuration allows the device to connect to an upstream WiFi (STA mode) while providing wireless access to downstream devices (AP mode), enabling network extension or use when a … Read more
Abstract The openness of wireless signal transmission enables seamless data transfer in wireless communications, but it also increases the risks of attacks, eavesdropping, and interference. In recent years, due to the randomness of physical layer channels, there is potential for it to replace traditional cryptographic encryption schemes that rely on extensive computation, and related research … Read more
