In an embodiment, a communication method, using OFDM (Orthogonal Frequency Division Multiplexing), comprises transmitting and receiving packets between a first node and at least one second node, where each packet comprises a preamble and payload data. The method, performed by the first node, may comprise receiving packets from the at least one second node, and authenticating the at least one second node based on physical layer characteristics, i.e., on CSI (Channel State Information). The authenticating may be based on a plurality of preambles, which are extracted from a group of consecutively received packets.

Method of authentication of wireless communication based on physical layer security

The present invention discloses a pyrrolic amide compound shown as a formula I, or crystal forms thereof, and pharmaceutically acceptable salts, hydrates or solvates, wherein Ris selected from hydrogen, hydroxyl, cyano, halogen, carboxyl, C-Calkyl and the like; Ris selected from hydrogen, hydroxyl, cyano, halogen and the like; Ris selected from hydroxyl and the like; X is selected from group, m is equal to 0, 1, 2 or 3, and n is equal to 0, 1 or 2. The novel compound shown as the formular I provided by the present invention has high deacetylase inhibitory viability; and meanwhile, a method for preparing the novel compound in the present invention has the advantages of fewer steps, simple and convenient operation, safety, environment friendliness, high yield and the like and is very suitable for industrial application. 

Pyrrolic amide compound and preparation method and application thereof

A cross layer authentication method based on radio frequency fingerprint, it includes the following steps: S1. In the first time slot, the legitimate transmitter A sends the first packet to the legitimate receiver B, and then B identifies the first data packet by the upper layer authentication; S2. The legitimate recipient B extracts the RF fingerprint eigenvector of the legitimate sender A, and stores it in the memory of the legitimate receiver B; S3. In the next time slot, the sender X sends the second packet to the legitimate receiver B, and the legitimate recipient B extracts the RF fingerprint eigenvector of the sender X; S4. Set sample of the RF fingerprint eigenvector; S5. legitimate receiver B estimates the similarity between the RF fingerprint eigenvector of the sender X and sample of the RF fingerprint eigenvector. This invention is in advantage of low computational complexity, small delay and high precision.
