Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] Functional Overview

[0028] Considering that the point-to-point communication method in the related art will cause the problem of low security, the present invention provides a point-to-point communication method based on near field communication and a near field communication device. In the solution of the present invention, the security module adopts a mixed key mechanism, and uses the receiver's public key to encrypt the key used for data transmission, so that there is no need to implement a shared key in advance. Since the adopted symmetric key decrypts data quickly, the efficiency is improved while ensuring the security of point-to-point data transmission. In addition, the above-mentio...

Abstract

The invention discloses a point-to-point communication method based on near field communication (NFC) and a near field communication (NFC) device, wherein the communication method comprises the following steps: a sender sets a safety module; the safety module is applied to a logic link control protocol (LLCP) layer and uses a first key to encrypt a second key and sends the encrypted second key toa receiver to notify the receiver that the second key is used when data are transmitted; the first key is a common key of the receiver and the second key is used for encrypting the transmitted data inthe communication between the sender and the receiver, and the safety module uses a first key to encrypt the data and sends the encrypted data to the receiver. Symmetrical keys are adopted with higher data decryption speed, thereby ensuring point-to-point data transmitting safety and enhancing efficiency. The safety module is applied to the logic link control protocol (LLCP) layer and is not arranged on an application layer for encryption, thereby achieving higher encryption safety.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a point-to-point communication method based on near field communication and a near field communication device. Background technique [0002] Near Field Communication (NFC) technology is a short-range wireless communication technology working at 13.56MHz, which evolved from the fusion of RFID technology and interconnection technology. It integrates contactless card reader, contactless card and peer-to-peer (Peer to Peer, also known as point-to-point) function on a single chip, so the near field communication service supports three working modes, namely, card emulation mode, reading Device mode and peer-to-peer communication mode, wherein, in the peer-to-peer communication mode, two physical devices with NFC function can directly transfer data to each other within a short distance, for example, to synchronize schedules, games, share transmission content, etc. [0003] NFC techno...
