摘　　要：无线局域网主要采用电磁波作为信息传播的载体,信息在传输过程中很容易被窃听和干扰,因此数据在无线局域网中的安全传输成为当今网络时代迫切需要解决的问题。无线局域网本身的加密体制还不够完善,保密性上还存在一些欠缺。文章在无线局域网加密体制的基础上,采用非对称加密算法RSA与对称加密算法AES相混合的方式对消息进行双重加密,同时采用安全哈希算法SHA计算哈希值作为数字签名,以保证传输数据的机密性、完整性和不可否认性。文章还使用Java编程进行点对点的socket通信,在实验室局域网环境下进行多次测试,以验证方案的安全性和可行性。Because WLAN mainly uses electromagnetic wave as the carrier of information transmission, information can be easily eavesdropped and interfered in the transmission process. Therefore, the secure transmission of data in WLAN has become an urgent problem to be solved in the network era. The encryption system of WLAN is not perfect enough, and there are still some deficiencies in secrecy. On the basis of encryption system of WLAN, this paper uses the asymmetric encryption algorithm RSA and the symmetric encryption algorithm AES to encrypt the message, and uses the secure hash algorithm SHA to calculate the hash value as the digital signature, which ensure the confidentiality, integrity and non-repudiation of the transmitted data. This paper also uses Java programming for point-to-point socket communication, and several tests are carried out in the laboratory LAN to verify the security and feasibility of the scheme.
