摘　　要：在海量节点环境中,网络拥塞风险因节点众多和数据传输需求大而增加,导致数据包传输产生延迟累积效应,导致数据包顺序混乱,使得数据在链路上无序流动,威胁链路密文加密的安全性。为此,提出海量节点即时通信链路超混沌加密算法研究。基于NTP原理对海量通信节点实施时钟同步校准,确保数据在加密链路上的有序流动,为后续加密同步性提供保障。结合相位分析法与混沌矩阵生成通信链路内的数据传输密钥,进一步优化密钥生成与加密过程的独立性,利用基于Logistics映射的超混沌算法,对已生成的密文实施加密编码,使得加密后的密文更难被破解,从而增强了加密系统的整体安全性。实验表明,利用所提方法实现的通信链路超混沌加密,具备较强的抗雪崩性,整体安全性更高,能够为海量节点即时通信提供强有力的安全保障。In the massive node environment,the network congestion risk increases due to the large number of nodes and the large demand for data transmission,resulting in the cumulative effect of delay in data packet transmission,resulting in the disorder of data packet order,making data flow disorderly on the link,threatening the security of link ciphertext encryption.For this reason,the hyperchaotic encryption algorithm for mass node instant communication link is proposed.Based on NTP principle,clock synchronization calibration is implemented for mass communication nodes to ensure orderly flow of data on the encryption link and provide guarantee for subsequent encryption synchronization.Combining the phase analysis method and chaos matrix to generate the data transmission key in the communication link,further optimize the independence of the key generation and encryption process.Using the hyperchaos algorithm based on Logistic mapping,the generated ciphertext is encrypted,making the encrypted ciphertext more difficult to be cracked,thus enhancing the overall security of the encryption system.Experimental results show that the hyperchaotic encryption of communication link implemented by the proposed method has strong avalanche resistance and higher overall security,and can provide a strong security guarantee for massive node instant messaging.
