摘要: 隨著人類對海洋的探索與開發,水下網絡特別是水下通信技術逐漸成熟。水下通常使用聲吶進行通信,而水下聲吶通信信道具有傳輸速率低、誤碼率高、延時高和信道窄等缺陷,特別容易遭受惡意攻擊。因此,必須重視水下聲吶通信的安全問題。針對水下聲吶通信系統安全防護等級較弱的現狀,考慮水聲通信的獨特特性,概述了水下密碼裝備的未來發展趨勢。進而,從保護數據機密性角度出發,設計了一型密碼樣機和一種輕量級密碼算法,用于水下聲吶通信加密技術的演示驗證。測試結果表明:采用輕量級密碼算法的密碼樣機非常適合水下通信安全防護,能夠滿足通信速率要求,這為未來水下聲吶通信系統搭載密碼系統奠定了一定研究基礎。

Abstract: With the exploration and development of the ocean, the underwater network, especially the underwater communication technology, is gradually mature. Sonar is usually used for underwater communication, and underwater sonar communication channel is vulnerable to malicious attack because of its disadvantages such as low transmission rate, high bit error rate, high delay and narrow channel. Therefore, attention must be paid to the safety of underwater sonar communication. Aiming at the current situation that the security protection level of underwater sonar communication system is weak, considering the unique characteristics of underwater acoustic communication, the future development trend of underwater cipher equipment is summarized. Furthermore, from the point of view of protecting data confidentiality, a cryptographic prototype and a lightweight cipher algorithm are designed to demonstrate and verify the encryption technology of underwater sonar communication. The test results show that the cryptographic prototype with lightweight cipher algorithm is very suitable for the security protection of underwater communication and can meet the requirements of communication speed, which lays a certain research foundation for the future underwater sonar communication system to carry cryptographic system.
Key words : underwater;communication security;information encryption;lightweight cipher algorithm

21世紀以來,人類對海洋資源的開發利用以及海洋權益日益重視。海洋資源的勘探與開發、海洋環境監測、軍事對抗等現代海洋高新科學技術已成為各海洋大國研究的重要領域[1-2]。任何海洋技術的應用都離不開對海洋數據的采集與傳輸,水聲是海洋中無線信息傳輸的主要技術手段[3]。水聲通信及網絡可靈活地應用于不同的速率載荷、覆蓋距離、水體深度、網絡結構的情景,實現水下不同空間位置多個通信節點間的信息交互[4]。水聲通信即水下聲吶通信,由最初的水下聲吶探測衍生,現為水下聲吶通信探測一體化設備。現階段,其通信種類向多方向發展,有水下組網、潛漂標探測、遙控遙測等[5]。
