An improved Merkle hash tree based secure scheme for bionic underwater acoustic communication
Abstract: Recently, bionic signals have been used to achieve covert underwater acoustic communication (UWAC) with high signal-to-noise ratios (SNRs) over transmission systems. A high SNR allows the attackers to proceed with their mischievous goals and makes transmission systems vulnerable against malicious attacks. In this paper we propose an improved Merkle hash tree based secure scheme that can resist current underwater attacks, i.e., replay attack, fabricated message attack, message-altering attack, and analyst attack. Security analysis is performed to prove that the proposed scheme can resist these types of attacks. Performance evaluations show that the proposed scheme can meet UWAC limitations due to its efficiency regarding energy consumption, communication overhead, and computation cost.

摘要：近来，在传输系统中仿生信号已用于实现具有高信噪比的隐蔽水声通信。高信噪比使得攻击者能实行恶意计划，导致传输系统易受恶意攻击。提出一种基于改进Merkle哈希树的安全方案，能够抵御当前水下攻击，具体包含重放攻击、伪造消息攻击、消息篡改攻击和分析攻击。进行安全性分析，证明所提方案能够抵抗这些类型的攻击。性能评估表明，该方案在能量消耗、通信开销和计算开销方面的效率可满足水声通信的限制要求。
