A Security Information Transmission Method Based on DHR for Seafloor Observation Network

Area of Science:

• Oceanography
• Network Security
• Data Integrity

Background:

• Seafloor observation networks (SONs) require robust data integrity due to long-distance transmission and cyber threats.
• Existing frame check sequences (FCS) for data integrity have collision vulnerabilities and high computational costs.
• Resource-constrained environments in deep-sea monitoring necessitate efficient and secure data protection methods.

Purpose of the Study:

• To propose a novel, secure, and lightweight encryption scheme for data transmitted in seafloor observation networks.
• To enhance data integrity and reduce computational overhead compared to traditional methods.
• To address the security risks associated with data transmission in challenging deep-sea environments.

Main Methods:

• Developed a lightweight encryption scheme inspired by mimic defense and dynamic heterogeneous redundancy theory.
• Employed dynamic keys to encrypt data blocks, generating multiple, heterogeneous encrypted blocks for transmission.
• Utilized redundant information across multiple blocks for tamper detection and data recovery.

Main Results:

• The proposed scheme effectively increases data confusion, making it difficult for attackers to interpret or modify transmitted data.
• Redundant data blocks enable reliable identification and recovery of tampered information, ensuring data integrity.
• Experimental analysis confirmed reduced computational costs and improved security performance, suitable for resource-constrained SONs.

Conclusions:

• The novel encryption scheme provides a secure and efficient solution for protecting data integrity in seafloor observation networks.
• The dynamic key and heterogeneous redundancy approach offers a promising defense against data tampering in deep-sea monitoring.
• This lightweight encryption is well-suited for the demanding, resource-limited conditions of deep-sea data transmission.
