全球进入以数字经济为主导的信息社会,数据成为关键生产要素,当今越来越多的数据被收集、处理和存储,分布式存储系统作为一种高效的存储架构在各数据领域得到广泛应用。然而,随着数据存储规模的不断扩大,分布式存储面临着信息泄露、数据破坏等更深层次的安全风险挑战。这些挑战将推动大数据分布式存储安全技术的创新变革,促进了国产密码技术和计算存储技术的融合。针对分布式存储节点数据信息泄露等安全问题,考虑到分布式存储加密性能与灵活性等需求,提出一种动态可重构加密存储解决方案。该方案设计了基于bio映射框架的高性能可重构密码模块,在此基础上构建多个配用不同密码算法的存储池,实现高性能硬盘数据加解密操作和存储池密码算法动态切换,并开发了具有密码算法和密钥远程在线加载功能的密码协议,满足各存储节点可重构密码模块统一管理与便捷安全更新需求,实现基于密码重构技术的数据细粒度加密保护和逻辑安全隔离功能。实验结果表明,该方案对存储数据进行加密保护与安全隔离的性能损耗约10%,可为分布式存储系统达到GB/T 39786-202《1 信息安全技术 信息系统密码应用基本要求》第三级及以上在设备和计算安全、应用和数据安全等方面提出的密码应用技术要求提供技术途径。
As the world embraces the digital economy and enters an information society
data has emerged as a critical production factor.The collection
processing
and storage of data have become increasingly prevalent.Distributed storage systems
known for their efficiency
are widely used in various data fields.However
as the scale of data storage continues to expand
distributed storage faces more significant security risks
such as information leakage and data destruction.These challenges drive the need for innovative advancements in big data distributed storage security technology and foster the integration of domestic cryptographic technology with computing storage technology.This work focused on addressing security issues
particularly information leakage
in distributed storage nodes.A dynamic and reconfigurable encryption storage solution was proposed
which considered the requirements for encryption performance and flexibility.A high-performance reconfigurable cryptographic module was designed based on the bio mapping framework.Based on this module
multiple storage pools equipped with different cryptographic algorithms were constructed to facilitate high-performance encryption and decryption operations on hard disk data.The scheme also enabled dynamic switching of cryptographic algorithms within the storage pools.A cryptographic protocol with remote online loading functions for cryptographic algorithms and keys was developed to meet the unified management and convenient security update requirements of reconfigurable cryptographic modules in various storage nodes.Furthermore
the scheme implemented fine-grained data encryption protection and logical security isolation functions based on cryptographic reconstruction technology.Experimental results demonstrate that the performance loss of this scheme for encryption protection and security isolation of stored data is approximately 10%.It provides a technical approach for distributed storage systems to meet the cryptographic application technology requirements outlined in GB/T 39786-2021 “Information Security Technology-Basic Requirements for Cryptography Applications” Level 3 and above in terms of device and computing security
application and data security.
