【摘要】：进入21世纪以来，膨胀的人口、恶化的环境、匮乏的陆地资源三大问题日益突出，发掘和可持续地利用海洋资源已经尤为重要。海洋动物在调节和维护海洋的生态平衡、繁荣和丰富生物形式的多样性等方面的作用是无法取代的。研究海洋动物对加强海洋环境保护工作有重要的实用价值，海洋动物的研究就显得非常重要。本文建立了海洋动物实验数据保密存储的系统，主要运用JSP开发语言和Tomcat6.0运行环境。当连接Web网站，进行网页请求时，JSP将这一请求转化成数据请求，并返回HTML页面。根据实际需求，完成了系统各功能模块的设计和实现。该系统的功能主要包括用户注册、用户信息管理、信息的录入、历史信息的管理四部分。不管是在网络上传输的信息还是存储在数据库中的数据，都有可能受到非法的攻击，，导致信息被截取、篡改甚至删除，本文为了增加系统的安全性，采用不同的加密技术对信息进行加密。由于MD5算法是单项加密，基本不可逆，加密性能高，用于用户密码的加密。非对称的RSA算法有两个密钥，即使拿到密文，不知道私钥，也不能进行正确解密，用于加密部分实验数据。在基于多个混沌算法的基础上，得到合成高维超混沌系统的一定规则，本文设计了一种基于六维复合Chen-Duffing超混沌算法。此算法中含有多个参数，密钥空间大，初始值敏感性强，大大提高了数字图像加密的安全性。
[Abstract]:Since the beginning of the 21st century, the problems of expanding population, deteriorating environment and scarce land resources have become increasingly prominent. It is particularly important to explore and make sustainable use of marine resources. The role of marine animals in regulating and maintaining the ecological balance, prosperity and diversity of biological forms is irreplaceable. The study of marine animals is of great practical value in strengthening the protection of marine environment, and the study of marine animals is very important. A secure storage system for experimental data of marine animals is established in this paper. The system mainly uses JSP development language and Tomcat6.0 environment. When connecting to the Web website, the Web converts the request into a data request and returns to the HTML page. According to the actual demand, the design and implementation of each functional module of the system are completed. The functions of the system include user registration, user information management, information input and historical information management. Whether the information transmitted on the network or the data stored in the database, are likely to be illegally attacked, resulting in information being intercepted, tampered with or even deleted, in order to increase the security of the system. Different encryption techniques are used to encrypt information. Because the MD5 algorithm is a single encryption, basically irreversible, encryption performance is high, used for encryption of user passwords. The asymmetric RSA algorithm has two keys, even if it gets the ciphertext and does not know the private key, it can not decrypt correctly, so it can be used to encrypt part of the experimental data. On the basis of several chaotic algorithms, the rules for the synthesis of high-dimensional hyperchaotic systems are obtained. In this paper, a six-dimensional composite Chen-Duffing hyperchaos algorithm is designed. This algorithm contains many parameters, the key space is large, the initial value is sensitive, and the security of digital image encryption is greatly improved.
