【摘要】：随着网络的快速发展，信息安全越来越引起人们的关注。加密技术作为信息安全的重要技术，正发挥着重大的作用。基于分组的DES（Data EncryptionStandard）加密、解密算法在密码学中占有举足轻重的地位，而在此基础上改进的3DES加密、解密算法更是克服了DES密钥过短的缺点，有着广泛的应用。传统的加密工作是通过在主机上运行加密软件实现的。这种方法除占用主机资源外，其运算速度较硬件加密要慢，密钥以明文的方式存储在程序中，或者以加密的方式存储在文件或数字库中，重要数据（如个人密码PIN等）会在某一时刻以明文形式出现在计算机的内存或磁盘中，安全性较差。针对上述问题，本文提出一种基于ARM处理器的加密系统，，还系统通过独立于主机系统外的硬件加密设备实现加密、解密，所有关键数据的存储、运算都通过在ARM嵌入式硬件系统中实现，不占主机资源、速度快、安全性较高。通过在硬件设备中添加加密及解密功能，可使存储和传输的数据具有较高的安全性。本课题将致力于开发基于ARM的3DES文件加密及解密系统。
[Abstract]:With the rapid development of the network, information security has attracted more and more attention. As an important technology of information security, encryption technology is playing an important role. Encryption based on packet DES (Data EncryptionStandard), decryption algorithm occupies an important position in cryptography, and on this basis, the improved 3DES encryption, decryption calculation In addition to overcoming the shortcoming of the short key of DES, it has a wide application. The traditional encryption is implemented by running encryption software on the host. This method is slower than hardware encryption, and the key is stored in a program in a plaintext way, or stored in files or numbers in an encrypted way. In the word library, important data (such as personal password PIN, etc.) will appear in the memory or disk of the computer at a certain time, and the security is poor. In this paper, an encryption system based on ARM processor is proposed, and the system is encrypted, decrypted and decrypted by the hardware encryption equipment that is independent of the host system. The storage and operation of data are implemented in the ARM embedded hardware system, which does not occupy the host resources, fast speed, and high security. By adding encryption and decryption functions in the hardware devices, the storage and transmission data can have high security.
This project will focus on developing 3DES file encryption and decryption system based on ARM.
