基于ZYNQ图像加密算法的设计与实现

Design and implementation of ZYNQ image encryption algorithm

随着通信网络规模不断扩大、业务种类日益繁多以及对通信安全性要求越来越高,传统密码算法已经无法满足现代网络通信需求。如今,众多的通用密码算法体系标准因其各自独特的算法优点而被广泛应用于多个行业,它们已经变成了确保数据传输安全性的关键工具。目前的高级加密标准算法(AES)在处理大数据量时会存在加密效果差、抗攻击性弱等诸多缺陷。针对以上问题,对传统AES加密算法进行了优化,在AES加密算法上加入了Arnold置乱算法,通过分块Arnold置乱提高了加密算法的效果和抗攻击性。最后在ZYNQ板进行了功能验证,结果表明,优化后的AES算法实现了预期的功能。

With the continuous expansion of communication networks,the increasing variety of services,and the increasing requirements for communication security,traditional cryptographic algorithms can no longer meet the needs of modern network communication.Nowadays,many common cryptographic algorithm system standards are widely used in many industries due to their unique algorithm advantages,and they have become a key tool to ensure the security of data transmission.The current advanced encryption standard(AES)algorithm has many defects when processing large amounts of data,such as poor encryption effect and weak attack resistance.In order to solve the above problems,this paper optimizes the traditional AES encryption algorithm,adds the Arnold scrambling algorithm to the AES encryption algorithm,and improves the effect and attack resistance of the encryption algorithm by smashing Arnold scrambling in blocks.Finally,the functional verification is carried out on the ZYNQ board,and the results show that the optimized AES algorithm achieves the expected effect.
