AI总结:

针对量子计算威胁,提出归一化基尼不纯度(NGI)验证AES各模式安全性,并比较ECB、CBC、CTR、CCM和GCM五种模式的性能,以加密图像实证分析。

摘要:

随着量子计算技术的成熟,许多加密方法逐渐面临来自量子计算的威胁。尽管Grover算法可以加速搜索速度,但当前研究表明,高级加密标准(AES)方法仍可通过增加密钥长度来增强安全性。然而,AES方法在实现中涉及多种模式,且并非所有模式都是安全的。因此,本研究提出一种归一化基尼不纯度(NGI)来验证每种模式的安全性,并以加密图像作为案例进行实证分析。此外,本研究主要比较了电子密码本(ECB)模式、密码分组链接(CBC)模式、计数器(CTR)模式、带CBC消息认证码的计数器(CCM)模式和伽罗瓦计数器模式(GCM)。

英文摘要:

With the maturation of quantum computing technology, many cryptographic methods are gradually facing threats from quantum computing. Although the Grover algorithm can accelerate search speeds, current research indicates that the Advanced Encryption Standard (AES) method can still enhance security by increasing the length of the secret key. However, the AES method involves multiple modes in implementation, and not all modes are secure. Therefore, this study proposes a normalized Gini impurity (NGI) to verify the security of each mode, using encrypted images as a case study for empirical analysis. Furthermore, this study primarily compares the Electronic Codebook (ECB) mode, Cipher Block Chaining (CBC) mode, Counter (CTR) mode, Counter with CBC-Message Authentication Code (MAC) (CCM) mode, and Galois Counter Mode (GCM).
