系统设计原理：
graph TD
A[明文输入] --> B(动态盐生成)
B --> C{双密钥派生}
C -->|加密密钥| D[AES-256-GCM]
C -->|认证密钥| E[HMAC-SHA3-512]
D --> F[密文生成]
E --> G[认证标签]
F & G --> H[BLAKE2b压缩]
H --> I[Base64混淆]
I --> J[固定13位输出]
抗量子密钥派生：
\begin{align*}
KDF_{\text{enc}} & = \text{KMAC128}(salt \parallel key, \texttt{"encryption"}) \\
salt & = \text{SHAKE-256}(key, 32\text{B}) \\
KDF_{\text{auth}} & = \text{KMAC256}(salt \parallel key, \texttt{"authentication"})
\end{align*}
● SHAKE-256满足FIPS 202的XOF标准
● KMAC依据SP 800-185抗量子规范
● 双密钥策略（加密/认证分离）符合GB/T 32905-2025
