STM32 Cryptographic Library
STM32 Cryptographic Library
Introduction
This manual describes the API of the STM32 cryptographic library (STM32-CRYP-LIB) that
supports the following cryptographic algorithms:
AES-128, AES-192, AES-256 bits. Supported modes are:
– ECB (Electronic Codebook Mode)
– CBC (Cipher-Block Chaining) with support for ciphertext stealing
– CTR (CounTer Mode)
– CCM (Counter with CBC-MAC)
– GCM (Galois Counter Mode)
– CMAC
– KEY WRAP
ARC4
DES, TripleDES. Supported modes are:
– ECB (Electronic Codebook Mode)
– CBC (Cipher-Block Chaining)
HASH functions with HMAC support:
– MD5
– SHA-1
– SHA-224
– SHA-256
Random engine based on DRBG-AES-128
RSA signature functions with PKCS#1v1.5
ECC (Elliptic Curve Cryptography):
– Key generation
– Scalar multiplication (the base for ECDH)
– ECDSA
These cryptographic algorithms can run in the series STM32F1, STM32 L1, STM32F2,
STM32F4, STM32F0 and STM32F3 with hardware enhancement accelerators.

surf特征点检测和匹配
surf算法的具体实现:
Surf算法原理
(1)、构建Hessian矩阵
(2)、构建尺度空间
图像的尺度空间是这幅图像在不同解析度下的表示,由式(4)知,一幅图像j(X)在不同解析度下的表示可以利用高斯核G(£)的卷积来实现,图像的尺度大小一般用高斯标准差来表示[6]。在计算视觉领域,尺度空间被象征性的表述为一个图像金字塔,其中,输入图像函数反复与高斯函数的核卷积并反复对其进行二次抽样,这种方法主要用于Sift算法的实现,但每层图像依赖于前一层图像,并且图像需要重设尺寸,因此,这种计算方法运算量较大,而SURF算法申请增加图像核的尺寸,这也是SIFT算法与SURF算法在使用金字塔原理方面的不同。算法允许尺度空间多层图像同时被处理,不需对图像进行二次抽样,从而提高算法性能。图1(a)是传统方式建立一个如图所示的金字塔结构,图像的寸是变化的,
