某位好胸弟已经把算法位置已经找到,便于大家分析,我直接把ida中反编译的代码贴出来吧,代码不多也就八百多行。
代码中有MD5,base64等比较简单的算法,这里不再分析。本文主要结束如何静态找出AES算法的关键信息。关键信息如下: 明文,密文,IV,密钥,填充方式,加密模式,数据块大小。
1.根据IDA插件FindCrpt找出sbox,根据sbox定位AES算法。首先浏览一遍代码。根据AES加密的流程,密钥扩展和明文都需要根据sbox的数据进行替换。而两者比较明显的区别:
(1)密钥扩展函数里字节替换后会进行异或操作。
(2)明文经过字节替换后会进行行移位操作。
根据此特征查看此处字节替换操作
很明显字节替换后,进行了行移位。可以判断 &v155 是要加密的内存地址
进入此函数
注意列混合的特征:某两个字节异或后会判断字节的最高bit位,如果最高bit位为1,则与0x1B异或。
根据此特征即可判断 j_innosecure_x11((int)v155) 为列混合。
接下来看下AES 解密流程,下图是AES128位的流程:
既然明文的字节替换,行移位,列混合都已找到,根据流程,这几个函数一定在一个循环之中,只要知道循环的次数,就可以知道加密的轮数。
AES128位 加密轮数为10
AES256位 加密轮数位14
根据此处判断
加密轮数位14,说明改AES算法的密钥大小为256位,即32字节。
现在已知AES的字节替换,行移位,列混合,那后面的自然是轮密钥加过程了,如图:
继续看下此过程,此处有个判断很关键if(v149<<31),当v149 即轮数为单数时,会执行 j_innosecure_x13((int)v180, (int)&v168),然后执行轮密钥加过程。
进入此函数,如图
好家伙,又有字节替换过程,且替换后直接异或操作,此处应该就是密钥扩展的一部分了。看下代码,将result数组看成4x4矩阵。
此处代码将矩阵最后一列循环移位一字节,然后再与第一列进行异或操作。
现在可以判断出该算法并不是一开始就将密钥进行完全扩展,而是每一轮扩展一次。
因为密钥块大小为256位,此函数每一次扩展32字节(roundkey[32]),轮密钥加过程中每一轮只与扩展密钥的16字节异或,所以第一轮与roundkey[0-15],第二轮与roundkey[16-32]异或,第三轮继续扩展密钥.....如图:
接着继续分析:
在AES算法中,执行10或14轮加密前,明文会直接执行轮密钥加过程,根据AES密钥扩展函数,扩展密钥的前16字节或32字节即为密钥。所以循环加密之前的那次轮密钥加过程即为明文与密钥进行异或,如图:
此图中在轮密钥加之前又有一次异或,可以判断此处是明文与IV异或。
分析到现在 AES的明文,密文,IV,密钥,密钥大小已经出来了,现在还差填充方式和加密模式。
继续分析,AES加密会将明文分割成16个字节,然后进行上图10轮或14轮的加密,所以在10轮或14轮循环加密之外必定有个分割明文的循环,如图
继续往上分析
分析此函数可知:
填充规则为PKCS7Padding,根据函数加密逻辑同时也可以判断加密模式为CBC,所以此AES的加密模式CBC,256位
密钥:
iv:
明文:
1.根据sbox,找到字节替换过程,如果字节替换后是异或操作,那此处即为扩展密钥的某部分。如果出现行移位操作,列混合操作即为明文的字节替换操作。
2.列混合操作的明显特征是,先异或,再判断字节最高bit位是否为1,如果为1再与0x1b进行异或,若函数内出现判断最高位和0x1b操作即为列混合操。
3.根据字节替换,行移位,列混合即可定位轮密钥加,这些操作一定在一个循环中,找到循环条件,知道循环次数,即可判断加密轮数,根据轮数即可判断密钥大小。
4.根据字节替换,行移位,列混合,轮密钥加循环,可以找到明文与iv异或和明文轮密钥加的过程(即明文与密钥进行异或)
如果明文没有与iv异或直接轮密钥加,即为ECB模式,若与iv异或那肯定不是ECB模式。
5.若明文大小大于16字节,在字节替换,行移位,列混合,轮密钥加循环外肯定有一个循环,用于分割明文,循环加密。一般为memcpy(a1,a2,0x10),
注意0x16 很关键,应该时刻关注0x16这个常数。通过这些特征找到明文地址,在分割明文循环之前,一定有填充函数,根据明文地址即可找到。如果填充0x16即为PKCS7Padding,如果填充为0即为ZeroPadding
6.对AES算法熟悉后,看循环次数,判断条件,memcpy(a1,a2,0x10)等下这些函数即可判断位置
