摘　　要：为适应高速网络对大容量文件加解密速度的要求,提出了一种适用于多核环境下的AES保密模式——MACBC。MACBC模式利用多核计算机的多级缓存和共享内存等方面的特点,在保证安全性和对内存空间需求基本不变的情况下,把容量较大的待加密文件拆分为若干数据块,然后由多核心分别对这些数据块进行多线程加解密。实验表明,该模式加速效果明显,并且文件容量越大,加速比越高。To meet the requirements for encrypting and decrypting speed of high-capacity file in high speed network,an Advanced Encryption Standard（AES） security model based on multi-core technology named MACBC was presented.By using the characteristics such as multi-level buffer and sharing memory of multi-core computer,MACBC split the high-capacity file into some data blocks that were encrypted and decrypted in multi-threads,under the condition of security guarantee and basically invariable memory space.The experimental results indicate that acceleration effect of this model is obvious. And the larger the capacity of file is,the higher the acceleration ratio is.
