摘要: 对正交指纹,n-simplex指纹和OFFO指纹进行了理论分析和实验比较,通过推理和仿真表明:在附加噪声的平均共谋攻击下,OFFO抗共谋攻击性能最好,n-simplex次之,正交指纹最差.Abstract: This paper analyzes and compares the orthogonal,n-simplex and OFFO fingerprints. Through theory analysis and simulation experiment,the results show that OFFO outperforms the other two kinds of fingerprints,and n-simplex performs a little better than orthogonal fingerprints when suffering from averaging attack with additive noise.
