F5 is an information hiding algorithm based on frequency domain. It has been widely used because of its high-capacity and robustness. In recent years, many scholars have engaged in the field. In this paper, It is proposed for a extential steganalysis of information hiding for F5(ESF). By cropping IPEG image more times along the oblique direction, ESF can deal effectively with abnormal data and get...
Automatic design of cipher algorithm is an ideal destination of cryptographists, but how to guarantee automatic cipher safe enough to be used in real application and designing time less enough to fit practical requirement are key problems. We first combine evolution computation and programmable chip to study cipher automatic design and hardware resource reconfiguration. We have studied main attacks...
