In this paper, based on researches and analysis for some common testing methods of randomness, a new testing method for randomness was proposed. This new method applied theories on kolmogorov complexity and wavelet transform to the randomness testing. This new method can be used to evaluate quality of random sequences generators and security of encryption algorithms.
In this paper, based on some researches on randomness of noise signals, the relations between removing deviation and correlation and improving randomness were found. In order to obtain desired true random sequences, we proposed to apply wavelet analysis to digital signals generated through physical generators to extract noise signals. These noise signals were just random sequences we wanted. Experimental...
This paper proposed an auto-analysis tool for security protocols. The tool is a formal analysis method based on Colored Petri Net (CPN for short) model. It analyses the semantics of security protocols based on CPN model and creates the relations between elements of security protocols and objects of CPN. And then the query functions of CPN ML from CPN Tools are used to describe security attributes...
