As Internet security threats continue to evolve, in order to ensure information transmission security, various encrypt and decrypt has been used in channel coding and decoding of data communication. While cryptography requires a very high degree of apparent randomness, Random sequences play an important role in cryptography. Both CA (Cellular Automata) and RC4 contain pseudo‐random number generators and may have intrinsic properties respectively. In this paper, a 3D visualization model (3DVM) is proposed to display spatial characteristics of the random sequences from CA or RC4 keystream. Key components of this model and core mechanism are described. Every module and their I/O parameters are discussed respectively. A serial of logic function of CA are selected as examples to compare with some RC4 keystreams to show their intrinsic properties in three‐dimensional space. Visual results are briefly analyzed to explore their intrinsic properties including similarity and difference. The results provide support to explore the RC4 algorithm by using 3D dimensional visualization tools to organize its interactive properties as visual maps.
