Preliminary Security Analysis of the Multi-stage Protocol

This chapter presents a security analysis of the multi-stage protocol assessing its vulnerability to known security attacks. It shows that the multi-stage protocol can offer quantum level security under certain conditions. The material presented in this chapter is based on the authors’ work previously published in [12, 13].
