In this paper, a secret key generation scheme for a group of users based on wireless channel is presented in which legal nodes are connected under star topology. Instead of using the characteristics of the channel domain such as received signal strength (RSS), the channel phase is used in the proposed scheme; Because in channels with low mobility or channels with low dispersion that do not have a large entropy channel range, the channel phase can show significant changes. Based on this, in this article, a group key generation scheme based on channel phase is proposed. The proposed key generation scheme, compared to the similar scheme, needs less time intervals for execution and therefore has a high speed of the algorithm. As a result, the key production rate will be higher, which is very desirable. In the following, we will analyze and examine the proposed protocol in terms of some criteria such as the probability of generating the correct group key, scalability and vulnerable areas.
