The rapid growth in the popularity of cloud environments requires special attention to be paid to the security of resources and data located in the cloud. The concept of trust and its properties, thanks to which it can be used to describe the interaction of components in cloud environments, are considered. Due to this, models based on this concept can be used to protect these cloud environments. Implementations of such models, namely: TNA-SL, InterTrust, ODTMF, Fuzz Art and their modifications, were considered. Requirements for them were determined, disadvantages and advantages were known. As a result, it was concluded that trust-based models can be used to protect cloud environments, but they require optimizations of both execution time and scalability for further use. It was also determined that it is worth paying attention to their use in federated cloud environments.
