The analysis of security problems of information exchange between the client and the "Smart Home" system is carried out. The priorities of information protection at the stage of information transfer are determined. The analysis of the proposed new wireless network standard Thread is carried out. Thread uses IPv6 and is built on the IEEE 802.15.4 standard, and its main advantage is security. At the same time, there can be up to 250 devices in the network, which are protected by encryption of the banking system level. But this is not enough to ensure the integrity of information. The use of a new encryption algorithm based on the current encryption algorithm based on the blockchain algorithm is proposed, thanks to the use of dynamically changing nonlinear bijective transformation (S-blocks) allows to avoid significant information security problems. This algorithm is used to ensure confidentiality (security during transmission), integrity (security during storage and modification only for authorized users) and authenticity (authenticity of the message source). And provides reliable information protection.
