Abstract - The Internet of Things (IoT) refers to the concept of connecting non-traditional computers and resources to the Internet, incorporating basic computing and communication technologies into physical objects for daily use. However, IoT faces challenges in terms of security and confidentiality, as current security mechanisms often lack critical specifications due to the limitations of CPU, memory, and energy resources in IoT devices. Additionally, centralized security architectures are not suitable for IoT, as they create a single point of attack and can be costly to defend against targeted attacks on centralized infrastructure. To address these challenges, there is a need to decentralize the IoT security architecture while considering resource constraints. we propose a blockchain sliding window (SWBC) architecture specifically designed for IoT applications, which modifies the conventional blockchain approach. The SWBC architecture utilizes previous blocks in proof of work to shape the next hash block, creating a sliding window mechanism.
