Network security protocol for constrained resource devices in Internet of things

Security protocols built on strong cryptographic algorithms to defeat attempts of pattern analysis are popular nowadays, but these algorithms consume a lot of processor's efficiency. So, devices with limited processor capabilities need some modified protocols. Billions of such devices, known as ‘smart objects’ are used in IOT (Internet of things). IOT is an interconnection of a large number of smart objects with low resources. WSN (wireless sensor network) which comprises of a large network of sensors and actuators with constrained capabilities also need resource efficient protocol to be implemented. Security, trustworthiness and privacy are major challenges to turn IOT into a reality. Absence of strong security protocols, attacks with malicious intent and malfunctions will outweigh the benefit of IOT components. Data integrity, identity management, trust management and privacy are four crucial obstacles in designing a secure IOT. To alleviate these challenges and obstacles, a security protocol that uses minimal processor capacity and facilitates targeted security benefits of IOT is proposed. This protocol counters most of security issues with existing IOT protocols and is robust against severe attacks. This protocol is unique in a way that it gives different bit-streams in a given authenticated session for same data which cannot be predicted by the transmitter itself and changes within nanoseconds. Also, a perfectly random signal to choose the bit-stream, in place of pseudo-random code algorithm is used. In V2V (vehicle to vehicle) IOT, an illustration of error correction in the key instead of lengthening the sent bit stream is also done.
