A secure scheme against power exhausting
- 1. A Secure Scheme against Power Exhausting Attacks in Hierarchical Wireless Sensor Networks ABSTRACT: Security and energy efficiency are critical concerns in wireless sensor network (WSN) design. This paper aims to develop an energy-efficient secure scheme against power exhausting attacks, especially the denial-of-sleep attacks, which can shorten the lifetime ofWSNs rapidly. Although various media access control (MAC) protocols have been proposed to save the power and extend the lifetime of WSNs, the existing designs of MAC protocol are insufficient to protect the WSNs from denial of sleep attacks in MAC layer. This is attributed to the fact that the well-known security mechanisms usually awake the sensor nodes before these nodes are allowed to execute the security processes. Therefore, the practical design is to simplify the authenticating process in order to reduce the energy consumption of sensor nodes and enhance the performance of the MAC protocol in countering the power exhausting attacks. This paper proposes a cross-layer design of secure scheme integrating the MAC protocol. The analyses show that the proposed scheme can counter the replay attack and forge attack in an energy-efficient way.

EXISTING SYSTEM: • In existing, The B-MAC is an LPL based WSN MAC protocol, which decouples the sender and receiver with time synchronization. • The B-MAC protocol has no ACKs and the receiver has to listen and to wait for the long preamble ended from the sender. • This long preamble design of LPL based protocol consumes the major energy of both sender and receiver. • A dynamic session key policy (DSKP) was proposed based on a one time password (OTP) system to protect users during the authentication process and sessionkey agreement process. • It is hard to trace and detect. By using the counter indicated hash-chain algorithm, the DSKP is computationally cheap. DISADVANTAGES OF EXISTING SYSTEM: • Consumes more energy both sender and receiver
- 3. • DSKP is hard to trace and detect • Not suitable to the asynchronous LPL based MAC protocol PROPOSED SYSTEM: • In this project, a cross-layer design of secure scheme integrating the MAC protocol, Two-Tier Energy-Efficient Secure Scheme (TE2S), is proposed to protect the WSNs from the existing attacks based on our preliminary frameworks. • This cross-layer design involves coupling two layers at design time without creating new interface for information sharing at runtime. This project proposes a two-tier secure transmission scheme. This scheme uses the hash- chain to generate the dynamic session key, which can be used for mutual authentication and the symmetric encryption key. • The only computations of dynamic session key are the hash functions, such as MD5 or SHA-1, which are very simple and fast. By integrating with MAC protocol, there is no extra packet compared with the existing MAC designs.
- 4. • The two-tier design can check and interrupt the attacks at different check points. The combination of low complexity security process and multiple check points design can defense against attacks and send the sensor nodes back to sleep mode as soonas possible. ADVANTAGES OF PROPOSED SYSTEM: • Consume the less energy • Increase the network lifetime • Use the hash-chain to generate the symmetric encryption key
