Secure Authentication

Mobile Multihop Relay (MMR) network is one of the emerging technologies, especially LTE-Advanced, WiMAX and the Smart grid communications. Ensuring security is one of the most imperative and challenging issues in MMR networks. Privacy Key Management (PKM) protocol is proposed to ensure the security measures in MMR networks. However, the protocol still faces several security threats, specifically Denial of Service (DoS), replay attacks, Man in the Middle (MitM) attacks and the interleaving attacks, which is termed as Medium Access Control (MAC) layer attacks. This paper proposed a modified version PKM protocol for both unilateral and mutual authentication, which is termed as Self-organized Efficient Authentication and Key Management Scheme (SEAKS) authentication protocol. This protocol ensures secure end-to-end data transmission using distributed hop-by-hop authentication and localized key management schemes with a very simple and efficient way.

Abstract Wireless Sensor Networks (WSNs) play a crucial role in developing the Internet of Things (IoT) by collecting data from hostile environments like military and civil domains with limited resources. The above applications are prone to eavesdropper due to cryptographic algorithms' weaknesses for providing security in WSNs. The security protocols for WSNs are different from the traditional networks because of the limited resource of sensor nodes. Existing key management schemes require large key sizes to provide high-security levels, increasing the computational and communication cost for key establishment. This paper proposes a Hybrid Key Management Scheme for WSNs based on Elliptic Curve Cryptography (ECC) and a hash function to generate key pre-distribution keys. The Key establishment is carried out by merely broadcasting the node identity. The main reason for incorporating a hybrid approach in the key pre-distribution method is to achieve mutual authentication between the sensor nodes during the establishment phase. The proposed method reduces computational complexity with greater security and the proposed scheme can be competently applied into resource constraint sensor nodes

DANETs, when compared to MANETs, have high network density and mobility over time. To maintain a secure communication over DANET, requires the knowledge of mobility and complex key management scheme based on the topology change. Operation of DANETs can be categorized into two types based on the activity: 1. Activities requiring small key length 2. Activities requiring large key length. For disaster detection and emergency rescues, key length with reduced size (partial authentication mechanism) is preferable, whereas military operation or critical data sharing needs larger key size (complete authentication mechanism). The challenges for key management in DANETs include the identification of which routing information to be trusted, legitimate nodes with the key for conducting safety communication. Maintaining existing key management schemes over network density change leads to a complex routing and data handling methods.. In this paper we propose a novel approach of homomorphic encryption scheme for data communication security by combining network protocol steganographic security management scheme which reduces the critical information leakage in DANETs. The proposed algorithm helps to identify the distributed denial of service attack and identification of malicious nodes. The malicious activities in a group are identified by analysis of link failures, retransmission information encoded over application layers. In order to assure reliability, encoded data is used as a means to monitor, detect and remove malicious nodes from routing table. We conduct simulation experiments by using network simulator 3.26, Open street Map to verify that our method achieves significant improvement in preventing critical data leakage in presence of malicious nodes.

Intelligent transportation systems (ITS) have always been an important application of Internet of Things (IoT). Today, big data and cloud computing have further promoted the construction and development of ITS. At the same time, the development of blockchain has also brought new features and convenience to ITS. However, due to the endless emergence of increasingly advanced types of attacks, the security of blockchain-based ITS needs more attention from industry and academia. In this paper, we focus on exploring the primitives in cryptography to guarantee the security of blockchain-based ITS. In particular, the authentication, encryption, and key management schemes in cryptography are discussed. Furthermore, we propose two methods for achieving the threshold key management in blockchain-based ITS. The proposed threshold key management scheme (with threshold t ) enables various stakeholders to recover a secret if the number of participated stakeholders is at least t . It should be noted that the proposed threshold key management scheme is efficient and secure for multiple users in blockchain-based ITS, especially for the data-sharing scenario.

Key Management Scheme

Wireless sensor networks are widely applied in various applications. But due to the resource-constrained sensor nodes and the malicious attacks, the traditional key management schemes are not suitable for the network. Contraposing the particularities, many relevant key management schemes are developed for WSNs the network. Based on the framework of WSNs, existing schemes can be classified into two categories: flat distributed architecture and hierarchical architecture. In this paper, a hybrid key management scheme for wireless sensor network is proposed by combining the distributed architecture and the hierarchical architecture. Based on the modified version of Dus matrix construction, this scheme can apply in WSNs with the network topology changes. Compared with existing key management schemes, this scheme can provide sufficient security, nicer key connectivity and low key storage overhead.

Security has been one of the most critical concerns for wireless sensor network (WSN) systems in recent years. Application of WSN has faced criticism in several fields due to limited flexibility and security in the long term. This study aimed at reviewing the dynamic key management schemes for Heterogenous WSN systems to determine efficient management schemes. Applicability of notable schemes such as Basic scheme, and hybrid schemes under dynamic key management depends majorly on the central key controller presence

The purpose of this paper is to present an outlier detection mechanism for hierarchical key management which utilizes hybrid (public and private) key management scheme for implementing lightweight cryptographic primitives in hierarchical MANETs. Further, a comparative analysis of key management schemes is to be performed for identifying an efficient key management scheme for hierarchical MANETs. In key management methods, public and private group key management schemes are integrated at local level (subgroup) and global level (network). These key management schemes uses various topologies for minimizing communicational and computational costs. After implementing an efficient key management scheme, outliers in network are identified using packet analysis at key generation, key distribution, message transmission and key re-generation phases. It is observed that Teo and Tan key management approach with shamir’s threshold key distribution mechanism is an efficient approach key management scheme for group authentication and hierarchical key management. Further, a minimum improvement of 9.7% and 0.91%, and maximum improvements of 25.3% and 87.7% are observed for Packet Delivery Rate (APDR) and Average Throughput (AT) respectively in a network of 1000 nodes. The proposed method requires four sequential analysis of outlier detection schemes at different layers of MANET protocol stack because single scheme per layer is not efficient in identifying outliers in proposed network. The proposed key management method is useful for MANETs in group authentication and implementation of lightweight cryptographic primitives with secure key. Further, outlier detection mechanism can be extended for identifying various active and passive attacks.

P2P networks have characteristics of decentralization, autonomy, and dynamicity. The security problems caused by these characteristics have seriously affected further development of P2P networks. The authors did research on CL-PKC key management schemes. (1) They propose a certificateless-based key distribution scheme with multiple trusted centers that fits the characteristics of P2P networks, and analyzed its security. (2) They also propose an improved interactive key agreement protocol across multiple domains, and then compare it with some existing key agreement protocol from aspects of security and computational efficiency. (3) The authors have implemented the proposed key management schemes, then verified their correctness and tested their computational efficiency. Combined with master key share management and key management of nodes, this system constructed a complete certificateless-based key management model, which is an exploration to solve security problems in P2P networks.

Key Management Scheme

Heterogeneous cluster-based wireless sensor networks (WSN) attracted increasing attention recently. Obviously, the clustering makes the entire networks hierarchical; thus, several kinds of keys are required for hierarchical network topology. However, most existing key management schemes for it place more emphasis on pairwise key management schemes or key predistribution schemes and neglect the property of hierarchy. In this paper, we propose a complete hierarchical key management scheme which only utilizes symmetric cryptographic algorithms and low cost operations for heterogeneous cluster-based WSN. Our scheme considers four kinds of keys, which are an individual key, a cluster key, a master key, and pairwise keys, for each sensor node. Finally, the analysis and experiments demonstrate that the proposed scheme is secure and efficient; thus, it is suitable for heterogeneous cluster-based WSN.
