CryptoVault - A Secure Hardware Wallet for Decentralized Key Management

The intelligentization and connectedness of vehicles make vehicle cybersecurity an important research topic. In-vehicle key management is a critical function in vehicle cybersecurity countermeasures. After describing previous research on vehicle key management and the development trend of vehicle network architecture, a key management scheme for in-vehicle multi-layer electronic control units (ECUs) is proposed. The scheme is based on authenticated key exchange protocol 2 (AKEP2) and on-the-air (OTA) technology. Then, the key storage and trusted key usage based on secure hardware are analyzed and studied. Moreover, the AES Counter with CBC-MAC (AES-CCM) algorithm, which uses fewer keys, is introduced to in-vehicle secure communication. The simulation analysis for the proposed OTA-based key update protocol verifies the protocol’s security. The validity of the hardware-based trusted key usage environment and the feasibility of the AES-CCM algorithm for the CAN FD bus are proven with corresponding experiments.

Cluster Based Routing

Now days, wireless technology is one of the center of attention for users and researchers. Wireless network is a network having large number of sensor nodes and hence called as “Wireless Sensor Network (WSN)”. WSN monitors and senses the environment of targeted area. The sensor nodes in WSN transmit data to the base station depending on the application. These sensor nodes communicate with each other and routing is selected on the basis of routing protocols which are application specific. Based on network structure, routing protocols in WSN can be divided into two categories: flat routing, hierarchical or cluster based routing, location based routing. Out of these, hierarchical or cluster based routing is becoming an active branch of routing technology in WSN. To allow base station to receive unaltered or original data, routing protocol should be energy-efficient and secure. To fulfill this, Hierarchical or Cluster base routing protocol for WSN is the most energy-efficient among other routing protocols. Hence, in this paper, we present a survey on different hierarchical clustered routing techniques for WSN. We also present the key management schemes to provide security in WSN. Further we study and compare secure hierarchical routing protocols based on various criteria.
