چکیده

The emergence of Intelligent Connected Vehicles (ICVs) shows great potential for future intelligent traffic systems, enhancing both safety and road efficiency. However, the ICVs relying on data driven perception driving models face many challenges, such as lack comprehensive knowledge to deal with complicated context. In this paper, we investigate cooperative sharing ICVs. We propose a secure efficient blockchain based framework, wherein distributed learning scheme is utilized enhance efficiency directed acyclic graph (DAG) system designed guarantee security shared models. To cater time-intense demand highly dynamic vehicular networks, lightweight DAG reduce operation latency in terms fast consensus authentication. Moreover, further model accuracy well minimizing bandwidth consumption, an adaptive asynchronous (ADL) proposed uploading downloading. Experiment results show that framework secure, which reduces chosen confirmation delay resisting malicious attacks. addition, ADL enhances related performance compared several existing algorithms.

Enabling secure and resource-efficient blockchain networks with VOLT

We consider the problem of creating secure and resourceefficient blockchain networks i.e., enable a group of mutually distrusting participants to efficiently share state and then agree on an append-only history of valid operations on that shared state. This paper proposes a new approach to build such blockchain networks. Our key observation is that an append-only, tamper-resistant ledger (when ...

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...
