Challenges

ELIB (Mohanty et al. 2020)

An efficient lightweight,

integrated Blockchain

(ELIB) model for IoT

security and privacy

The ELIB model proposes an overlay network

where IoT devices can securely communicate. It

proposes various aspects such as consensus

algorithms, DTM (Distributed Throughput

Management) and certificate-less cryptography to

address the challenges.

The proposed solution can be further

expanded to other areas beyond the smart

home to examine better the capabilities

being offered, and the same can be

improved.

IDS (Kim et al. 2018)

Intrusion detection and

mitigation system using

blockchain analysis for

Bitcoin exchange

The solution utilizes the decentralized nature of

blockchain for the intrusion detection system

(IDS). The proposed solution works with a

traditional IDS, and the traditional intrusion

prevention system (IPS) is a fail-safe option. This

solution addresses the intrusions explicitly in

Bitcoin exchanges.

The solution is currently limited to Bitcoin

blockchain, and further research needs to

be carried out to extend it to other

blockchain-based cryptocurrencies. The

proposed solution does not do away with

traditional IPS and uses it as a fall-back

and fail-safe.
