Elliptic Curve Cryptography (ECC) is one of the public key cryptosystems that works based on the algebraic models in the form of elliptic curves. Usually, in ECC to implement the encryption, the encoding of data must be carried out on the elliptic curve, which seems to be a preprocessing step. Similarly, after the decryption a post processing step must be conducted for mapping or decoding the corresponding data to the exact point on the elliptic curves. The Memory Mapping (MM) and Koblitz Encoding (KE) are the commonly used encoding models. But both encoding models have drawbacks as the MM needs more memory for processing and the KE needs more computational resources. To overcome these issues the proposed enhanced Koblitz encoding technique is used with the ECC for enhancing the security. The proposed model was compared to the existing model and found to be more efficient in terms of security. The proposed model ensure confidentiality with the encryption technique, Integrity by using the Hashing method, and authenticity and non-repudiationwith the utilization of digital signature.

“…For illustrative purposes, suppose Alice has 1 Bitcoin token in her Bitcoin wallet (a digital address) and wants to transfer it to Ben’s Bitcoin wallet. Both Bitcoin wallets have their own unique private and public keys, where their respective public and private keys are mathematically related on an Elliptic Curve (Easttom, 2020). To transfer the Bitcoin token, Alice would cryptographically sign the transaction and the public key of Ben’s Bitcoin wallet with Alice’s wallet’s private key, which creates a hash, and post it to the public ledger on the Bitcoin network.…”

Purpose The purpose of this paper is to examine the currently known techniques to tackle money laundering in Bitcoin mixers, and examine what gaps exist that would allow a criminal to get away with laundering Bitcoin obtained through illicit activities. Design/methodology/approach This paper first establishes the relevant properties of Bitcoin, how transactions occur over the Bitcoin network and then introduces the Bitcoin transaction graph as an important data structure for any analysis of Bitcoin transactions. Next, the paper outlines how Bitcoin mixing works, along with the relevant properties of mixers that would be relevant for money laundering. The paper then assesses the known methods for identifying mixed transactions within the Bitcoin network, followed by an assessment on identifying money laundering activities on known mixed transactions. Findings This paper argues that there remains a gap for criminals to launder money through Bitcoin mixing services as known methods would unlikely be able to trace a tainted transaction that goes through a decentralized mixer that uses off-chain communication techniques to coordinate the mixing and charges randomized mixing fees. Research limitations/implications The study of known methods is restricted to literature published in the public domain. There are private organizations that are tackling similar problems, but their methods are not published and therefore cannot be included in this paper. Originality/value To best of the author’s knowledge, this is the first paper that performs a contemporaneous review on anti-money laundering in the context of Bitcoin mixing. This paper could assist regulators and policymakers in their understanding of Bitcoin mixers and provide guidance on where they should focus their resources to address the money laundering problem of Bitcoin mixing.
