Certificateless aggregate signature-based carbon quota trading scheme

Carbon quota trading encourages enterprises to reduce carbon emissions by limiting their carbon emissions. However, carbon quota trading has some security problems, such as forgery, counterfeiting or tampering. Based on certificateless aggregate signature and smart contract technology, a secure carbon quota trading scheme is proposed. The use of certificateless aggregated signature technology ensures the integrity of carbon quota transactions, prevents transactions from being tampered with or forged, and avoids complex key management issues. The smart contract on the blockchain aggregates multiple single signatures to ensure the fairness of carbon quota trading. The analysis results show that the proposed scheme can protect the interests of enterprises of both sides of carbon quota trading and has higher computing and communication performance.
