Abstract: In the digital economy, the demand for financial data sharing among enterprises is growing rapidly. Traditional financial sharing models face prominent issues, including data security risks, insufficient efficiency and transparency. To enable the encrypted storage and hierarchical access of sensitive financial data, this study proposes a blockchain-based scheme for secure sharing and encrypted computation of enterprise financial information. The blockchain component incorporates credibility evaluation, process optimization, and cross-organizational collaboration models. Its layered architecture optimizes sharing efficiency and supports applications in supply chain finance, among other scenarios. The encryption component is based on the Number Theory Research Unit (NTRU) encryption algorithm, which utilizes polynomial rings, homomorphic encoding, and secure two-party protocols to ensure data privacy and operational integrity. The synergy between these two components provides digital support for the integration of business and finance as well as ecological collaboration. Experimental results showed that the proposed method achieved a stable transaction throughput of 4,500 TPS and reduced audit time by 79.8%. In practical application testing, the proposed method achieved stable financial error and audit variance rates of 0.3% and 0.2%, respectively, with storage costs that stabilized at approximately 0.5 yuan/GB/month. The blockchain-based platform for enterprise financial information sharing and encrypted computation proposed in this study demonstrates high data quality, compliance, and security. This platform effectively solves the problems of low security, inefficiency, and non-compliance.
Keywords: Enterprise financial information sharing platform, blockchain technology, number theory research unit encrypt, cross-organizational collaboration model, homomorphic encoding.
