Abstract

An instructional management system (IMS) regularly manages student data with a centralized database, which may be prone to single points of failure and data tampering. Blockchain can effectively solve the above problems due to its decentralization and immutability. However, the immutability of blockchain restricts the edit of data in some cases (e.g., incorrect score records). In this paper, we propose an advanced decentralized instructional management framework based on redactable blockchain, wherein chain nodes possess the capability to autonomously revise their initiated transactions with regular chameleon hash functions. Concurrently, system users can anonymously report discrepancies or erroneous entries within the blockchain. When such reports are validated and malicious activities are confirmed, the review team can undertake decentralized modifications to rectify the malicious content with our proposed scheme. In addition, we conduct a security analysis of the scheme, evaluating its correctness, collision resistance, and claimability. Finally, experimental results demonstrate that the scheme is practical.

可读区块链，具有匿名和多权限，用于教学管理

教学管理系统（IMS）经常使用集中式数据库管理学生数据，这可能容易出现单点故障和数据篡改。区块链由于其去中心化和不变性，可以有效地解决上述问题。然而，区块链的不变性在某些情况下限制了数据的编辑（例如，错误的分数记录）。在本文中，我们提出了一种基于可读区块链的高级分散教学管理框架，其中链节点具有使用常规变色龙哈希函数自主修改其初始事务的能力。同时，系统用户可以匿名报告区块链中的不一致或错误条目。当这些报告被验证并且恶意活动被确认时，审查小组可以进行分散的修改，用我们提出的方案纠正恶意内容。此外，我们对该方案进行了安全性分析，评估了其正确性、抗碰撞性和可索赔性。最后，实验结果证明了该方案的实用性。
