提高NFT引用数据存储的机密性
Improving Confidentiality for NFT Referenced Data Stores
摘要：
不可替换令牌（NFT）通常使用URL或另一个唯一标识符来引用数据存储位置。至少，NFT有望保证对代币化资产的所有权和控制权。但是，存储在第三方数据存储中的信息可能会被复制和窃取。我们提出了一种解决方案，通过将加密内容存储在数据存储上并提供额外的安全性来防止黑客攻击和零日漏洞利用，从而将控制权交还给信息所有者。在密钥更新期间，我们数据存储中的内容永远不会解密或返回给其所有者进行解密。此外，在我们的协议中的密钥大小不会随着每次密钥更新而增加。这样，我们减少了同步步骤，并保持了有限的密钥大小。
英文摘要：
A non-fungible token (NFT) references a data store location, typically, using a URL or another unique identifier. At the minimum, a NFT is expected to guarantee ownership and control over the tokenised asset. However, information stored on a third party data store may be copied and stolen. We propose a solution to give control back to the information owner by storing encrypted content on the data store and providing additional security against hacks and zero day exploits. The content on our data store is never decrypted or returned to its owner for decryption during rekeying. Also, the key size in our protocol does not increase with each rekeying. With this, we reduce the synchronisation steps and maintain a bounded key size.
