hlf-time-oracle

hlf-time-oracle hlf-time-oracle 是一个为区块链 Hyperledger Fabric 提供的链码，用于向其他链码提供精确时间。hlf-time-oracle 基于 ntp 包 和 nts 包。从而解决了区块链客户端可能通过 交易时间操纵（CVE-2024-45244）带来的安全问题。该链码提供了 GetTimeNtp 和 GetTimeNts 函数。调用这些函数会触发对 NTP（网络时间协议）和 NTS（网络时间安全）服务器的请求。从这些服务器获取的时间可用于验证客户端定义的事务时间的正确性。区块链链码开发者可以使用...

HLF_TxTime_spoofing

HLFTxTimespoofing HLFTxTimespoofing —— 一个概念验证项目，涵盖了 Hyperledger Fabric 区块链中交易时间操纵的问题（使用 GetTxTimestamp 或 GetHistoryForKey）。已在 v2.5.5 和 v3.0.0-beta 版本上测试。 项目由以下几部分组成： 1. timeinsecure - 使用 GetTxTimestamp 计算存款利息的不安全链码变体 2. timesecurentp - 一个从 NTP（网络时间协议）服务器获取时间以防范攻击者在计算存款利息时进行时间欺骗的链码 3. timesecurent...
