摘要

默克尔哈希树用于保护数据集的完整性，防止各种攻击，包括重放。它们通常意味着巨大的存储和性能开销。本文介绍了几个建议(空心树，专用缓存)来减少这些开销。它们已经在SecBus中实现，SecBus是一种保护片上系统外部存储器的软件/硬件体系结构。

Performance optimizations of integrity checking based on Merkle trees

Merkle hash trees are used to protect the integrity of data sets, against all kinds of attacks, including replay. They usually imply a significant storage and performance overhead. This paper introduces several proposals (hollow trees, dedicated caches) to mitigate these overheads. They have been implemented in SecBus, a software / hardware architecture protecting the external memories of a System-on-Chip.
