树奇偶校验机密钥更新体系结构
Tree Parity Machine Rekeying Architectures
摘要：
在嵌入式系统中，保护硬件组件之间的通信的必要性对于数据的保密性，特别是其商业用途变得越来越重要。我们建议一个低成本（即小逻辑面积）的解决方案，灵活的安全级别和短的密钥寿命。其基础是一种使用树奇偶校验机同步的对称密钥交换方法。快速连续的密钥生成使密钥交换在几毫秒内，给定的现实通信信道具有有限的带宽。为了演示，我们评估的标准单元ASIC设计实现的IP核在0.18微米CMOS技术的特点。
英文摘要：
The necessity to secure the communication between hardware components in embedded systems becomes increasingly important with regard to the secrecy of data and particularly its commercial use. We suggest a low-cost (i.e. small logic-area) solution for flexible security levels and short key lifetimes. The basis is an approach for symmetric key exchange using the synchronisation of Tree Parity Machines. Fast successive key generation enables a key exchange within a few milliseconds, given realistic communication channels with a limited bandwidth. For demonstration we evaluate characteristics of a standard-cell ASIC design realisation as IP-core in 0.18-micrometer CMOS-technology.
