摘要

给出了热噪声和混沌真随机数发生器的实现。它们嵌入在大型商用SoC中,用于加密应用程序(SSL和密钥生成)。它们的输出被组合起来以提高比特流的随机性。设计目标是尽量减少由电源和基板注入的数据相关噪声的影响。随机比特率为2Mbit/s,通过DIEHARD测试套件。在65nm CMOS工艺中,TRNG的面积为0.21mm2。

Dual True Random Number Generators for Cryptographic Applications Embedded on a 200 Million Device Dual CPU SoC
Implementations of a thermal noise and a chaotic True Random Number Generator (TRNG) are presented. They are embedded in a large commercial SoC and used for cryptographic applications (SSL and key generation). Their outputs are combined to improve the randomness of the bit stream. The design goal was to minimize the effect of data dependent noise injected by the supplies and substrate. The random bit rate is 2Mbit/s and passes the DIEHARD test suite. The area of the TRNG is 0.21mm2 in a 65nm CMOS process.
