Providing Root of Trust for ARM TrustZone using On-Chip SRAM
2014
Proceedings of the 4th International Workshop on Trustworthy Embedded Devices - TrustED '14
Preserved Fulltext
We first implement a building block which provides the foundations for the root of trust: secure key storage and truly random source. ...
In one word, we leverage the on-chip SRAM, commonly available on mobile devices, to achieve a low-cost, secure, and efficient design of the root of trust. ...
ACKNOWLEDGMENTS We thank Yevgeniy Dodis, Sylvain Ruhault for their suggestions on building our secure RNG. ...
