(Repeat in @tech) We have previously talked about having the ability to turn off the external entropy source. I would suggest that the ability to turn the entropy source on or off is given to the FPGA. (Which of course could expose the control via the core API). If the control is done by the CPU or Tamper-MCU, then we could easily end up reseeding the CPRNG using only the ring oscillator based entropy provider. Having support for turning the entropy source off ana on adds quite a lot of complexity in terms of warm up times and startup testing vs starvation of RNG output and race problems. When I look in Rev02, sheet 03 I assumed there would be a control signal for this function, but I don't see it. Has it not been included? - -- Med vänlig hälsning, Yours Joachim Strömbergson - Alltid i harmonisk svängning. ======================================================================== Joachim Strömbergson Secworks AB [email protected] ======================================================================== -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBCAAGBQJWpjoFAAoJEF3cfFQkIuyNLqgP/1dyg1RmLPm8/+J1CWitkOCu EJ9rJf9x2ZJyh91oDR14rGXpiftM79LLpN/r+FLVgkD45kCdTCdocwdcG3IAnWWu AGvUi48HQ68xEcyNoMU8l58Cnohqyn8YpSo4kqjpjx2Z6qVI6EsmQeion53J/UDm 6HMB9WeeW5mM7fRGzoHat8/PUXr1ohRiKL6nahggjTaH3WY0kidcq+6y6prhaw8H B/iJpgs/XfnV4cmaXX3ke8kpJk81SgvTBzFtl2j5omu4q94aLWrJOe502jYc8rrf JcQcLepJWS01hz03Zmxh0Y0iJQn2TpyEfCe3pKmX+D7K4zfRcagIcr9R69PHLOL9 biSFTFcX22qBDezm86CrTVHVLvsHILGTeWmRv4HOW8bKSjhNDc16rb/3oOAokIoZ TmjVb+po9Xn3d1qGilxUCK0A3j/1tp+G8tno9+EEp3/M+LX2Ui4Ys0p5eVESP+lo b2uVILoGNirja5HDV8y+6dMSbY7uPArjil3We009jB4gsHrkIdT5usClwrpo4gil L1YjtGwGzRmRfSskmaPkEdI+uAAGPos8zigd4sfHPwBjabkqqnjBBrbOcZcca3rE YfWENNJjPWK1/C7dgiiuGDa3L+WzKSWfh7dglbeJqZctb2eBd+iAALkj5vjGRcHg Z5QWnFjPhE3w5YGhOdVM =r9R4 -----END PGP SIGNATURE----- _______________________________________________ Tech mailing list [email protected] https://lists.cryptech.is/listinfo/tech
