Slug: AlphaSealedBags Title: Alpha Sealed Bags Author: Fredrik Thulin Date: 2016-12-16 14:09 Modified: 2016-12-16 14:12 Category: AlphaBoard ## Chain of custody At present, we can't make any statements at all about the integrity of the hardware before it reached us - assembled and ready. We test and program the Alphas using a dedicated computer, but not in a secure facility by any means. A concerned user is advised to reprogram the firmware with binaries built from source. To provide some assurance the devices have not been tampered with after they have been programmed we put them in sealed bags with individual serial numbers. As the model of bags might change over time, we will publish photos of the bags used here as well as PGP signed statements for what serial numbers can be expected. At this time, we do not keep records of which exact unit was sent to whom. This is a picture of the currently used bags: ![Alpha_tamper_bag_2016-12-16.png]({attach}/AlphaSealedBags/Alpha_tamper_bag_2016-12-16.png) ``` -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 At 2016-12-16, I put Cryptech Alpha units into sealed bags with the following serial numbers: 26 0 027 233 507 26 0 027 233 508 26 0 027 233 509 26 0 027 233 510 26 0 027 233 511 26 0 027 233 512 26 0 027 233 513 26 0 027 233 514 26 0 027 233 515 26 0 027 233 516 26 0 027 233 517 26 0 027 233 518 26 0 027 233 519 26 0 027 233 520 26 0 027 233 521 26 0 027 233 522 26 0 027 233 523 26 0 027 233 524 26 0 027 233 525 26 0 027 233 526 /Fredrik -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCgAGBQJYU/MVAAoJEBmMGv1QUVLd+2gH/jLZ7aUGlZ+Iwj6b746Hh6u1 2JAZ+2tk5tRooTwNb4A5P3ewRcbjA0jPJQQlpVqZcxdt0DDjS16AR0LEaH2rWL++ sj/OtBm5rqAmVcf1NNvzpC8f8WWgRYhx4nNhWKnEcTBQXT9NbFQhQY0WH3ebupnn 8PK0mX8PpfsjM/3vxtVVLmi+vBsxv0hBcdl+t4IPw/UbzozicF6jZpxRXxVujTE6 WLGXaCnySS4T1zgtpewfgVMOMouGScUw5n2yHRZJpissGUVJtuPrOEmNFvDz7LRD i00Rc4i2emsKTgKrkMIKyQWSqFIQ1nBUQ5B5ES1Q50432cppbyEW2rJJZjAuxgM= =s2D5 -----END PGP SIGNATURE----- ```
