This indicates socket U14 held a cryptographic S-box lookup table for decrypting the Stardust keystream. Without U14, the board can track the 14.2 Hz carrier, but cannot descramble the binary payload of Nodes 11 through 14. Does anyone have a 27C256 EPROM marked 'MH-U14' or 'ORION-CRYPTO'? -- Matthias Kim *PLONK* filter active for trolls. 486DX4/100 (FreeBSD 2.0.5) - NetBSD 1.0 From rhernandez@cmu.edu Sat Jul 27 03:50:30 1996 Path: ashpoly!cascade!transat!sunet!nordrelay!cmu!rhernandez From: rhernandez@cmu.edu (Raj Hernández) Newsgroups: comp.sys.m68k Subject: Re: [FLAME] Disassembling socket U14 firmware on the TWIN-68 board Message-ID: <1996Jul27.035030.9021@cmu.edu> Date: Sat, 27 Jul 1996 03:50:30 GMT References: <1996Jul25.194130.5940@uu.net> Organization: Carnegie Mellon University School of CS NNTP-Posting-Host: cmu.edu X-Newsreader: NewsWatcher 2.0b24 Lines: 9 In article <1996Jul25.194130.5940@uu.net>, mkim@uu.net (Matthias Kim) writes: > Hardware disassembly report for Motorola hardware hackers.

Using an S-box in a 27256 EPROM for single-cycle hardware substitution was standard military cipher practice in 1984. Unsubscribe me from this list!
