Abstract

To what extent should one trust a statement that a program is free of Trojan horses? Perhaps it is more important to trust the people who wrote the software.

        Ken Thompson's 1983 Turing Award lecture is a fascinating glimpse at a current sociological phenomenon :V unauthorized access to computer systems. The first part of the lecture deals with a hacker's delight :V in C, of course. The second part extends the idea to illustrate how a compiler in this case, the C compiler can be made completely portable. The final extension, in the third part of the lecture, deals with untraceable insertions of Trojan Horses into program translators. The moral is unsettling, as well as obvious: If you didn't write it, you can't trust it.:L
