I decided to see what other items come up with such a term. In doing so, I found someone who eats, sleeps, and breathes code obfuscation the same way I do de-obfuscation and reverse engineering.<\/p>\n<blockquote><p>\nAnd if &#8220;deobfuscating java&#8221; brought you here, <a href=\"\/pre\/re-retroguard.html\">this page on Retroguard deobfuscation<\/a> is the reason.\n<\/p><\/blockquote>\n<p>Meet <a href=\"http:\/\/www.tyma.com\/\">Paul Tyma<\/a>, Ph.D. I became aware of him through this <a href=\"http:\/\/www.pbs.org\/cringely\/\">I, Cringely<\/a> column entitled <a href=\"http:\/\/www.pbs.org\/cringely\/pulpit\/pulpit20040219.html\">&#8220;Misinterpretation&#8221;<\/a>. Tyma and his company <a href=\"http:\/\/www.preemptive.com\/\">PreEmptive Solutions<\/a> have developed code obfuscators for both the Java and .NET languages. The article notes that one technique under development (possibly already deployed?) is called &#8220;Program State Code Protection&#8221;. From what I can discern, it almost sounds like self-modifying code for Java. I would be interested to see it in action.<\/p>\n<p>Further, the company has 2 patents assigned to it:<\/p>\n<ul>\n<li>6,102,966: Method for renaming identifiers of a computer program<\/li>\n<li>5,903,761: Method of reducing the number of instructions in a program code sequence<\/li>\n<\/ul>\n<p>Tyma also has an article in a Java publication entitled <a href=\"http:\/\/today.java.net\/pub\/a\/today\/2004\/10\/22\/obfuscation.html\">&#8220;The New Obfuscation&#8221;<\/a>.
