20110055592 | METHOD OF OBFUSCATING A CODE - A method of obfuscating a code is provided, wherein the method comprises performing a first level obfuscating technique on a code to generate a first obfuscated code, and performing a second level obfuscating technique on the first obfuscated code. In particular, the code may be a software code or a software module. Furthermore, the first level obfuscating technique and the second obfuscating may be different. In particular, the second level obfuscating technique may perform a deobfuscation. | 03-03-2011 |
20120131340 | Enrollment of Physically Unclonable Functions - Aspects of the present disclosure are directed toward a method that includes a physically-unclonable function (PUF) device that receives a communication that includes a first challenge value, a second challenge value and a remote message authenticity value. The method includes the generation of additional challenge-response pairs in a secure manner. The additional challenge-response pairs are securely communicated between the PUF device and an authenticating server or other device for subsequent use in authentication. | 05-24-2012 |
