Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “The first check (signatureVerificationResult == 0x3CA5965A) determines whether signatureVerificationResult has the correct and expected value.”

A block of code is set as follows:

if (signatureVerificationResult == 0x3CA5965A)
{
    // Hamming distance check passed, now perform a second check using
    // the inverse of the variable
    if (~signatureVerificationResult != 0xC35A69A5)
    {
        Log_fault(error_type);
    }
    else
    {
        Allow_application_to_run(); // Attacker wants to get here
                                    // through glitching
    }
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “SAE J2497 is a communication protocol used in commercial trucks to allow the exchange of data between the tractor and the trailer, such as the ABS trailer status lamp.”
