ABSTRACT
<p><b>Abstract</b>—A widely used bus-encryption microprocessor is vulnerable to a new practical attack. This type of processor decrypts on-the-fly while fetching code and data, which are stored in RAM only in encrypted form. The attack allows easy, unauthorized access to the decrypted memory content.</p>
INDEX TERMS
