+
+<p class=MsoBodyText>The internal Forward Lock file format is used for encrypting
+inherently unencrypted OMA DRM version 1 Forward Lock and Combined Delivery
+files so they can be securely stored on externally accessible file system partitions
+such as memory stick.</p>
+
+<p class=MsoBodyText>Our general strategy is to convert such <i>OMA DRM Message</i>
+(‘.dm’) files to internal Forward Lock (‘.fl’) files as soon as they are
+downloaded or otherwise transferred to the phone, and not actually provide any
+decoders for ‘.dm’ files.</p>
+
+<h1><a name="_Toc276471423">2<span style='font:7.0pt "Times New Roman"'>
+</span>Overview</a></h1>
+
+<p class=MsoBodyText>The <i>Forward Lock Converter</i> converts OMA DRM Message
+files to the internal file format. The <i>Forward Lock Decoder</i> provides a
+POSIX-level API for transparent reading and seeking through such a converted
+file as if it were unencrypted. The API also includes functions for checking a
+fileÂ’s integrity and getting the MIME type of its embedded content.</p>
+
+<p class=MsoBodyText style='margin-bottom:24.0pt'>The converter and decoder are
+built into two separate libraries, which share common code for random number
+generation and key encryption in a third library. For test purposes there is
+also a unit test application. See Figure 1.</p>

+</span>Use Cases</a></h1>
+
+<p class=MsoBodyText>This section describes all the use cases for the converter
+and decoder. It shows the sequence of API calls that should be used to solve
+these use cases.</p>
+
+<h2><a name="_Toc276471425">3.1<span style='font:7.0pt "Times New Roman"'>
+</span>Converter</a></h2>
+
+<p class=MsoBodyText>Through the converter API, conversion can be performed in one
+of two ways:</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>1.<span
+style='font:7.0pt "Times New Roman"'> </span><i>Push-mode
+conversion</i> is when the client progressively feeds data to the converter as
+it arrives. This is appropriate when data arrives gradually in chunks, with
+idle time in between. Consequently, push mode is used for converting files
+being downloaded through HTTP. See section 3.1.1.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>2.<span
+style='font:7.0pt "Times New Roman"'> </span><i>Pull-mode
+conversion</i> is when the converter drives the process and consumes data from
+the client as it needs it. This is appropriate when the entire file to be
+converted is readily available. Hence, pull mode is used by the unit test application.
+See section 3.1.2.</p>
+
+<p class=MsoBodyText>Internally, pull-mode conversion is implemented in terms
+of the API for push-mode conversion.</p>
+
+<h3><a name="_Toc276471426"></a><a name="_Ref263085478">3.1.1<span
+style='font:7.0pt "Times New Roman"'> </span>Convert Data
+(Push-Mode Conversion)</a></h3>
+
+<p class=MsoBodyText>Push-mode conversion is performed as follows (see also Figure 2):</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>1.<span

+initializes the output parameter and returns a <i>session ID</i> to be used in
+subsequent calls to the API. The output parameter is a union of return values
+whose correct use at any given moment is determined by the API function last
+called.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>2.<span
+style='font:7.0pt "Times New Roman"'> </span><span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockConv_ConvertData</span>
+is called repeatedly until no more input data remains. Each call converts the
+maximum amount of data possible and writes it to the output buffer. The client then
+writes this data to file.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>3.<span
+style='font:7.0pt "Times New Roman"'> </span><span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockConv_CloseSession</span>
+cleans up the session and deallocates the output buffer. If all has gone well, a
+two-part cryptographic signature of the output file is calculated. The client
+must go back and rewrite part of the file header with this updated signature
+information.</p>
+
+<p class=MsoBodyText>Every time a file is being converted, the converter calls <span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockGlue_GetRandomNumber</span>
+to generate a new, unique session key. No two converted files look alike, even
+if the original files are the same.</p>
+
+<p class=MsoBodyText><b>Note:</b> The random bytes cannot come from any bare-minimum
+implementation of the C-library <span style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>rand</span>
+function—they must be cryptographically secure. Otherwise, security will be
+compromised.</p>
+
+<p class=MsoBodyText>The session key is encrypted and stored within the
+converted file. Key encryption is performed using <span style='font-size:10.0pt;
+font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockGlue_GetEncryptedKeyLength</span> and <span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockGlue_EncryptKey</span>.
+These two functions, together with the corresponding decryption function (<span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockGlue_DecryptKey</span>),
+are the integration points where an OEM manufacturer may implement their own
+key-encryption scheme.</p>
+
+<p class=MsoBodyText><b>Note:</b> The key-encryption key must be unique to each
+device; this is what makes the files forward lock–protected. Ideally, it should
+be derived from secret hardware parameters, but at the very least it should be
+persistent from one master reset to the next.</p>

+the file system, without being obfuscated in any way (doing so would be futile
+since the source code is openly available). This key must be kept secret from
+the user, and shouldnÂ’t be possible to extract through backup-and-restore

+<p class=MsoBodyText>The encryption key is the output from encrypting the
+16-byte all-zero input block {0, 0, Â…, 0} using 128-bit AES with the random session
+key as the key. The signing key is the output from encrypting the 16-byte input
+block {1, 0, Â…, 0} the same way. The keys so derived will be cryptographically
+independent from each other.</p>
+
+<p class=MsoBodyText>The session key is encrypted using a hardware-dependent
+key-encryption key unique to each device. The encrypted session key is stored
+inside the file, and its first sixteen bytes are also used as the <i>nonce</i>
+for the CTR-mode encryption of the content data.</p>

+<h2><a name="_Toc276471434">4.2<span style='font:7.0pt "Times New Roman"'>
+</span>Calculation of the Counters</a></h2>
+
+<p class=MsoBodyText>Using CTR (“counter”) mode, a block cipher such as AES can
+be turned into a stream cipher. The process of encryption and decryption is
+well defined in [1], except for the specifics of the calculation of the
+counters. For the internal Forward Lock file format, the counters are
+calculated as follows:</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>1.<span
+style='font:7.0pt "Times New Roman"'> </span>The
+nonce is interpreted as a 128-bit unsigned integer in little-endian format.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>2.<span
+style='font:7.0pt "Times New Roman"'> </span>The
+zero-based block sequence number (also a little-endian unsigned integer) is
+added modulo 2<sup>128</sup> to the nonce to produce the counter for a given
+block.</p>
+
+<h1><a name="_Toc276471435">5<span style='font:7.0pt "Times New Roman"'>
+</span>Unit Test Cases</a></h1>
+
+<p class=MsoBodyText>Unit test cases for the converter and decoder come in two
+varieties:</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>1.<span
+style='font:7.0pt "Times New Roman"'> </span><i>Black-box</i>
+test cases aim to verify that you get sensible results from malformed or
+“tricky” input data.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>2.<span
+style='font:7.0pt "Times New Roman"'> </span><i>White-box</i>
+test cases aim to maximize code coverage using knowledge of code internals.</p>
+
+<p class=MsoBodyText>The black-box test cases are dependent on a specifically
+designed set of input files found in the <span style='font-size:10.0pt;
+font-family:"Lucida Console","DejaVu Sans Mono"'>forward-lock/internal-format/test/res</span>
+directory in the repository. For ‘tests’ variants of the software, these input
+files will be automatically installed in the file system image during build.</p>
+
+<p class=MsoBodyText>Run the test cases from the ADB shell command line as
+follows:</p>
+
+<p class=MsoNormal style='margin-top:0cm;margin-right:0cm;margin-bottom:6.0pt;
+margin-left:21.55pt'><span style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>#
+gtest_fwdlock</span></p>
+
+<p class=MsoBodyText>If all black-box but no white-box test cases fail, the
+input files probably canÂ’t be found in the working directory.</p>
