+<p>This document introduces an extension to the <span><em>PSA Cryptography API</em> <a class="reference internal" href="about.html#citation-psa-crypt"><span class="cite">[PSA-CRYPT]</span></a></span> specification, to provide support for <a class="reference internal" href="about.html#term-password-authenticated-key-exchange"><span class="term">Password-authenticated key exchange</span></a> (PAKE) algorithms, and specifically for the J-PAKE algorithm.</p>
+<p>When the proposed extension is sufficiently stable to be classed as Final, it will be integrated into a future version of <a class="reference internal" href="about.html#citation-psa-crypt"><span class="cite psa_c psa_c-cite">[PSA-CRYPT]</span></a>.</p>
+<p>This specification must be read and implemented in conjunction with <a class="reference internal" href="about.html#citation-psa-crypt"><span class="cite psa_c psa_c-cite">[PSA-CRYPT]</span></a>. All of the conventions, design considerations, and implementation considerations that are described in <a class="reference internal" href="about.html#citation-psa-crypt"><span class="cite psa_c psa_c-cite">[PSA-CRYPT]</span></a> apply to this specification.</p>

+<h2>1.1. Objectives for the PAKE Extension</h2>
+<div class="section" id="scheme-review">
+<h3>1.1.1. Scheme review</h3>
+<p>There are a number of PAKE protocols in circulation, but none of them are used widely in practice, and they are very different in scope and mechanics.
+The API proposed for the PSA Cryptography API focuses on schemes that are most likely to be needed by users. A number of factors are used to identify important PAKE algorithms.</p>
+<div class="section" id="wide-deployment">
+<h4>Wide deployment</h4>
+<p>Considering PAKE schemes with already wide deployment allows users with existing applications to migrate to PSA.
+Currently there is only one scheme with non-negligible success in the industry: Secure Remote Password (SRP).</p>
+</div>
+<div class="section" id="requests">
+<h4>Requests</h4>
+<p>Some PAKE schemes have been requested by the community and need to be supported.
+Currently, these are SPAKE2+ and J-PAKE (in particular the Elliptic Curve based variant, sometimes known as ECJPAKE)</p>
+</div>
+<div class="section" id="standardization">
+<h4>Standardization</h4>
+<p>There are PAKE schemes that are being standardized and will be recommended for use in future protocols.
+To ensure that the API is future proof, we need to consider these.
+The CFRG recommends CPace and OPAQUE for use in IETF protocols.
+These are also recommended for use in TLS and IKE in the future.</p>
+</div>
+<div class="section" id="applications">
+<h4>Applications</h4>
+<p>Some of these schemes are used in popular protocols. This information confirms the choices already made and can help to extend the list in future:</p>

+<p>A PAKE algorithm uses a specific cryptographic primitive for key establishment, specified using a <a class="reference internal" href="#pake-primitive"><span class="std std-ref">PAKE primitive</span></a>. PAKE algorithms also require a cryptographic hash algorithm, which is agreed between the participants.</p>
+<p>The <a class="reference internal" href="#c.psa_pake_cipher_suite_t" title="psa_pake_cipher_suite_t"><code class="xref any c c-type docutils literal"><span class="pre">psa_pake_cipher_suite_t</span></code></a> object is used to fully specify a PAKE operation, combining the PAKE algorithm, the PAKE primitive, the hash or any other algorithm that parametrises the PAKE in question.</p>
+<p>A PAKE cipher suite is required when setting up a PAKE operation in <a class="reference internal" href="#c.psa_pake_setup" title="psa_pake_setup"><code class="xref any c c-func docutils literal"><span class="pre">psa_pake_setup()</span></code></a>.</p>

+<p>This is the object that represents the cipher suite used for a PAKE algorithm. The PAKE cipher suite specifies the PAKE algorithm, and the options selected for that algorithm. The cipher suite includes the following attributes:</p>
+<ul class="simple">
+<li>The PAKE algorithm itself.</li>
+<li>The PAKE primitive, which identifies the prime order group used for the key exchange operation. See <a class="reference internal" href="#pake-primitive"><span class="secref">PAKE primitives</span></a>.</li>
+<li>The hash algorithm to use in the operation.</li>

+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p>Implementations are recommended to define the cipher-suite object as a simple data structure, with fields corresponding to the individual cipher suite attributes. In such an implementation, each function <code class="docutils literal"><span class="pre">psa_pake_cs_set_xxx()</span></code> sets a field and the corresponding function <code class="docutils literal"><span class="pre">psa_pake_cs_get_xxx()</span></code> retrieves the value of the field.</p>
+<p class="last">An implementations can report attribute values that are equivalent to the original one, but have a different encoding. For example, an implementation can use a more compact representation for attributes where many bit-patterns are invalid or not supported, and store all values that it does not support as a special marker value. In such an implementation, after setting an invalid value, the corresponding get function returns an invalid value which might not be the one that was originally stored.</p>

+<p>At this step in the PAKE operation there is a cryptographic guarantee that only an authenticated participant who used the same password is able to compute the key.
+But there is no guarantee that the peer is the participant it claims to be, and was able to compute the same key.</p>
+<p>In this situation, the authentication is only implicit.
+Since the peer is not authenticated, no action should be taken that assumes that the peer is who it claims to be
+For example, do not access restricted files on the peer’s behalf until an explicit authentication has succeeded.</p>
+<p>This function can be called after the key exchange phase of the operation has completed.
+It injects the shared secret output of the PAKE into the provided key derivation operation.
+The input step <code class="xref any docutils literal"><span class="pre">PSA_KEY_DERIVATION_INPUT_SECRET</span></code> is used to input the shared key material into the key derivation operation.</p>
+<p>The exact sequence of calls to perform a password-authenticated key exchange depends on the algorithm in use.

The driver interface is being tried out in Mbed TLS. Arm expects to make it an official PSA specification once it has been sufficiently validated.</p>
