+====== Authentication ======
+===== Principles =====
+Just a hash challenge (actually using [[https://en.wikipedia.org/wiki/Whirlpool_(cryptography)|Whirlpool]]) to resolve for masters in order to authenticate themselves, using a symmetric key, that needs to be sent to slaves.
+===== Key storage/auth methods =====
+Plugins on master side can be made to store and do the hash in an other way than plain raw key storage on the master's filesystem.
+==== Arduino/EEPROM method ====
+===== Permissions =====
+===== Key sending procedure =====
+Log on the slave side :\\
+{{:xifnet:ioslaves:screenshot_2016-08-29_a_02.40.24.png?direct|}}
+Log of the master which stores and sends its key to the slave :\\
+{{:xifnet:ioslaves:key-master-sending.png?direct|}}
+Log of the master which authorizes the first master to send the key, and chooses associated permissions :\\
+{{:xifnet:ioslaves:key-master-auth.png?direct|}}
+Logs of initial key sending (accepting the first key without being authenticated) :\\
