This description of a roleplay to demonstrate security practices relate to a workshop being planned for [wiki:nyc_anarchist_book_fair_2008].

= Security demonstration =

For this demonstration we'll need a bunch of volunteers.  
  * 2 people on opposite sides of the room, mail provider X and mail provider Y.
  * 6 e-mailers: 
   * A@X.com
   * B@Y.com
   * C@X.com
   * D@Y.com
   * E@X.com
   * F@Y.com 
We can add more folks if we want more successfully sent messages.
  * 1 "You've got mail" person.

== Instructions/demonstrate the "mail sending" ==

I'm Jon@X.com.  I want to send a message to Jamie at Y.com.  So I write it, and I 
put Jamie's name on the top, and give my message to X.com.  They see that it's for
Y.com, and they pass it along to a number of other computers until it reaches the 
Y.com computers.  Next time Jamie decides to check his e-mail, he gets a copy from
Y.com. He can reply  and send it back, or forward it to someone else.

Since we're on a schedule, I'm going to ask that folks please follow the 
directions they're given and not decide to send e-mail via paper airplanes etc.

Normally, we don't see this process, so I'm going to ask person B-F to leave the 
room (or turn their backs).  The "You've got mail" person will tell you to come in 
when it's your turn to check your e-mail. 

People B-F leave the room.  Everyone's instructions have a note at the top asking them to please note share their instructions with others.

As each person sits down after sending their message, we ask them to please not 
say anything to the folks who check mail after them.

== Instructions for person A ==

Send a message with a short incriminating phrase of your choosing to person B.  If 
you can't think of one, use "I bought the dynamite."  When you're done, have a 
seat.

== Person B ==
You're expecting a message about an upcoming action.  Write a message telling your 
companer@ C when you'd like to plan a scouting run.  Plan it for nighttime some 
time in the next week.  Send it when you get an e-mail from person A.  After you 
send your e-mail, have a seat in the room.

{Police ask a router to hand them the message when it comes to them, take a 
picture of the message}

== Person C ==
You are planning an action.  You are expecting a message from person B about a 
scouting run in the next week.  

Write a message that says, "We'll do the action on the night of _ _ ."  When you 
get the message from person B, fill in a date a few days after the date of the 
scouting run and put it in the envelope, which represents encryption.  Put the 
address of person D and a subject on the outside of the envelope and send your 
e-mail.  After you send it, have a seat in the room.

{Police switch out an envelope, contents say, "The action is on.  Scouting run on 
Monday at noon."}

== Person D ==
You are planning an action.  You are expecting a message from person C about when 
the action should take place.

Forward that information to person E.  Put a note at the top like, "FYI, here's 
the info." Make sure to encrypt the message by putting it in an envelope.  Put the 
address of person E and a subject on the outside of the envelope  Also, sign the 
envelope with your name across the flap so they know the message came from you.  After you send the message, have a seat in the room.

{Police switch out the envelope for an envelope that they've signed}.

== Person E ==
You are planning an action.  Person D will forward the info on the action to you.  You should forward it to person F.

Make sure to encrypt the message by putting it in an envelope.  Put the 
address of person F and a subject on the outside of the envelope  Also, sign the 
envelope with your name across the flap so they know the message came from you.  After you send the message, have a seat in the room.

Just before you enter the room, please give these directions to person F.

== Person F (Could also be person A) ==

''(directions say,"Don't open this until instructed", which is when person D goes to check e-mail)''

As the last person, you won't be sending e-mail, just receiving.  

However, just before person E enters the room to check e-mail, have an in-person meeting with person E.  Ask them to write their signature for you, and also to leave their directions with you.
