Take Aways• Understand the business

Mission 1

• Feature: Secure message transport– As a network provider I want to ensure that messages can be sent securely

• Example:– Secure message transport– Given that a user wants to transport a message to a specific destination, I want to

ensure that only the sender and the receiver can read the message• Example:

– Detect security breach– Given that a user wants to transport a message to a specific destination, I want to

ensure that I can detect if someone other than the sender and the receiver tries to read the message

Mission 2

• Feature: Transport mechanism reuse– As a network provider I want to ensure that I can use my transport mechanism

multiple times • Example:

– Reuse transport mechanism– Given that a user wants to transport a message to a specific destination, I want to

ensure that the user can transport another message using the same mechanism

Mission 3

• Feature: Indirect transport– As a network provider I want to ensure that messages can be sent using an

arbitrary route• Example:

– Random message transport route– Given that a user wants to transport a message, I want to ensure that the message

route is random

Mission 4

• Feature: Messaging for distance– As a network provider I want to ensure that messages can be sent from one end of

a room to another• Example:

– Message distance transport– Given that a user wants to transport a message across a room, I want to ensure

that the message arrives intact
