TCOOF-Trust

Ensemble-based access control framework.

Define your security policy like this:

class SimpleScenario(val people: Seq[Person]) {

  class HelloWorld extends Ensemble {
    val greeter = oneOf(people)

    allow(greeter, "greet", people)
  }

  val policy = Policy.root(new HelloWorld)
}

Find the solution and query access rights:

val names = Seq("Roland", "Lilith", "Mordecai", "Brick")
val people = for (name <- names) yield new Person(name)
val scenario = new SimpleScenario(people)

val roland = people(0)
val lilith = people(1)
scenario.policy.resolve()
if (scenario.policy.allows(roland, "greet", lilith)) {
  println("Roland says: Hello, Lilith!")
}

Requirements

For generating graphs:

Graphing scripts should work with any Python later than 3.6, but the requirements are locked to 3.6. You might need to modify Pipfile.

Usage

To run the example program:

$ sbt run

To run the unit test suite:

$ sbt test

To run the measurement suite:

$ sbt "run scenario.MeasureAll"

Results will be saved in results/YYYY-MM-DD directory.

To generate graphs from measurements saved in results/final:

$ ./python/all.sh

Including in your project

Generate the JAR with:

$ sbt package

Then copy target/scala-2.12/tcoof-trust_2.12-1.0.jar into a lib/ subdirectory of your project.

Documentation

To generate the API documentation:

$ sbt doc

Documentation is saved to target/scala-2.12/api.

You can find the user guide and implementation notes in the thesis.

Development

Install IntelliJ IDEA with Scala plugin, and open this repository as a Scala project.
