FIPS 140-3 implementation in Go

Covers the following tests:

• Monobit
• Maximum series length
• Poker
• Series length

Each test takes 20000 bits as an input.

Work done

• keytest/monobit.go - Monobit test implementation.
• keytest/longestsequence.go - Maximum Series test implementation.
• keytest/poker.go - Poker test implementation.
• keytest/series.go - Series test implementation.
• keytest/keytest.go - contains a function to run all the tests.
• keytest/util.go - contains utility methods.
• example.go - a simple example of how to use the tests.

How to use

The following block of code can be found in example.go:

import (
	"fmt"
	"math/rand"

	"github.com/danielost/fips-140-3/keytest" // This import is needed to run the tests.
)

func foo() {
	// Most likely, you will have a real sequence of bits,
	// but fot the demostration we just generate a random binary value.
	length := 20000
	runeArray := make([]rune, length)
	for i := 0; i < length; i++ {
		runeArray[i] = rune('0' + rand.Intn(2))
	}
	binary := string(runeArray)

	// Run all the tests.
	result, err := keytest.RunAll(binary)
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println(result)
	}
}

If the sequence is considered random, the following output will be produced:
