Parameter yang menentukan karakteristik kunci, termasuk mode penggunaan yang diotorisasi dan batasan kontrol akses. Parameter dibagi menjadi dua kategori, yaitu yang diterapkan oleh hardware aman, dan yang tidak. Untuk penerapan keymaster khusus software, array yang diterapkan harus NULL. Implementasi hardware harus menerapkan semuanya dalam array yang diterapkan.
