Ideally secure systems must, be provable secure, so they are alldefined by mathematical models. Most of current systems are basedon the Bell and LaPadula Model (BLM), however, many usages are notlogically sound. In this paper, a new paradigm is proposed toreinterpret the BLM. BLM is treated as axioms to define themultilevel security, in the same spirit as Hilbert axioms to theEuc1idean geometry. Absolutely no violations are tolerated. So manyusual trusted subjects are no longer admissible in this new BLM.Three layer architecture is proposed to accommodate suchrequirements.
