This paper describes a new mandatory security model that better combines secrecy and commercial data integrity requirements than previous models based on Bell and LaPadula and Biba. The new model solves many of the previously perceived drawbacks and limitations of the Biba model, and makes use of a modified-Biba lattice to incorporate into the model the operation of so-called trusted processes that in the past have always been viewed as annoying exceptions to the existing mandatory security models. It then applies this new model as a better approach to security of mobile code.
Keywords: Mandatory access control, Lattice security models, Biba Integrity model, Bell and LaPadula model, mobile code security.
