Cloud service providers are often trusted to be genuine, the damage caused bybeing discovered to be attacking their own customers outweighs any benefitssuch attacks could reap. On the other hand, it is expected that some cloudservice users may be actively malicious. In such an open system, each locationmay run code which has been developed independently of other locations (andwhich may be secret). In this paper, we present a typed language which ensuresthat the access restrictions put on data on a particular device will beobserved by all other devices running typed code. Untyped, compromised devicescan still interact with typed devices without being able to violate thepolicies, except in the case when a policy directly places trust in untypedlocations. Importantly, our type system does not need a middleware layer or allusers to register with a preexisting PKI, and it allows for devices todynamically create new identities. The confidentiality property guaranteed bythe language is defined for any kind of intruder: we consider labeledbisimilarity i.e. an attacker cannot distinguish two scenarios that differ bythe change of a protected value. This shows our main result that, for a devicethat runs well typed code and only places trust in other well typed devices,programming errors cannot cause a data leakage.
