Information integrity policies are traditionally enforced by access control mechanisms that prevent unauthorized users from modifying data. However, access control does not provide end-to-end assurance of integrity. For that reason, integrity guarantees in the form of noninterference assertions have been proposed. Despite the appeals of such information-flow based approaches to integrity, that ...

Enforcing privacy on public clouds through access control mechanisms are currently based on Single Layer Encryption. Under Single Layer Encryption, data owners should upload data on the cloud after encrypting them and have to re-encrypt the data whenever access policies or user profiles are changed. This could increase the communication and computational costs at data owners. A better approach ...

Most of current access control systems are not expressive enough for current applications, in the sense that they cannot express several access control policies required by them. Most of these applications have no choice but to build their owned very specific access control systems completely independently from other applications running on the same environment, which entails potential incohere...

This manuscript presents an intercomparison exercise of tropospheric HCHO retrieved from satellites measurements using several products obtained from independent retrieval approaches. In order to validate the products, the authors use aircraft observations during the short term field deployment of SEAC4RS in the Southeast of the US. This is an important validation effort. In general, the paper ...

This paper describes a novel parameterization for lightning-produced NOx (LNOx) developed for cloud resolving models (CRM), a topic appropriate for publication in ACP. In addition, sensitivity studies are carried out in large detail to select the most important parameters and to point out which parameter values fit the observations best. Such comprehensive sensitivity studies concerning LNOx pa...

worthy. Bellow there are general and particular comments to help the authors in improving their manuscript. According to these comments, I consider that the manuscript requires substantial revision before to be accepted for publication in ACP. General comment The experimental data set is really interesting, but the study will benefit from a more exhaustive analysis of some aspects like the PBL ...
