Safety-Critical Software Development in C++intain data confidentiality, clients need to outsource their data to servers in encrypted form. At the same time, clients must still be able to execute queries over encrypted data. One prominent and fairly effective technique for executing SQL-style range queries over encrypted data involves partiti

Such a delay is usually unacceptable because the needs for analyzing attack graphs may change rapidly in defending against network intrusions. An administrator may want to revise an analysis upon observing its outc

An additional feature of our model is the avoidance of direct communications between identity providers and service providers, which provides improved privacy protection for

[17], however, mapping a role based system to a valid MAC configuration is not always possible because certain combinations of permissions that are included in a role’s effective privileges may cause information flow.

The problem arises because some email-control mechanisms like bonds, graph-turing tests, ., inherently leak information, and without discontinuing their use, leakage channels cannot be closed. We formalize the capabilities of an attacker a

We focus on two kinds of access control models: discretionary models, based on access control lists (ACLs), and role-based access control (RBAC) models. For RBAC models, we show that we can specify several variants, including m
