Dynamic sharing of the system resources in multilevel secure system
Miguel Angel Reyes
Written in English
This thesis represents a preliminary step in the development of a reliable application program simulating an operating system which handles several multi-security-level users dynamically sharing system resources in the Gemini Trusted Multiple Microcomputer Base machine. The proposed design presents the necessary steps to follow when working in a multilevel configuration. The use of primitives that support the application design are explained along with a description of the implementation of this application using Janus/Ada language. In addition, security constraints are identified and system test results are described. Keywords: Computer programming; Systems engineering.

The rapid development and wide application of computer network is a new challenge to information security and network security. Traditional security models and single security technology can not keep up with the change of complex network structure and alterable intrusion measure. Based on analysis of some classical security models and technologies, we think network security is a kind of Author: Kai Qi Fan.

this paper, we propose a secure data sharing scheme for dynamic members. First, we propose a secure way for key distribution without any secure communication channels. Second, our scheme can achieve fine-grained access control, any user in the group can use the source in the cloud and revoked users cannot access the cloud again. failed to achieve the efficient as well as secure method for data sharing for groups. To provide the best solutions for the problems imposed by existing methods, recently the new method was presented called MONA . This approach presents the design of secure data sharing scheme, Mona, for dynamic groups in an untrusted cloud.
Unfortunately, sharing data in a multi-owner manner while preserving data and identity privacy from an untrusted cloud is still a challenging issue, due to the frequent change of the membership. In this paper, we propose a secure multi- owner data sharing scheme, named MONA, for dynamic groups in the cloud. Contact Us. Dynamic Systems Resources, Inc. E.

With Dynamic System Resources, you can build a powerful Information Technology system that gives you the flexibility to reach your strategic and performance goals—ultimately ramping-up your bottom line.
Characteristics of a multilevel-secure system include the following: The system controls access to resources. The system does not allow a storage object to be reused until it is purged of residual data. The system enforces accountability by requiring each user to be identified, and creating audit records that associate security-relevant events.
An MLS workflow management system that allows a user to program multilevel mission logic, to securely coordinate widely distributed tasks, and to monitor the progress of the workflow across classification levels is by: sharing data in a multi-owner manner while preserving data and identity privacy from an untrusted cloud is still a challenging issue, due to the frequent change of the membership.
We propose a secure multiowner data sharing scheme, named Mona, for dynamic groups in the cloud. By leveraging group signature and dynamic broadcast. Unfortunately, sharing data in a multi-owner manner while preserving data and identity privacy from an un trusted cloud is still a challenging issue, due to the frequent change of the membership.
In this paper, we propose a secure multi owner data sharing scheme, named Mona, for dynamic groups in the cloud. Multics implemented a single-level store for data access, discarding the clear distinction between files (called segments in Multics) and process memory of a process consisted solely of segments that were mapped into its address read or write to them, the process simply used normal central processing unit (CPU) instructions, and the operating system took care of making sure Developer: MIT, GE, Bell Labs.
Also, the smaller "gap" is, the more timely the DFM can be in response to changes in the job environment. Defining the variable "gap" is troublesome, for although there is value in keeping it flexible, it is Dynamic file movement in multilevel storage systems difficult to define it to fluctuate with the changes in the by: 1.
MODBLKS resources are so named because when dynamic resource definition is not used, these resources are generated into the MODBLKS data set by the IMS system definition process.
MSC resources, which include definitions for MSC physical links, logical links, logical link paths, and remote logical terminals. The secret sharing scheme in multilevel access structures uses a sequence of related Shamir threshold schemes with overlapping shares and the secret.
The secret sharing scheme in compartmented access structures applies Shamir schemes first to recover partial secrets and second to combine them into the requested by: form its desired tasks.
The allocation of system resources is dynamically managed to locally maximize utility at each level of the system hierarchy with individual controllers de-ployed for the whole system and all missions and its strings.
The general philosophy for the control system is a bottom-up approach to dynamic resource management. A secure multilevel object oriented database management system which maintains data confidentiality and optimizes data integrity. All requests for database operations are mediated through an access validation monitor (AVM).
The AVM is responsible for performing the following duties: applying mandatory and discretionary access control rules for each request it services to ensure the request is Cited by: The second one (Kang, Froscher et al. ) describes a multilevel secure (MLS) workflow system to enable distributed users and workflow applications to cooperate across classification levels.
MLS. Multilevel secure network access system. A workstation can access information having two or more different security classifications stored on servers within networks. Servers of one security classification are isolated from servers of another security classification by each type of server being disposed within its own isolated network or network by: Multilevel Security (MLS) is a capability that allows information with different classifications to be available in an information system, with users having different security clearances and Author: Walid Rjaibi.
We consider in particular how a multilevel system can allocate resources among levels without covert channels that compromise security and without inefficiencies that leave the system impractical. We describe the problems with dynamic allocation and identify three alternative strategies for secure and practical resource allocation: static.
