In military environment the data has to be transmitted in secured and faster way, even the network is suffer from frequent partitions and intermittent network connectivity. To transmit the data faster and in secure way Disruption-tolerant network is useful, which allow nodes to communicate each other even in this network environment. Rou and Chua h introduce external storage node in disruption tolerant network which stores data for allowing only authorized users to access the data. This Military Network requires sender to entrust their valuable data to users, there have been increasing security and privacy concerns on data. Several schemes employing attribute-based encryption (ABE) for access control over data. However, most of …show more content…
The key-authorities generate private key to the users by giving its own master secret key. When multiple key-authorities are available then each key-authority generates their own attributes individually with their own master secret key. Thus key-authorities are in the first place to keep the data confidential. This is the first security requirement. Data Confidentiality is not enough for secure data transmission in the military environment. Flexible and Fine-Grained access control is also required to make data more secure for the military environment. The information about the particular organization is required to be protected. In this case, access control of sensitive data is done by allowing users to access the data based on their roles. For example, the information about the colleges will be viewed based on their roles such as students, faculty, and higher level …show more content…
In military environment users are r-evocated, in this cases also data has to be transmitted in a secured way. To achieve this, key-authorities has to regenerate the keys for the revoked users. By regenerating the keys, the attribute in access structure changes. When the same attribute set is shared by the multiple users then all the users who are accessing the same data can also effected for changing an attribute key. This implies that revocation of any attribute (i.e., rekeying) or single user (i.e., user changed location) in a group will affect the other user in the group. To avoid this fast redistribution has to done if there are any changes in an
Security and privacy Issues Depending on the field of application, and in some cases, it may become necessary to prevent unauthorized persons from reading or writing data stored on or transmitted from tags. To this end, encryption must be ensured at all interfaces where data could be intercepted or transmitted (on the medium itself, as well as tag–reader and reader–host communication)
The whole data from the insurance providers, doctor’s data, patient’s history need to be maintained in a secure manner. The access permissions are given by the team to certain level of people where as if there are any changes in the structure of the permissions only the IT team are responsible in changing the permissions for accessing the PHI records. Likewise, the confidentiality of data is also taken care by the
Company must also develop a clear structure for granting employees access to sensitive information. Not all employees need such data in order to fulfill their everyday job responsibilities. For those who need admission to sensitive information, a strong authentication mechanism must be developed, which cannot be bypassed. This will ensure that only authorized users are accessing compromising data.
The administration of data security depends on three unique ranges of responsibility. These are most certainly not regularly connected or facilitated as their management is set in various authoritative structures which may not converse with each other.
The database runs on the Oracle 11g platform and the CIO has task me to prepare a responsive database security plan. If personnel data is compromise identity theft can ensue and millions of dollars will be lost in repairing the wronged individual and rebuilding soldiers’ confidence in Department of Defense commitment to protecting their private information. It is not just the soldier information stored here but every dependent information and legal responsibility of single soldiers. The Standard Installation Division Personnel System Version 3 (SIDPERS-3) is a Standard Army Management Information System developed in 1991 with more automated personnel actions than ever before. The system consists of a relational data base, application software written in Ada, and a hardware suite. The hardware architecture is a host-based design with a
This paper will discuss a better way to control user access to data is to tie data access to the role a user plays in an organization. It will cover the value of separating duties in the organization. Then discuss the value of using roles to segregate the data and system access needs of individuals in the organization. Then describe in detail why a role-based access control system (RBAC) would be the best way to accomplish this. Finally, how to handle distributed trust management issues for users going to or from business partner networks.
The task of implementing a protection scheme that will provide controlled access to specific files in a system is not only an important but also a necessary task to ensure that the integrity as well as the availability of that file is maintained throughout. This paper is designed to put into perspective a protection scheme to facilitate the scenario where a system has 5000 user and 4990 of those users will need to have access to a particular file within the system. It will also provide clarity on Access control list (ACL’s) their roles as well as the different flavors available. It will also try to prove that proper implementation and utilizations of groups within a security scheme provides not only organization and
The 21st century came accompanied by different worldwide security’s challenges. In this complex environment the U.S. must be able to use efficiently all instruments of power to defend the national interests. Now than ever the U.S. military power must be prepared to defeat the enemy using air, land, and sea. Thus, the transition of troops from the sea to the shore will remain an essential way to achieve a position of advantage over the forces hostile to U.S. interests. Frequent concerns of other countries related to improvement of anti-amphibious and amphibious operations highlight the importance of these kind of warfare in the future conflicts. Today’s concern is not about the possession of amphibious capabilities, but about the
After the attack happened the government realize that the u.s. is not safe from terrorism so it took action in their own hands. To keep the US safe from any other text the government increase the security systems of all airports and any other ways of transportation. This will help the US identify any terrorist and prevent any other disasters but it also made many people insecure about going through these steps of security and entering a country where terrorists has to be so serious and it includes many steps of
Encryption keys should never be stored in the same place as encrypted data. The keys used for encrypting sensitive customer data should be managed effectively by periodic key rotation and re-encryption of data with new keys.
For instance, the design has servers that verifies and validates through activate directory of users. Through active directory, access to specific applications/databases is determined. In addition, encryption and firewall rules will further enhance the security of data. Moreover, 2-factor authentication feature is designed for remote users accessing EMRS database from remote locations.
The United States military is a trusted entity however it’s very powerful and possesses the capabilities to become tyrannical without sufficient supervision and control.
Due to emerging technologies such as big data, cloud platform and use of internet in day to day activities has led to security concerns for various end users. The transfer and storage of information is a crucial part in many business processes, industrial activities and also in military regime. The information could be in forms such as text data, video, audio, image or e-mail. Cryptography is a method to ensure the security and privacy of data transfer process. Data acquisition is the process of acquiring data accurately with minimum loss of signal being acquired and storing it for further use. Data acquisition and information protection is important in military applications. In the paper, a secure data acquisition system for military application is designed. The FPGA platform is used for implementation of the system design.
Proper access controls are imperative within all HOC’s networks and facilities. HOC is a nonprofit housing organization that deals with a lot of sensitive information because NASA critical to the clients security in many cases. This is way access to information must be controlled on a strict need to know basis in order to protect the client and the organization.
Abstract— Data de-duplication is one of essential data com-pression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting de-duplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. The main motivation behind using this technique is making convergent encryption practical to capably and consistently manage a huge number of convergent keys and achieving competent and consistent key management in secure de-duplication. At we first introduce a baseline approach in which each user holds an independent master key for encrypting
