Free Essays on Cryptography to Get Inspired & Learn by Example

Cryptography is considered to be different things depending on the peoples’ point of view. Children used to play ciphers and secret languages. This, however, it is not related to this cryptography. The cryptography or strong cryptography should provide a level of privacy, so you can prevent the critical information from decrypting by large organizations: mafia, big corporations and large states. This cryptography in the past was used only for military purposes. But now, with the emergence of the information-oriented society, it becomes a central tool to ensure confidentiality.
As the information society forms, the technological tehniques of total surveillance Continue reading...

Microsoft Windows Access Control

Appropriate Microsoft Windows access controls

The access control of Windows is complex associated with various permission grants. The system assumes that the installation of applications is under Program Files that has a safe default set of permissions. Any application installed in a non-default location goes to C folder. The user can modify the settings to have a Collaborative Access Control List. An administrator should have two accounts one for regular work, and another for administrative work (Homer & Isbell, 2004). The administrator should create user accounts using malware and least privilege where users do not have administrative permissions. An administrator should Continue reading...

Internet Security and Privacy using Cryptography Techniques

This paper attempts to characterize and present some major aspects on Network security and privacy in many sectors or organizations, which could be an issue of growing importance. System Security is the key segment in data security in light of the fact that it is in charge of securing all data passed through arranged machines. System Security mentions to all fittings and programming capacities, attributes, characteristics, operational techniques, responsibility, measures, access control, and managerial and administration approach needed to give a worthy level of security for Hardware, Continue reading...

Research is one of the most delicate things that take place around the world and each and every research institution goes to great extents to ensure that the research they are doing is confidential to them until the time they decide to reveal their findings to the public in general. As a result, institutions that involve themselves in research ought to find the most efficient and most secure method of protecting their information to prevent it from leaking to their rivals, as well as the public. The use of encryptions has been identified to be one of the most Continue reading...

“No Encryption Standards Raises Healthcare Privacy Questions”

Description of the Issue and Its Impact on the Population
In the article, published by the Associated Press, the major issue discussed is lack of encryption standards, with specific regard to Electronic Health Data. It indicates the 1990 Laws that do not require health care service providers to encrypt medical data and the concerns it has raised among different stakeholders such as; Anthem, an Insurance Company. Additionally, the article describes the loopholes existing in Privacy Laws like the HIPPA, which requires medical service providers to encrypt medical data, but do not make it mandatory, thus leading to vulnerability to Continue reading...

Cryptography uses mathematical algorithms to convert plain text information into coded information or cipher. Unlike shared secret cryptography where the same shared key is used for encryption and decryption by the sender and receiver, public key cryptography uses a pair of keys – one publicly available key and the other, a private key known only by the owner of the key. A signatory signs a digital document using a combination of the public and private key, and this document can then be verified using the public key that is publicly available to everyone.

The organization will benefit immensely from the use of PKI owing to the services obtainable from it:

Authentication: the source of a digital document Continue reading...

The security breach at TJX was first discovered on December 18, 2006 which was 18 months after the first intrusion in July, 2005. The breached systems were located in Framingham, and these processed and stored information on checks, credit cards and returned merchandise without receipts. TJX began an internal investigation and hired security consultants – IBM and the General Dynamics Corporation to assist in the investigation. TJX also notified law enforcement agencies and financial institutions such as banks, credit and debit card companies, and check-processing companies of the intrusion. According to banks and other credit card issuing institutions, approximately 94 Continue reading...

Communication Security (ComSec)

INTRODUCTION
Communication security is an important section of modern telecommunication systems where signal intelligences and other methods are used to provide secure communication among peers to be connected. Signal intelligence falls into the category of cryptography where the encrypted signal is collected and analyzed for propagating secure communication. This research work will explain the requirements of communication security and will discuss how signal intelligence can be used in communication security. These solutions can be used practically in communication security of the military services.
Signal intelligence is introduced and evolved by military services where signals from foreign communication systems are Continue reading...

The re a number of technologies that are associated with network security defense. Firstly are those technologies that supports wireless sensor network where many features of sensor networks might aid in tackling the challenge of building network that is secure. The unique feature of sensor network might permit fresh defenses that do not actually exist in conventional network. Some of the wireless technologies for network security defense include SPINS, TINYSEC, and LEAP (Singh, Singh & Singh, 2011).
The security protocol for sensor network (SPINS) is a security building block that is optimized for resource limited environments and communication using wireless Continue reading...
