Public key infrastructure

Public key infrastructure is the combination of software, encryption technologies and services that enables enterprises to maintain the security of their business transactions on over the internet. It integrates digital certificates, public key cryptography and certification authorities into a complete enterprise-wide network security architecture. It is also defined as a set of roles, policies and procedures needed to create, revoke digital certificates and manage public-key encryption. It is used to bind public keys to entities, enables other entities to verify public key bindings, and provides the services needed for ongoing management of keys in a distributed system [1]. Public key infrastructure allows one to do business over the internet…

Public Key Infrastructure is a comprehensive subject that is constantly developing to meet high growing demands of the business word. PKI is one of the most effective way for securing networks. The encrypted information that is sent is delivered using a public key. An individual is able to provide the public key to the sender, or the key can be retrieved from the directory from where it was published. PKI works in concert of other security mechanisms to help protect vital information (Weise,…

repository or central database and trusted third party Central authority(CA) are used to revoke, issue and store the keys. There is always a risk that these centralized infrastructure can be violated. Hence, Blochcain can be use to to reduce the risks of storing PKI on centralized infrastructure. Here the Data(Keys) will be distributed across the blochchain network[3] In the 2nd section we will go through the introduction of blockchain, In the 3rd Section, we will see how blockchain protects…

in some kind of communication or requesting access to the system is who, or what, they are professed to be (Rouse, n.d.). The three most common categories are often described as something you know, something you have and lastly something you are (Rouse, n.d.). So if Linen Planet server was requiring as second factor of authentication with say such as a key fob, an employee ID card or common access card (CAC), the entire compromise would have been impossible. Even with the Linen Plant use of…

certificate there will also be an email certificate used for encrypting email traffic using a PKI system. Emails will also be required to be digitally signed ensure users are who they say they are. Users requiring access to the classified network will be issued an additional access card serving the same purposes for digital certificate use. Connections to the wireless network will require the same 802.1x configuration as the wired network. This will include users who decide to bring their own…

signatures prevent persons from acting as the originator of a specific document, which is comparable to forgery on a printed text. Authentication is the primary and most critical line of defense in a system and public networks. It is now common in many stores where credit card payment can be electronically signed using a stylus. Digital signatures, however, similar to conventional signatures, can be risky; once a digital signature is exposed to the populace, it is bound to be fabricated.…

over 1.34 billion people who populate India, 72.2 percent live in 638,000 villages while the remaining 27.8 percent live in only 5,480 towns and urban agglomerations (Population of India 2016, 2016). While urban cities have some paved roads and public transportation means such as trains and subways, much of the country is still exceedingly rural and lacks modern roadways. Very few cities of India have an adequate public transport system (Singh S. K., 2012). A Minneapolis-based company, Bepex,…

Lima, the capital of Peru failed to render safe water services to all of its residents, especially those with low-incomes. The author stated that around 8.5% of the residents receive water from water trucks, 3.9% from public fountains and 4.3% from boreholes or watercourses. The piped water service is available for only a few hours every day and around 90% of the sewage remains untreated in many parts of the city. The country has become one of the main laboratories in Latin America for…

Critical Infrastructure (CI) is very important because the nation relies on it to carry out its essential activities. Since there are many essential activities that must be carry out at all times across the nation, CI has been divided into 16 different CI sectors (Department of Homeland Security, 2017). While each sector is different and perform different functions, all CI sectors are interdependent. That means that each CI sector relies on the functions of other CI sector(s) in order to be able…

Roofer, a person who puts shingles on the roof and can also do other side jobs, is a career I wish to pursue because I have experience with it from working over the summers. Another reason is that my Dad owned how own roofing business and I would like to continue it. Then the last reason is that I actually enjoy the job. I’ve been interested in becoming a roofer ever since I seen my Dad doing it. The only thing I’m not so excited for is how hard the job is on the body. Other than that I…
