Application Of A Digital Certificate

With the ever increasing surge of digital communications and transactions, a tougher level of security is essential in order to safeguard the user and their data transactions. Systems, personal computers, mobile phones, servers, and even smart cards are all being used everywhere and there is a need to secure communications. With the influx of data management, there is a clear race between the two challengers in the game known as Information Security between developers and the hackers. PKI was designed to influence the Internet infrastructure for means of communication (Samuelle, 2011). While decreasing antagonistic misuse of data, reducing data theft, and providing an extra layer of trust through key pairs and

Compromised Certificates – stealing certificates to sign malware, encrypt outbound sessions to avoid detection, and Man-in-the-Middle attacks to decrypt sensitive data.

1) Digital Certificates: Digital authentications are settled upon information structures that join qualities of an association with having its relating open key. The key necessity for a Digital Certificate is the reality it should be approved upon by recognition} expert (CA). By being marked by a perceived and trusted specialist an electronic computerized testament gives the certification

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into

33. What is a system of digital certificates, certification authorities (CAs), and other registration authorities (RAs) that verify and authenticate the validity of each party involved in an electronic transaction through the use of public key cryptography? PKI

21.) Digital certificate A digital certificate is an electronic "passport" that allows a person, computer or organization to exchange information securely over the Internet using the public key infrastructure (PKI). A digital certificate may also be referred to as a public key certificate.

a certification authority company provides a digital signature when a high level of security is needed to protect the contents of a database.

Public key infrastructure, known as PKI supports the distribution and identification of public encryption keys which allows users and computers to securely exchange data over the internet and networks to confirm the identity of the other party. Without PKI, sensitive information can still be encrypted and exchanged, but there would be no assurance of the identity of the other party. Any form of sensitive data exchanged over the Internet is reliant on PKI for security.

(Public Key Infrastructure Roadmap for the Department of Defense, Version 5.0, 18 Dec 2000, p.6) The overall IA posture was balanced on the DoD’s Defense in layering strategy allowing the use of multiple solutions of varying assurance levels in which to prevent or contain the consequence of a breach of security. The Defense in layering strategy coined Defense in Depth, consists of five layers: Defense of Computing Environments including the hosts, servers, applications, and operating systems used within DoD local area networks (LANs), Defense of Enclave Boundaries/External Connections at which DoD LANs connect to the wide area networks (WANs) by deploying boundary protection measures to control and monitor access to the internal LANs, Defense of Networks and Infrastructure, including the WANs that are used to interconnect DoD systems and those of its allies and business partners, to ensure the confidentiality of DoD communications and protection against Denial of Service attacks that could disrupt DoD’s ability to communicate prior to or during operational deployments, Attack Sensing, Warning, and Response to protect, analyze, and respond to unauthorized access, intrusions, and cyber attacks at local, regional, and national levels, and Key Management Infrastructure (KMI) services including key management for DoD traditional and more recently public key systems, as well as physical products such as codebooks and authenticators. A component of the KMI is Public Key Infrastructure (PKI), which consists of products and services, which provide and manage X. 509 certificates for public key cryptography. This paper

While various security practices are in place that businesses can utilize, Public Key Infrastructure (PKI) has become a vital security foundation for Identity and management across the organizations. PKI empowers individuals and organizations to use various secure Internet applications. For instance, secure and lawfully restricting

From the viewpoint of data security, which has always been an important form of quality of service, Cloud computing surely poses new challenging security threats for number of reasons. Firstly, traditional cryptographic primitives for the purpose of data security protection cannot be straight accepted due to users loss control of data under cloud computing. Therefore, verification of correct data storage in the cloud must be attended without accurate knowledge of the whole data. Considering different kind of data for every user stored in the cloud and the requirement of long term continuous security of their data safety, the problem of checking correctness of data storage in the cloud becomes even more challenging.[1]

Authentication is the only method which protects information or data of an individual or organization from a second party to access. Based upon the confidentiality of that particular data or information, the level of authentication depends. Now-a-days, all this data and information what we are talking about is getting digitized all around the world. For this digitized data or information to be secure, a proper authentication procedure must be set. This arise the need for an authentication secret which belongs to the category “Something we know” to come into picture. These secrets authenticate each secret holder as the authorized legitimate user to access their particular account. Technology is

Cybercrime has become a fast growing concern for the 21st century as businesses, institutions and individuals grow into an interconnected web of computer networks. Online business transactions, along with the sharing of personal information, are vulnerable to a host of disasters that can reap economic and social havoc. Some sources say that today, cybercrime costs more than $1.0 trillion to society--Global Industry Analysts, Inc. forecasted the world cyber security market to reach $80 billion by 2017 (Gale, 2011).
