Public Key Infrastructure (PKI) Public Key Infrastructure (PKI) is a security architecture that has been introduced to provide an increasedlevel of confidence for exchanging information over an increasingly insecure Internet. PKI may involve the use of methods‚ technologies and techniques that together provide a secure infrastructure. PKI involves the use of a public key and private key pair for authentication and proof of content. A PKI infrastructure is expected to offer its users the following

Public-Key Infrastructure RFC 2822 (Internet Security Glossary) defines public-key infrastructure (PKI) as the set of hardware‚ software‚ people‚ policies‚ and procedures needed to create‚ manage‚ store‚ distribute‚ and revoke digital certificates based on asymmetric cryptography. The principal objective for developing a PKI is to enable secure‚ convenient‚ and efficient acquisition of public keys. The Internet Engineering Task Force (IETF) Public Key Infrastructure X.509 (PKIX) working group has

Study 2: Public Key Infrastructure You are the Information Security Officer at a small software company. The organization currently utilizes a Microsoft Server 2008 Active Directory domain administered by a limited number of over-tasked network administrators. The remainder of the organization comprises mostly software developers and a relatively small number of administrative personnel. The organization has decided that it would be in its best interest to use a public key infrastructure (PKI) to

Include the design and reasoning for using the selected encryption strategy. Have a secure network takes a lot of work and has to be monitored 24 hours a day 7 days a week. There are many different ways to go about this topic the one I am going to pick is a public key infrastructure (PKI). One security options that can be used is the

1) How does the public key cryptography work? Explain in detail? 1. Public-key‚ what it is Public-key refers to a cryptographic mechanism. It has been named public-key to differentiate it from the traditional and more intuitive cryptographic mechanism known as: symmetric-key‚ shared secret‚ secret-key and also called private-key. Symmetric-key cryptography is a mechanism by which the same key is used for both encrypting and decrypting; it is more intuitive because of its similarity with

The study of Public-Key Cryptography Enabled Kerberos Authentication by Sufyan and Mayada (2011) attempt to extend the Kerberos authentication protocol standard to support public key cryptography. This is to eliminate some of the limitations in the standard Kerberos protocol which uses symmetric key cryptography. There are 3 extensions to add support of public-key cryptography at different stages of the Kerberos framework‚ which are PKINIT‚ PKCROSS and PKTAPP. Public-Key Cryptography for Initial

QUESTION BANK 13.1 13.2 Define E-commerce. What are the different types of E-commerce? Explain B2B E-Commerce using an example of a book distributor who stocks a large number of books‚ which he distributes via a large network of book sellers. Assume that the distributor has stocks of books of a large number of publishers and book sellers order books as and when their stock is low. Distributors give 1 month’s time to booksellers for payment. 13.3 Explain B2C E-Commerce of a customer reserving airline
