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

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

Case 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

P1- Causes of war and conflict where I will explain and give examples of a variety of causes or war and conflict 1. Conflicts arise when people are competing for the same resources (such as territory‚ jobs and income‚ housing) when they aren’t fairly distributed or when there aren’t enough to go round. The same applies to natural resources (cultivable land‚ fresh water). 2. Conflicts arise when the people are unhappy with how they are governed. The most common conflicts occur when a particular

Nutritional Health Explaining the terms: food‚ diet‚ meals and snacks‚ nutrients Food: Food is a nutritious substance that people or animals eat or drink in order to carry on life and growth. Food has been categorised as carbohydrates‚ including fibre‚ protein‚ fat and vitamins and minerals. Food allows us to keep on living. For example bread contains carbohydrate‚ meat contains protein‚ milk contains fat but it depends what milk you take‚ fruit and vegetables both contain vitamin and minerals
