Assessment 8 1. Where can you store your public keys or public certificate files in the public domain? Is this the same thing as a Public Key Infrastructure (KI) server? A- Windows Server 2003‚ Standard Edition; Windows Server 2003‚ Enterprise Edition; and Windows Server 2003‚ Datacenter Edition‚ store a certificate locally on the computer or device that requested it or‚ in the case of a user‚ on the computer or device that the user used to request it. The storage location is called the certificate

6 Outline I. The Basics of Public Key Infrastructures A. A PKI is a structure that provides all the necessary components to enable different users and entities to communicate in a secure and a predictable manner. 1. A PKI is made up of hardware‚ applications‚ policies‚ services‚ programming interfaces‚ cryptographic algorithms‚ protocols‚ users‚ and utilities. 2. These components work together to allow communication using public key cryptography and symmetric keys for digital signatures‚ data

In an Internet Banking Financial Institution is Single Factor Authentication acceptable? Why or why not? Yes it can be acceptable because you can buff up security elsewhere. 2. Explain the difference between Positive Verification and Negative Verification? Negative verification is the opposite of positive verification

Tampa FL Instructor: David Marquez 17 April‚ 2014 1. What are the three major categories used to provide authentication of an individual? a) something you know (e.g.‚ a password) b) something you have (e.g.‚ a certificate with associated private key or smart card) c) something you are (a biometric) 2. What is Authorization and how is this concept aligned with Identification and Authentication? a) Authorization is the process of determining whether an entity‚ once authenticated‚ is permitted to

EMAP: Expedite Message Authentication Protocol for Vehicular Ad Hoc Networks ABSTRACT Vehicular Ad Hoc Networks (VANETs) adopt the Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs) for their security. In any PKI system‚ the authentication of a received message is performed by checking if the certificate of the sender is included in the current CRL‚ and verifying the authenticity of the certificate and signature of the sender. In this paper‚ we propose an Expedite Message

Message authentication code provides authentication or proves integrity of a digital message. 4. SHA-1 encryption scheme was broken and was replaced with a third round version of itself. 5. RSA is the first algorithm suited to both signing and encryption‚ and it is now widely used in e-commerce and other public key systems. 6. The entity

S/MIME provides two security services: •Digital signatures •Message encryption S/MIME solutions require a PKI to provide digital certificates with public key/private key pairs and enable certificate mapping in the Active Directory directory service. The S/MIME standard specifies that digital certificates used for S/MIME conform to the International Telecommunications Union (ITU) X.509 standard
