2 Chapter 4 Key Distribution and User Authentication
3 No Singhalese, whether man or woman, would venture out of the house without a bunch of keys in his hand, for without such a talisman he would fear that some devil might take advantage of his weak state to slip into his body. The Golden Bough, Sir James George Frazer
4 Symmetric Key Distribution using symmetric encryption For symmetric encryption to work, the two parties to an exchange must share the same key, and that key must be protected from access by others Frequent key changes are usually desirable to limit the amount of data compromised if an attacker learns the key Key distribution technique The means of delivering a key to two parties that wish to exchange data, without allowing others to see the key
5 Key Distribution For two parties A and B, there are the following options: A key can be selected by A and physically delivered to B A third party can select the key and physically deliver it to A and B If A and B have previously and recently used a key, one party could transmit the new key to the other, using the old key to encrypt the new key If A and B each have an encrypted connection to a third party C, C could deliver a key on the encrypted links to A and B
6 Kerberos Key distribution and user authentication service developed at MIT Provides a centralized authentication server whose function is to authenticate users to servers and servers to users Relies exclusively on symmetric encryption, making no use of public-key encryption Two versions are in use Version 4 implementations still exist, although this version is being phased out Version 5 corrects some of the security deficiencies of version 4 and has been issued as a proposed Internet Standard (RFC 4120)
7 Kerberos version 4 A basic third-party authentication scheme Authentication Server (AS) Users initially negotiate with AS to identify self AS provides a non-corruptible authentication credential (ticket granting ticket TGT) Ticket Granting Server (TGS) Users subsequently request access to other services from TGS on basis of users TGT Complex protocol using DES

13 Table 4.1 Summary of Kerberos Version 4 Message Exchanges
14 Kerberos Realms Kerberos realm A set of managed nodes that share the same Kerberos database The Kerberos database resides on the Kerberos master computer system, which should be kept in a physically secure room A read-only copy of the Kerberos database might also reside on other Kerberos computer systems All changes to the database must be made on the master computer system Changing or accessing the contents of a Kerberos database requires the Kerberos master password A Kerberos environment consists of: A Kerberos server A number of clients A number of application servers
15 Kerberos principal A service or user that is known to the Kerberos system Each Kerberos principal is identified by its principal name A service or user name An instance name A realm name Principal name Principal names consist of three parts
16 Differences between versions 4 and 5 Environmental shortcomings Technical deficiencies Encryption system dependence Internet protocol dependence Message byte ordering Ticket lifetime Double encryption PCBC encryption Session keys Password attacks Authentication forwarding Interrealm authentication
17
18 Key distribution using asymmetric encryption One of the major roles of public-key encryption is to address the problem of key distribution There are two distinct aspects to the use of public-key encryption in this regard: The distribution of public keys The use of public-key encryption to distribute secret keys Public-key certificate Consists of a public key plus a user ID of the key owner, with the whole block signed by a trusted third party Typically, the third party is a certificate authority (CA) that is trusted by the user community, such as a government agency or a financial institution A user can present his or her public key to the authority in a secure manner and obtain a certificate The user can then publish the certificate Anyone needing this user s public key can obtain the certificate and verify that it is valid by way of the attached trusted signature
19
20 X.509 Certificates ITU-T recommendation X.509 is part of the X.500 series of recommendations that define a directory service Defines a framework for the provision of authentication services by the X.500 directory to its users The directory may serve as a repository of public-key certificates Defines alternative authentication protocols based on the use of public-key certificates Was initially issued in 1988 Based on the use of public-key cryptography and digital signatures The standard does not dictate the use of a specific algorithm but recommends RSA
21
22
23 Obtaining a user s certificate User certificates generated by a CA have the following characteristics: Any user with access to the public key of the CA can verify the user public key that was certified No party other than the certification authority can modify the certificate without this being detected Because certificates are unforgeable, they can be placed in a directory without the need for the directory to make special efforts to protect them
24
25 Revocation of certificates Each certificate includes a period of validity Typically a new certificate is issued just before the expiration of the old one It may be desirable on occasion to revoke a certificate before it expires for one of the following reasons: The user s private key is assumed to be compromised The user is no longer certified by this CA; reasons for this include subject s name has changed, the certificate is superseded, or the certificate was not issued in conformance with the CA s policies The CA s certificate is assumed to be compromised
26 X.509 Version 3 Includes a number of optional extensions that may be added to the version 2 format Each extension consists of: An extension identifier A criticality indicator An extension value The certificate extensions fall into three main categories: Key and policy information Subject and issuer attributes Certification path constraints
27 Key and policy information These extensions convey additional information about the subject and issuer keys, plus indicators of certificate policy A certificate policy is a named set of rules that indicates the applicability of a certificate to a particular community and/or class of application with common security requirements Includes: Authority key identifier Subject key identifier Key usage Private-key usage period Certificate policies Policy mappings
28 Certificate subject and issuer attributes These extensions support alternative names, in alternative formats, for a certificate subject or certificate issuer and can convey additional information about the certificate subject to increase a certificate user s confidence that the certificate subject is a particular person or entity Includes: Subject alternative name Issuer alternative name Subject directory attributes
29 Certification path constraints These extensions allow constraint specifications to be included in certificates issued for CAs by other CAs The constraints may restrict the types of certificates that can be issued by the subject CA or that may occur subsequently in a certification chain Includes: Basic constraints Name constraints Policy constraints
30
31 PKIX Management functions Functions that potentially need to be supported by management protocols: Registration Initialization Certification Key pair recovery Key pair update Revocation request Cross certification Alternative management protocols: Certificate management protocols (CMP) Designed to be a flexible protocol able to accommodate a variety of technical, operational, and business models Certificate management messages over CMS (CMC) Is built on earlier work and is intended to leverage existing implementations
32 Identity Management A centralized, automated approach to provide enterprise wide access to resources by employees and other authorized individuals Focus is defining an identity for each user (human or process), associating attributes with the identity, and enforcing a means by which a user can verify identity Central concept is the use of single sign-on (SSO) which enables a user to access all network resources after a single authentication Principal elements of an identity management system: Authentication Authorization Accounting Provisioning Workflow automation Delegated administration Password synchronization Self-service password reset Federation
33
34
35 Standards The Extensible Markup Language (XML) Appear similar to HTML documents that are visible as Web pages, but provide greater functionality Includes strict definitions of the data type of each field Provides encoding rules for commands that are used to transfer and update data objects The Simple Object Access Protocol (SOAP) Minimal set of conventions for invoking code using XML over HTTP Enables applications to request services from one another with XML-based requests and receive responses as data formatted with XML WS-Security A set of SOAP extensions for implementing message integrity and confidentiality in Web services Assigns security tokens to each message for use in authentication Security Assertion Markup Language (SAML) An XML-based language for the exchange of security information between online business partners Conveys authentication information in the form of assertions about subjects
