Centralized certification is denoted X509 certification, using the name of the ITU-T Recommendation [11] that defines the framework for authentication in open systems X509 is identical to ISO/IEC 9594-8, a joint standard from the ISO and the IEC ANSI also ratified a corresponding standard known as ANSI X957 [91] The focus of the following presentation will be on X509 certificates For details on certification practices, the interested reader is also invited to consult specialized books on certification, for example, Ford and Baum [92, pp 357 404] whose first author was at the time a manager in VeriSign, one of the key players in certification The ITU-T and the ISO/IEC have established a whole series of recommendations to describe the operation of a public key infrastructure (PKI) These are: X500 (ISO/IEC 9594-1) [66] for a general view of the concepts, the models, and the services X.

In Part II of the book we discuss alternative de nitions of risk, de ne forward- versus backward-looking risk, and the available methods of inferring the risks taken from the time series of historical returns. We will also examine the evaluation of absolute risk in a mean-variance framework where risk is proxied by the standard deviation of returns. We then look at measures where risk is de ned as the potential of losing money, or downside risk. Finally, we cover the methods used to determine the incremental risk taken by the manager over the risk implied by the benchmark, or benchmark relative risk. We examine the use of regression analysis and tracking error to measure relative risk.

501 (ISO/IEC 9594-2) [93] for the different models used in the Directory X509 (ISO/IEC 9594-8) [11], which defines the framework for authentication through public key cryptography using identity certificates and attribute certificates X511 (ISO/IEC 9594-3) [94], which defines the abstract services of the Directory (search, creation, deletion, error messages, etc) X520 (ISO/IEC 9594-6) [95] and X521 (ISO/IEC 9594-7) [96], which, respectively, specify selected attribute types (key words) and selected object classes to ensure compatibility among implementations These recommendations specify services, protocols, messages and object classes to carry out the following functions: Retrieval of credentials stored in the Directory by a directory user agent (DUA) at the client side and a directory system agent (DSA) at the server s side with the Directory Access Protocol (DAP) defined in X519 (ISO/IEC 9594-5) [97].

improving on existing technologies and methodologies while at the same time creating competitive pressure on prices. In other words, better technology became available faster and cheaper. As you will see later in the chapter, there are actually online databases that provide for free what would have cost thousands of dollars just a decade ago.

Distributed searches and referrals among directory system agents with the Directory System Protocol (DSP) of X518 (ISO/IEC 9594-4) [98] Information sharing among directory system agents through replication of the directory using the Directory Information Shadowing Protocol (DISP) of X525 (ISO/IEC 9594-9) [99] The relationship among these different protocols is shown in Figure 513 X500 [66] is the basis for security directory services in the TMN, as defined in ANSI T1252 [100], should such security be deemed necessary T1252 relies on the X500 Directory for distribution of certified public keys to authorized entities In IP networks, a simplified version of DAP, the LDAP, is often used for communication between user agents and system agents LDAP is the output of the Public Key Infrastructure (X509) (PKIX) working group of the IETF and is defined in RFC2251 [101] The main simplifications are as follows: 1.

LDAP carried directly over the TCP/IP stack, thereby avoiding some of the OSI protocols at the application layer..

PDH transmission systems provide a very cost-effective means of transporting a large number of telephone circuits, due to reductions in the cost of integrated circuits and advances in optical technology The current PDH evolved mainly in response to the demand for plain voice telephony The availability of cheap transmission bandwidth led to the proliferation of new, non-voice, telecommunication services, most of them aimed at the business customer New service offerings resulted in new requirements to be met by the network, such as flexibility of providing new connections or dynamically distributing the capacity As shown in Figure 314 there are three kinds of digital hierarchy recommended by ITU-T.
