Correctness of ‘broken

Correctness of broken . The output acc = broken should never occur in disputes. The interest group consists of the court in this dispute. [Pg.93]

The idea is that there may be special users who are held responsible if the output broken occurs. Such people are called risk bearers. For instance, an insurance may have to pay up in this case, or the party that has introduced the signature scheme, or always the recipient and not the signer. In this case, the correctness of broken is only required in the interest of the court in that dispute plus at least one risk bearer, and the original requirements of the signer and the recipient are relaxed so as to allow the output broken even for the degree low. [Pg.94]

The correctness of broken is required in the interest of the court in the given dispute and any risk bearer. Hence any single risk bearer can guarantee that the output broken does not occur (with the degree low). [Pg.95]

Fail-stop security has been described in Section 5.2.9 the degree low is now computationally and high is information-theoretically. Thus the fall-back requirements of both the signer and the recipient on disputes are fulfilled information-theoretically and the correctness of broken computationally. [Pg.120]

If the requirement of the signer on disputes (or the fall-back requirement) is fulfilled without error probability, the requirement of the recipient on disputes (or the correctness of broken ) is not fulfilled at all. [Pg.123]

The same argument apphes to the fall-back requirement of the signer, if there is a fail-stop property If that were error-free, the court s output in the dispute would be FALSE or broken with probability 1. The former contradicts the requirement of the recipient, the latter the correctness of broken . [Pg.124]

The main variations are in the number of risk bearers and how the risk bearers participate in initialization, and in the number of recipients and the consequences on testing signatures. Furthermore, the existing schemes vary in the message space, the cryptologic assumption that the correctness of broken relies on, and in efficiency. [Pg.127]

Fail-stop security without further attributes means that the correctness of broken is required in the interest of each court individually. However, schemes with fewer special risk bearers (see Section 5.2.9) are important, because they can be much more efficient. For an overview, see Figure 6.2. [Pg.127]

Security parameters. As some requirements on a fail-stop signature scheme have to be fulfilled information-theoretically and others only computationally, it is natural to consider two security parameters. They are called a and k, where a measures the information-theoretic security and k the computational security. The primary role of cr is that the error probability in the fail-back requirement of the signer on disputes decreases exponentially with a. In other words, a determines the probability that the signer is cheated with unprovable forgeries. The primary role of k is to ensure the correctness of broken , i.e., the larger k is, the harder it should be to compute valid proofs of forgeries (and thus forgeries in the first place). [Pg.151]

The requirements are now considered one by one. The two original requirements on disputes from Section 5.2.7 can be omitted According to Section 5.2.9, Combinations , they follow from the fall-back requirements on disputes and the correctness of broken in full fail-stop signature schemes, and in the case with special risk bearers as accountable centres, they were omitted on purpose. [Pg.161]

Correctness of broken means that a correct entity of a court should not produce the output broken in a dispute or a transfer of a proof of forgery. With the structure assumed for standard fail-stop signature schemes, this output depends on an application of verify, hence the requirement means that no valid proofs of forgery should occur. This requirement is fulfilled computationally only, and if there are special risk bearers, one of their entities is assumed to be correct. [Pg.163]

Lemma 7.6. If a standard fail-stop signature scheme guarantees the correctness of broken against attackers that only take part in one initialization and one dispute, it also guarantees this requirement against general active attacks. ... [Pg.164]

At the level of entities, this argument seems to need an honest court, which is not assumed here. However, the conventional definition of the correctness of broken , as sketched in the previous subsection and formalized in Definition 7.11, only says that it should be infeasible to compute a valid proof of forgery, as long as any risk bearer is honest. [Pg.165]

Similarly, the correctness of broken for such transfers is the same as the normal correctness of broken for disputes. [Pg.168]

Iteration solutions were first proposed by Thiele and Geddes (Tl) in 1933. In this method, all temperatures and flows must be estimated before the solution can begin. The solution is broken into three parts first, solution of the mass-balance equations under the estimated flows and temperatures second, correction of the temperatures and third, correction of the flows. Assuming values for all temperatures and flows reduces the set of mass-balance equations shown in Table I to a linear set of equations which can be solved for the compositions at each point. Because the starting assumptions are completely arbitrary, the compositions will undoubtedly be wrong (the liquid and vapor mole-fractions will not sum to unity), and better values of temperature and flows must then be obtained for use in the next iteration. [Pg.287]

These results may be of the correct order with a reasonable estimate of the magnitude of the continuum term using the scaling expression for monovalent ions. They are therefore in the range 430-520 kJ/mole (102-125 kcal/mole) before conventional correction of about 84 kJ/mole (20 kcal/mole) to account for broken hydrogen bonds,... [Pg.253]

Fig. 37. Experimental values for Tb(OH)3 in the ordered state at 2.6K, after making extinction corrections. The broken curve is derived from nonrelativistic free ion wave functions. The solid curve is the best fit to the experimental points and falls directly on the relativistic free ion form factor. All curves are normalized to a magnetic moment of 8.9 jUs/Tb atom [after Ref. (757)]... Fig. 37. Experimental values for Tb(OH)3 in the ordered state at 2.6K, after making extinction corrections. The broken curve is derived from nonrelativistic free ion wave functions.
