This study investigates relationships between public universities in Thailand, which are quite heavily subsidized by the government in terms of funding, and the government from the perspective of agency theory. We exemplify these results with the computation of discrete logarithms over a field GF(\(p^2\)) whose cardinality is 180 digits (595 bits) long. The aim of this work is to investigate the hardness of the discrete logarithm problem in fields GF(\(p^n\)) where \(n\) is a small integer greater than \(1\). We also propose an efficient algorithm of the Ate pairing on these curves.

SOTWARE IMPLEENTATION WITE APER FIVE CHALLENGES TO SOFTWARE IMPLEMENTATION AND HOW TO AVOID THEM AND REALIZE REAL ROI AS A RESULT Implementing a new software solution carries with it a number of challenges. This paper is proposed a combined casedabased and ruleabased metadata extraction approach to solve these issues. The two input groups of the pairing function are groups of elliptic curve points, while the target group lies in the multiplicative group of a large finite field. The (H)IBE protocols available in the literature are generally shown to be secure against chosen plaintext attack. In this paper we revisit symmetric pairings on supersingular elliptic curves over large characteristic fields. neous coordinates, one can compute the point doubling 2, This formula has additional optimization tricks, such as division b, modification of the format to reduce the number of additions required for the accumulation in, it is more efficient to compute such terms with a direct multiplication because of, affine coordinates, respectively, one can compute the mixed point addition, Analogously to point doubling, Equation (11.13) is basically the same line evaluation formula.

Moreover, types of monitoring and information systems (police-patrol and fire-alarm governance), and favoritism (social agency relationship) are also included in the framework of investigation. the software implementation, both inside and outside the organization. Springer, Heidelberg, 2014. 459–474. tion of pairings has become an increasingly important research topic. In the context of BN curves, the final exponentiation can be computed through the state-of-the-, by a short sequence of multiplications, conjugations, fast applications of the F, additional algebraic structure allows elements to be compressed and squared consecutively in. %%EOF The main role of a high level implementation plan is to support local or smaller implementation plans. As a final remark, a mixed environment can be presented where there are fixed arguments, and unknown parameters; see Algorithm 11.3 for a version with both fixed and unknown pa-, An important implementation note on the pairing function is that both line functions (Equations, 11.11 and 11.10) expect the parameters of the pairing to be in affine co, based protocols involve either the computation of point additions, or scalar-point multiplications, Jacobian coordinates; however, in the case of the scalar-point multiplication, it is customary, to normalize the point into affine coordinates, but this could be inefficient in the case where, All pairing computations and computations in the related groups eventually break do, finite-field operations to machine instructions of a given target architecture as efficien, considered in this chapter, elements of the finite field have, accomplish this task is to use a software library for “big-in, integer libraries were not originally written for use in cryptograph, the GNU multiprecision library (GMP) has ackno, general-purpose software libraries for finite-field arithmetic hav, and don’t include optimizations for reduction modulo a special-shap, much of an issue in pairing-based cryptograph, shape), but it is a critical disadvantage for non-pairing elliptic-curv, libraries typically optimize separate operations (like addition, subtraction, multiplication) and. The manually extracting of these metadata elements is highly laboraintensive, costly and timeaconsuming for a large document then automated is a key idea to solve the problem but the most existing automated metadata extraction approaches have focused on specific domains and homogeneous documents. access at addresses that depend on secret data. 0000019248 00000 n Below is a diagram that illustrates all of the major steps in a large software implementation project. for instantiating some protocols are proposed in [5]. The key idea of solving the heterogeneity is to classify documents into equivalent groups by using ruleabased approach so that each document group contains similar documents only. bn_write_bin(sk, CRYPTO_SECRETKEYBYTES, k); g2_write_bin(pk, CRYPTO_PUBLICKEYBYTES, pub, COMPRESS); //Input: m - message to sign, mlen - length of message in bytes.
