    This research proposed an improvement of digital signature scheme that have been presented by Chung, Huang, Lai and Chen (CHLC). The security of this scheme is based on the elliptic curve discrete logarithm problem (ECDLP). This scheme requires for signature generation and for signature verification. The improvement of CHLC’s scheme is for the purpose of simplification and also reducing the time complexity for both signature generation and verification. The results obtained from the improvement show that the time complexity for both phases has decreased to and respectively. However, the security analysis for this scheme is the same as what have been shown in the CHLC’s scheme. The estimation of the speed for both signature and verification phase, have showed the improvement is about 96.68% and 50% respectively. Therefore, the proposed digital signature scheme is obviously more eficient and practical to be applied compared with the CHLC’s scheme.

    A fully fuzzy matrix equation of̃ÃX̃B=̃Chas its own important in the application of control systemengineering particularly in the situation of uncertainty. In this study, the equation is solved wherethe triangular fuzzy numbers be the variables of the equation. The algorithm that is used in thesolution is consists of the conversion for the fully fuzzy matrix equation to a fully fuzzy linear systemby utilizing the Kronecker and Vec-operator. Subsequently, the final solution is obtained by usingthe pseudoinverse method. A numerical example and the verification of the solution obtained arepresented to demonstrate the contribution of this study.
