Research ArticleOpen accessIn the author namesA New Digital Signature Scheme Based on Factoring and Discrete LogarithmsE.S. Ismail, N.M.F. Tahat, R.R. AhmadProblem statement: A digital signature scheme allows one to sign an electronic message and later the produced signature can be validated by the owner of the message or by any verifier. Most of the existing digital signature schemes were developed based on a single hard problem like factoring, discrete logarithm, residuosity or elliptic curve discrete logarithm problems. Although these schemes … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the author namesSelected Malaysian Wood CO2 -Laser Cutting Parameters And Cut QualityNukman Yusoff, Saiful Rizal Ismail, Azuddin Mamat, Aznijar Ahmad-YazidLaser has been used to cut most non-metallic materials very efficiently and successfully because these materials are highly absorptive by the CO2 laser wavelength of 10.6 10.6µm. Laser cutting process has been found to be reliable in loads of applications, with several advantages over other mechanical means in producing successful cut of even thermally sensitive materials such as wood.
