The Effects of Calcium Excess,water Amount and Mixing Time on the Injectability of Calcium Phosphate Filling Materials
Research Output | Dar Al-hikmah Library | IIUM Only

Variation of calcium excess, water content and mixing time have been taken into the parameters of the injection test of calcium phosphate paste synthesized via low temperature hydrothermal method. The result indicated that all the parameters are very prominent to influence the material injectability possible to be fully injected out the syringe. St

Moim: a Novel Design of Cryptographic Hash Function
Research Output | Dar Al-hikmah Library | IIUM Only

A hash function usually has two main components: a compression function or permutation function and mode of operation. In this paper, we propose a new concrete novel design of a permutation based hash functions called MOIM. MOIM is based on concatenating two parallel fast wide pipe constructions as a mode of operation designed by Nandi and Paul, an

Public Research, Open Science and Innovation: Creating the Path for Sustainable resource-Led Industrialisation in Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

This paper intends to demonstrate the importance of innovation in primary resources by the government research institutes (GRIs) and the practice of open science in creating the path for resource-led and knowledge-intensive industrialisation in Malaysia. The core argument here is that a successful resource -led industrialisation lies on the technol

Protection of the Digital Holy Quran Hash Digest by Using Cryptography Algorithms
Research Output | Dar Al-hikmah Library | IIUM Only

With the rapid technological advances, possibility of tampering information have been increased. Cryptography is the science of information security that includes symmetric encryption and asymmetric encryption which used to avoid the tampering attempts and guarantee the data integrity. This paper discusses a cryptography algorithm (CARCA), which is

Improving Present Lightweight Algorithms
Research Output | Dar Al-hikmah Library | IIUM Only

Lightweight block cipher algorithms are vital for constrained environment. Substitution box (S-box) is the essential constituent of many lightweight block cipher algorithms and it is the only nonlinear part. It is proficient to create confusion in the plaintext during the process of encryption. In this research, a new way of key dependent S-box is

Multicollisions in Sponge Construction
Research Output | Dar Al-hikmah Library | IIUM Only

Cryptographic hash functions take an unfixed size of input and produce a fixed size of an output. A hash function is built using two main components: a compression function and mode of operation. Sponge construction is one of the main operations of modes used in modern cryptographic hash function today. In this paper, we present multicollisions att

A New Fragile Digital Watermarking Technique for a Pdf Digital Holy Quran
Research Output | Dar Al-hikmah Library | IIUM Only

Digital media manipulation has become easily performed at personal level with the rapidly growth of Technology. Presenting an issue of protecting digital media integrity. Watermarking has become a popular solution for copyright and integrity issues. This paper presents an invisible fragile watermarking technique for protecting the integrity of a PD

Improving the Security of Lblock Lightweight Algorithm Using Bit Permutation
Research Output | Dar Al-hikmah Library | IIUM Only

Lightweight block cipher algorithms are important for constrained environment. LBlock uses word permutation to do the diffusion while this research uses bit permutation to increase the number of active Substitution box (S-box). The number of active S-box is a regular method to evaluate the security against linear and differential attacks. The bit p

New Pharmacovigilance Course at the International Islamic University malaysia-Iium
Research Output | Dar Al-hikmah Library | IIUM Only

To the Editor. The Malaysian Adverse Drug Reactions Advisory Committee (MADRAC) was established under the Drug Control Authority (DCA) to perform the function of pharmacovigilance for drugs registered for use in Malaysia. It became a member of the World Health Organization (WHO) Program for International Drug Monitoring in 1990.1 Although MADRAC ha

Investigation of Solvent System for the Production of Biodiesel from Sludge Palm Oil (Spo) by Enzymatic Transesterification
Research Output | Dar Al-hikmah Library | IIUM Only

Sludge palm oil (SPO) was used to produce biodiesel by direct enzymatic transesterification using locally produced Candida cylindracea lipases from palm oil mill effluent (POME). The solvent system was investigated by comparing the effect of methanol and ethanol. The yield of biodiesel and conversion of free fatty acids (FFAs) into biodiesel for et
