In the process of treating uncertainties of fuzziness and randomness in real regression application, fuzzy random regression was introduced to address the limitation of classical regression which can only fit precise data. However, there is no systematic procedure to identify randomness by means of probability theories. Besides, the existing model mostly concerned in fuzzy equation without considering the discussion on probability equation though random plays a pivotal role in fuzzy random regression model. Hence, this paper proposed a systematic procedure of Naïve Bayes to estimate the probabilities value to overcome randomness. From the result, it shows that the accuracy of Naïve Bayes model can be improved by considering the probability estimation.

Security models have been developed over time to examine the security of two-party authenticated key exchange protocols. In 2007, a reasonably strong security model for key exchange protocols has been proposed, namely extended Canetti-Krawczyk model (eCK model), addressing wide range of real-world attack scenarios. They constructed a protocol called NAXOS, that is proven secure in the eCK model. In order to satisfy the eCK security, NAXOS protocol uses a hash function to combine the ephemeral key with the long-term secret key, which is often called as “NAXOS trick”. However, for the NAXOS trick based protocols, the way of leakage modelled in the eCK model leads to an unnatural assumption of leak-free computation of the hash function. In 2015, Alawatugoda, Stebila and Boyd presented a secure and NAXOS trick key exchange protocol, namely protocol P1. In this work, we implement the protocol P1 to be used with the widely-used OpenSSL cryptographic library. OpenSSL implementations are widely used with the real-world security protocol suites, particularly Security Socket Layer and Transport Layer Security. According to our knowledge, this is the first implementation of an eCK-secure protocol for the OpenSSL library. Thus, we open up the direction to use the recent advancements of cryptography for real-world Internet communication.

Current electronic voting protocol require a centralized system to control the whole procedure from ballot inputs to result outputs and election monitoring. Meanwhile, blockchain technology provide a decentralized system which open across the whole network of untrusted participants. Applying blockchain technology into electronic voting protocol through a proper architecture can instil characteristic such as data confidentiality, data integrity and data authenticity. In this paper, we going to discuss a proposed method on how to leverage the advantages from blockchain into electronic voting protocol. This blockchain-based electronic voting protocol promise to provide a secure electronic election process given the proposed system works. We implement a protocol using blockchain to turn election protocol into an automated control system without relying any single point of entity. Lastly, we discuss the characteristics of our proposed blockchain-based electronic voting protocol in this paper. However, there are also emerging challenges and limitations awaiting to overcome. This paper gives a comprehensive overview of our proposed protocol.

Cryptography known as art and science which is used to hide the messages that contain a few policy terminologies. These terminologies in cryptography are plaintext/ messages, ciphertext, encryption, decryption and key. Encryption is a proses to transform the plaintext together with key into ciphertext. Decryption is the reverse process of encryption. Caesar cipher and transposition cipher are two historical ciphers in cryptography. Caesar cipher is a monoalphabetic cipher. It is a substitution cipher which replace each letter in plaintext with another letter to form the ciphertext. Transposition cipher uses a technique which rearrangement letters in plaintext with a keyword and produce the ciphertext. Caesar cipher and Tansposition cipher both are commonly used to encrypt the English letters. The output of encrypted of English letters are known as ciphertext. The attacker can easily cryptanalysed the Caesar cipher by observing the frequency distribution English letters and ciphertext. For Transposition cipher, the cipher can be cracked by knowing the keyword. To date, there is no any research encrypt Jawi letters using Caesar cipher and Transposition cipher. Hence, in this paper encryption and decryption by using Caesar cipher and Transposition cipher in Jawi messages are proposed. Next, the security level of Caesar cipher and Transposition cipher in Jawi messages are compared. The result has shown that both ciphers are still not secure to protect the confidentiality of the Jawi messages.

Internet of Things (IoTs) are internet computing devices which are connected to everyday objects that can receive and transmit data intelligently. IoTs allow human to interact and control everyday objects wirelessly to provide more convenience in their lifestyle. The Raspberry Pi is a small, lightweight and cheap single board computer that can fit on human’s palm. Security plays a big role in a home. People concern about security by preventing any intruders to enter their home. This is to prevent loss of privacy and assets. The closed-circuit television (CCTV) is one of the device used to monitor the secured area for any intruders. The use of traditional CCTV to monitor the secured area have three limitations, which are requiring a huge volume of storage to store all the videos regardless there are intruders or not, does not notify the users immediately when there are motions detected, and users must always check the CCTV recorded videos regularly to identity any intruders. Therefore, a smart surveillance monitoring system is proposed to solve this problem by detecting intruders and capturing image of the intruder. Notifications will also be sent to the user immediately when motions are detected. This smart surveillance monitoring system only store the images of the intruders that triggered the motion sensor, making this system uses significantly less storage space. The proposed Raspberry Pi is connected with a passive infrared (PIR) motion sensor, a webcam and internet connection, the whole device can be configured to carry out the surveillance tasks. The objectives of this project are to design, implement and test the surveillance system using the Raspberry Pi. This proposed surveillance system provides the user with live stream of video feed for the user. Whenever a motion is detected by the PIR motion sensor, the web camera may capture an image of the intruder and alert the users (owners) through Short Message Service (SMS) and email notifications. The methodolo

Attendance system University Tun Hussien Onn Malaysia is the system to record, and monitor the staff attendance to the daily work. This project is to design develop and implement attendance system using radio frequency identification technology. This technology is divided into two types which are system passive and system active. The proposed system used the system passive to record staff attendance. Frequency identification technology will read the staffs tag and the attendance are recorded automatically and store it in database. The proposed system has several securities feature that can prevent security breaches which is captcha and audit trail. The advantage of proposed system is can differentiate between the human input and robot input and record all the user activity when access to the system.

Management system is the framework of processes and procedures used to ensure that an organization can fulfil all task required to achieve its objectives. In recent times, most organization will opt to use management system in their daily business task. There are those who still use the non-computerized system as opposed to the computerized management system. The noncomputerized system may be effective but it also causes greater task load when implemented. Computerized system makes it easier for users with functions such as searching, automatic calculation, and display of related information with minimal queries. The development of Shears Inc. Salon Management System is to act an alternative to the non-computerized system implemented by Shears Inc. Salon. The system developed will be able to decrease the task load of owner and employees of Shears Inc. Salon. Software Development Life Cycle methodology is used in the development of Shears Inc. Salon Management System. This system is installed in computer device. It runs on local host server and MySQL is used as the database server. The programming language used in developing Shears Inc. Salon Management System is PHP programming language. Hence, Shears Inc. Salon Management System is an alternative for the salon to manage recording tasks.

Video steganography is about hiding the secret message into the video as the cover media. Steganography is a technique use to secure the transmission of secret information or hide their existence. Most of the steganography software such as DeEgger Embedder and OurSecret does not have encryption algorithm to preserve the confidentiality for the secret message. OurSecret software only using simple password to keep the secrecy of the message. A simple password is not strong enough to protect the secret message, secret message will be vulnerable once the attacker successfully attack the steganography technique use to hide the secret message in the video. Furthermore, password is not an encryption algorithm. Secret message without encrypted is the vulnerability to the secret message. Confidentiality of the secret message will not be able to preserve. Hence there is a need to encrypt the secret message with stream cipher while not leaving it vulnerable to attacker. Stream cipher provide bit by bit encryption. A video steganography with embedding text with RC4 encryption cipher is design, develop and test in this project

A key derivation function (KDF) is a function that transforms secret non-uniformly random source material together with some public strings into one or more cryptographic keys. These cryptographic keys are used with a cryptographic algorithm for protecting electronic data during both transmission over insecure channels and storage. In this thesis, we propose a new method for constructing a generic stream cipher based key derivation function. We show that our proposed key derivation function based on stream ciphers is secure if the under-lying stream cipher is secure. We simulate instances of this stream cipher based key derivation function using three eStream nalist: Trivium, Sosemanuk and Rabbit. The simulation results show these stream cipher based key derivation functions offer efficiency advantages over the more commonly used key derivation functions based on block ciphers and hash functions.

Cryptographic hash functions are very common and important cryptographic primitives. They are commonly used for data integrity checking and data authentication. Their architecture is based on the Merkle-Damgard construction, which takes in a variablelength input and produces a fixed-length hash value. The basic Merkle-Damgard construction runs over the input sequentially, which can lead to problems when the input size is large since the computation time increases linearly. Therefore, an alternative architecture which can reduce the computation time is needed, especially in today's world where multi-core processors and multithreaded programming are common. An Omega Network Hash Construction that can run parallel on multi-core machine has been proposed as alternative hash function's construction. The Omega Network Hash Construction performs better than the Merkle-Damgard construction, and its permutation architecture shows that its security level in term of producing randomness digest value is better than Merkle-Damgard construction.
