Abstract

SPECK algorithm is an algorithm that still has a family with lightweight block cipher algorithm. This algorithm was published by the National Security Agency (NSA) in June 2013. This algorithm is used to optimize in a software implementation. This algorithm has 10 block variants, namely block size 32 and key size 64 bits, up to block size 128 and key size 256 bits, selection of the three SPECK type variations following previous research that utilizes the AES algorithm to secure data where AES research has three variation based on the length of a key, AES-128, AES-192 and AES-256. In this study it can be concluded that between the results of encryption and decryption are valid with test vectors, SPECK block size 128 bits and key size 128 bits 1047.6 ms, SPECK block size 128 bits and key size 192 bit 1080.8 ms and SPECK block size 128 bits and key size 256 bits 1114.6 ms. Afterwards the results were put in Kruskal-Wallis and Post Hoc tests to be analyzed and concluded with each change While the results at the time of encryption and decryption of the three algorithms also have significant time differences.

Abstract

Medication safety is a term to describe safety precautions from drug use. Medication safety prevents deaths that were caused by drugs that were prescribed wrongly. One of the main causes of wrongly prescribing a drug is the pharmacist not being able to read a doctor's instruction which is not standardized. Such problems can be overcome by using e-prescription, which can be utilized by doctor's and other medical staff to prescribe and send the prescription. However, there are risks of forgery and denial of the e-prescription. Therefore, a security mechanism needs to be installed on the e-prescription to guarantee integrity, authentication, and non-repudiation, which is in the form of a digital signature. This research will explain the design, implementation, security, and performance of the Android based e-prescription using the Digital Signature Algoritm method and SHA-1 as a hash function. The research results test the integrity aspect using a brute force, collision attack, and birthday attack. However, the integrity aspect could not be fulfilled, because the hash function being used which was SHA-1, was very vulnerable to the previously mentioned attack types. To ensure the authentication and non-repudiation aspect, a test was conducted and both aspects were fulfilled. The process of forming and verifying the signature required 6.36963 ms and 11,79276 ms respectively. The implementation of the digital signature on the e-prescription using DSA in this research was considered a success in the authentication and non-repudiation aspects.

Abstract

QR payment is a payment method by scanning the QR code from mobile application. QR payment requires a security method so that the transaction data cannot be misused or manipulated by certain parties. Cryptography is one of the techniques that can be used to improve data security. One algorithm that can be used is COZMO algorithm. This algorithm is a stream cipher algorithm formed by a combination of Trivium and A5/1. COZMO algorithm is implemented on two Android applications for customer and cashier using the Java programming language and encrypting the transaction data. Based on the input length during the time performance test, 37 characters took 2.05 seconds, 68 characters required 2.06 seconds, while 169 characters took 2.15 seconds. These results indicated that the number of inputs could affect the processing time. A test was conducted over the input length of 68 characters in order to compare the application's performance time before and after implementing the COZMO algorithm which resulting a time difference of 0.3 seconds on the customer's application and 0.4 seconds on the cashier's application. Statistical calculations of the test results showed significant differences after the COZMO algorithm was applied. On the security test, the ciphertext only attack on ciphertexts could not find any plaintext due to the key used was too long. These results showed that COZMO algorithm could be used to secure transaction data.

Abstract

Raspberry Pi 3 is a device that can be used as a middleware. Middleware facilitates communication and information management between heterogeneous components. Based on previous research, there is a security gap in the data transmission system that exposes data packets to an unauthorized party. This problem can be solved with AEGIS algorithm. AEGIS algorithm is a method that guarantees confidentiality and authentication. AEGIS is suitable to be implemented in network communication because it protects packets during transmission. Based on research results, AEGIS algorithm was successfully implemented in MQTT and CoAP protocol's data payload. AEGIS when implemented on the researched system was tested with vector testing and was stated as valid. Time performance test is conducted on middleware systems that either used MQTT or CoAP protocol's, the testing process was time data samples with and without using the AEGIS algorithm. The average results indicated the time difference of a MQTT system that used MQTT system that used AEGIS and without AEGIS was 19.592 milliseconds. Meanwhile, the average of time difference of CoAP system that used AEGIS and without AEGIS was 28.141 milliseconds. The above mentioned results prove that the AEGIS algorithm is capable of securing data confidentiality and authentication on a Raspberry Pi 3.

Abstract

Amazon Web Services (AWS) is one of the cloud computing services which has been primarily used by most of the big industries recently. One of the AWS services which has the advantage to store online data is the Amazon Simple Storage Service (Amazon S3). In this particular service features, there is a data security options, specifically Amazon Client Side Encryption, that works by securing the object and using the key that has been stored by the user in the hand of the client which later would be uploaded to the bucket of the Amazon S3. One of the vital state organization in the United States, National Security Agency (NSA), has launched a cryptography algorithm named SIMON. SIMON Algorithm is a block cipher algorithm that could be applied either in the software or hardware depending to the needs of the users themselves. SIMON Algorithm is applied in the website system by using Python, that is used for encrypting the file which later would be uploaded to the chosen bucket. Based on the result of time performance test, the average speed of both encryption and decryption files are 33.7 seconds and 28.5 seconds. And in the variaton file testing, the result showed that the SIMON algorythm is capable of encrypting files with the extention file: .txt, .docx, .pdf, .png, .jpg, .mp3, .m4a, .mp4 dan .mkv.

Abstract

Authentication is one of many problems about the security of Internet of Things (IoT) devices. Authentication on IoT devices is urgently needed as development on IoT grows. Because IoT devices are constrained devices, a conventional method for authentication is difficult to use. Furthermore, one of the authentication mechanism used in IoT devices called, JSON Web Token (JWT), still has many problems when used on an insecure connection. Zero Knowledge Proof uses the Feige-Fiat-Shamir Identification Scheme protocol which can be used as a solution for problems regarding authentication difficulties on IoT devices. Results from the research show that the system is able to conduct the authentification process using Feige-Fiat-Shamir Identification Scheme protocol with attack resistance limited to keys having an 20 bit length and 20 rounds, a sniffing attack did not result in the compromisation of any confidential data and a brute force attack did not managed to gain the value of modulus n and private key S. Another finding suggests that the amount of rounds has a significant correlation with memory usage of the device and the amount of rounds has an insignificant correlation with the system's execution time.

Abstract

nRF24L01 is a data communication module commonly used on Wireless Sensor Network (WSN) devices. This communication module is often used because of its low power consumption and using little memory. The nRF24L01 module sends data by broadcasting it into an address. To receive data, the nRF24L01 module listen at the same address as well. However, this will create a vulnerability if the device is used to send data only to designated device. Therefore, a solution is needed to secure the data in the module such as implementing the Grain-128 algorithm. Grain-128 algorithm is an encryption algorithm that is designed to be implemented on hardware that requires limited resources. The Grain-128 algorithm is a variant of the Grain algorithm family. Grain-128 algorithm is a stream cipher where this algorithm requires 128 bit key input and 96 bit Initialization Vector (IV). That way, this study uses the Grain-128 algorithm to secure data communication with the nRF24L01 module in terms of confidentiality. Based on testing, the system takes 41363,25 micro seconds to generate keystream. The system also requires 12.02 and 12.26 micro seconds to encrypt and decrypt 8 bit data. The system is vulnerable to active attack but invulnerable to passive attack.
