Encrypted Short Message Service Design Using Combination of Modified Advanced Encryption Standard (AES) and Vigenere Cipher Algorithm


 Despite the popularity of social media and Internet-based messaging services, Short Message Service (SMS) is still widely used by a lot of people worldwide. However, in this modern era, Short Message Service (SMS) is not a secure way of sending and receive text messages. Anyone with the right privilleges can easily read all the messages sent using SMS service. Therefore, appropriate cryptographic algorithms should be applied to ensure confidentiality of the message content. In this paper, a modified AES with Vigenere Cipher Algorithm will be used to encrypt the text message, hence greatly increasing the security of the sent messages. Avalanche Effect is chosen as a metric for measuring performance of the proposed algorithm and its implementation. The proposed algorithm shows high Avalanche Effect compared to standard AES algorithm.

Design of an Electric Light Control Device Using Arduino Uno Microcontroller-Based Short Message Service

This study aims to design a tool that can control electric lights remotely. The wastage of using lights often occurs due to the difficulty of the occupants of the house in controlling the lighting, especially when they have to leave the house due to various activities. Lighting needs to be controlled to turn on or not when you want to travel for a long time. In addition, lighting needs to be controlled to significantly reduce the service life of the lamp because it is on continuously. This remote light control system can make it easier for users to cut electricity usage. An electric light controller designed using SMS (Short Message Service) based on the Arduino Uno Microcontroller. This system only applies if the condition of the AC voltage originating from the local PLN is ON. System control is managed using the Atmega328 Arduino Uno Microcontroller. The language used for programming is C/Arduino language, and this tool works on GSM communication systems, especially SMS services. The result of designing this tool is that the user can control (ON/OFF) the lights without being limited by time and place as long as the cellular network is reachable.

Connecting University Students, Faculty and Administrators through an Online SMS Service

King Saud University (KSU) created an online Short Message Service (SMS) called “Tawasul”, developed in house, to connect administrators, faculty, and students. The KSU rector, deans, department heads and program coordinators send group season’s greetings and notifications to the mobile phones of faculty members, staff, and students. Instructors can send course notifications to their students regarding exams and other issues. There are currently 380 SMS groups for department staff, T.A.’s, workshop participants, course enrollees and others. Students and faculty surveyed indicated that the KSU online SMS Service is easy to use. It is faster and more efficient than paper memos and e-mails, especially in emergency situations. It helps conserve paper. Students and faculty can be reached anytime, anywhere and 7 days a week. Unused SMS in the user’s account can be added to his/her balance. SMSs are archived. Those interested to join a group can send a message to the group’s mobile number. Students’ mobile phone numbers are entered manually once and saved as a group. However, some faculty indicated that the allocated 200 free SMSs per month are not enough when class enrollees are more than 50. They also indicated that it is not possible to send a reply, a comment, or a query to the sender of the SMS. Sometimes the service cannot be used when it is under maintenance or when there is a technical problem. It is time-consuming to enter students’ mobile phone numbers manually particularly in large classes. Further results and recommendations are given.

Assessing the challenges to women's access and implementation of text messages for nutrition behaviour change in rural Tanzania.

This process evaluation aimed to understand factors affecting the implementation of a government-sponsored short message service (SMS) programme for delivering nutrition information to rural populations, including message access, acceptability and putting messages into action. The study was nested within a larger randomised controlled trial. Cross-sectional data collection included structured surveys and in-depth interviews. Data were analysed for key trends and themes using Stata and ATLAS.ti software. The study took place in Tanzania's Mtwara region. Surveys were conducted with 205 women and 93 men already enrolled in the randomised controlled trial. A sub-set of 30 women and 14 men participated in the in-depth interviews. Among women relying on a spouse's phone, sharing arrangements impeded regular SMS access; men were commonly away from home, forgot to share SMS or did not share them in women's preferred way. Phone-owning women faced challenges related to charging their phones and defective handsets. Once SMS were delivered, most participants viewed them as trustworthy and comprehensible. However, economic conditions limited the feasibility of applying certain recommendations, such as feeding meat to toddlers. A sub-set of participants concurrently enrolled in an interpersonal counselling (IPC) intervention indicated that the SMS provided reminders of lessons learned during the IPC; yet, the SMS did not help participants contextualise information and overcome the challenges of putting that information into practice. The challenges to accessing and implementing SMS services highlighted here suggest that such platforms may work well as one component of a comprehensive nutrition intervention, yet not as an isolated effort.

Evaluation of Outcomes for HelpSeekers Accessing a Pilot SMS-Based Crisis Intervention Service in Australia.

Background: In July 2018, Lifeline Australia launched Australia's first short message service (SMS) crisis support service. Lifeline Text aims to reduce psychological distress and increase coping and social connectedness among help seekers, particularly those who prefer text-based communication. Aims: We aimed to independently evaluate the pilot SMS service over a 240-day period. Method: The service evaluation used operational data, pre and postconversation automated questions, and an online survey to assess outcomes. Results: There were 7,315 contacts during operational hours, of which 5,266 progressed to the queue and 99.2% were answered. Suicide was actively being considered by 1,554 help seekers, and 171 were assessed at imminent risk. Commonly discussed topics were mental health problems, issues relating to the self and identity, and family relationship difficulties. Limitations: This was an evaluation of a pilot service focusing on demand and short-term outcomes. Conclusion: The service succeeded in reaching some under-served groups. On average, help seekers were significantly less distressed, felt more confident in their ability to cope and felt greater connection to others, following the text intervention. The demand for Lifeline Text and the high level of suicidality of help seekers show it is meeting urgent needs in the community.

Speed Control of AC Motor Using GSM

GSM (SMS) Controlled AC Motor is automatic control system which capable of receiving a set of command instructions in the form of Short message service(SMS) and performs the necessary actions like Start, Stop and speed control. We have used a dedicated modem/mobile at the receiver module i.e. with the model itself and send the commands using SMS service as per the required actions. The GSM modem which is dedicated at the motor driver is interfaced with an intellectual device called Micro controller so that it takes the responsibility of reading the received commands in the form of SMS from the mobile unit and perform the corresponding predefined tasks such as motor start, stop, motor direction and speed control at different levels. The utilization of GSM modem in this project as it ubiquity standard which enables subscribers to use their phones in many parts of the world, and make international roaming very common between mobile phone operators.

Perancangan Aplikasi Penyandian Pesan Teks Menggunakan Vigenere Chiper Dan Algoritma Elgamal

The development of technology and information, especially in the field of information communication, is very rapidly developing, one of them is the communication media of smart phones. one of the facilities provided by smart phones is the exchange of information in the form of sending text messages through Short Message Service (SMS). This information can be in the form of important data that not all parties can find out. Some risks that can threaten message security in SMS services include SMS Spoofing, Snooping SMS and SMS Interception.
 The message security system in the form of text is one of them with a cryptographic system. Cryptography is a message security science that aims to maintain the confidentiality of information contained in data so that information cannot be known by irresponsible parties. Cryptography changes the meaningful writing to be meaningless by using various kinds of cryptographic algorithms. The algorithms used are ElGamal and Vigenere Chiper. The ElGamal algorithm uses 2 different keys in encrypting and decrypting the public key for encryption and the private key for decryption. While Vigenere chipers only use one key that is the same for encryption and description.
 With the text message encoding application using the ElGamal and Vigenere Chiper algorithms, it is expected to help smart phone users with the operating system.

BVPSMS: A Batch Verification Protocol for End-to-End Secure SMS for Mobile Users

Short Message Service ( SMS ) is a widely used communication medium for mobile applications, such as banking, social networking, and e-commerce. Applications of SMS services also include real-time broadcasting messages, such as notification of natural disasters (e.g., bushfires and hurricane) and terrorist attacks, and sharing the current whereabouts to other users, such as notifying urgent business meeting information, transmitting quick information in the battlefield to multiple users, notifying current location to our friends and sharing market information. However, traditional SMS is not designed with security in mind (e.g., messages are not securely sent). It is also possible to extract international mobile subscriber identity of the mobile user. In the literature, there is no known protocol that could enable secure transmission of SMS from one user to multiple users simultaneously. In this paper, we introduce a batch verification authentication and key agreement protocol, BVPSMS , which provides end-to-end message security over an insecure communication channel between different mobile subscribers. Specifically, the proposed protocol securely transmits SMS from one mobile user to many other users simultaneously. The reliability of the protocol is discussed along with an algorithm to detect malicious user requests in a batch. We then evaluate the performance of the proposed protocol in terms of communication and computation overheads, protocol execution time, and batch and re-batch verification times. The impacts of the user mobility, and the time, space and cost complexity analysis are also discussed. We then present a formal security proof of the proposed protocol. To the best of our knowledge, this is the first provably-secure batch verification protocol that delivers end-to-end SMS security using symmetric keys.

The Use of Mobile Apps and SMS Messaging as Physical and Mental Health Interventions: Systematic Review.

BackgroundThe initial introduction of the World Wide Web in 1990 brought around the biggest change in information acquisition. Due to the abundance of devices and ease of access they subsequently allow, the utility of mobile health (mHealth) has never been more endemic. A substantial amount of interactive and psychoeducational apps are readily available to download concerning a wide range of health issues. mHealth has the potential to reduce waiting times for appointments; eradicate the need to meet in person with a clinician, successively diminishing the workload of mental health professionals; be more cost effective to practices; and encourage self-care tactics. Previous research has given valid evidence with empirical studies proving the effectiveness of physical and mental health interventions using mobile apps. Alongside apps, there is evidence to show that receiving short message service (SMS) messages, which entail psychoeducation, medication reminders, and links to useful informative Web pages can also be advantageous to a patient’s mental and physical well-being. Available mHealth apps and SMS services and their ever improving quality necessitates a systematic review in the area in reference to reduction of symptomology, adherence to intervention, and usability.ObjectiveThe aim of this review was to study the efficacy, usability, and feasibility of mobile apps and SMS messages as mHealth interventions for self-guided care.MethodsA systematic literature search was carried out in JMIR, PubMed, PsychINFO, PsychARTICLES, Google Scholar, MEDLINE, and SAGE. The search spanned from January 2008 to January 2017. The primary outcome measures consisted of weight management, (pregnancy) smoking cessation, medication adherence, depression, anxiety and stress. Where possible, adherence, feasibility, and usability outcomes of the apps or SMS services were evaluated. Between-group and within-group effect sizes (Cohen d) for the mHealth intervention method group were determined.ResultsA total of 27 studies, inclusive of 4658 participants were reviewed. The papers included randomized controlled trials (RCTs) (n=19), within-group studies (n=7), and 1 within-group study with qualitative aspect. Studies show improvement in physical health and significant reductions of anxiety, stress, and depression. Within-group and between-group effect sizes ranged from 0.05-3.37 (immediately posttest), 0.05-3.25 (1-month follow-up), 0.08-3.08 (2-month follow-up), 0.00-3.10 (3-month follow-up), and 0.02-0.27 (6-month follow-up). Usability and feasibility of mHealth interventions, where reported, also gave promising, significant results.ConclusionsThe review shows the promising and emerging efficacy of using mobile apps and SMS text messaging as mHealth interventions.

Financial Transaction Security Using Mobile SMS

Almost every business uses SMS for various reasons to increase sales and brand exposure and Mass alert to everyone. 80% of cell phone users carry their phone all the time. Sending a text message to their cell phones is the perfect way to alert them of any urgent information, such as a change of appointment, or product ready for pickup etc. Mass alert are an ideal way for school districts to send alerts to parents regarding school closings, changes in schedules etc. The short message service (SMS) is one of the highly used and well-tried mobile services with global availability within all GSM/CDMA networks. The existing SMS is limited to the transmission of secure plain text between different mobile phone subscribers and server for different purpose. SMS does not have any built-in procedure to authenticate the text and offer security for the text transmitted as data [5], because most of the applications for mobile devices are designed and developed without taking security into consideration [6] [7], But we can use SMS service to protect our financial transaction by enable or disable the account apply some security on SMS. It will help to control fraud on financial traction by ATM or online fund transfer. In this paper detail an overview of SMS transmission and how to apply security on SMS to transfer from one point to another point.

A combined application of lossless and lossy compression in ECG processing and transmission via GSM-based SMS

This paper presents a software-based scheme for reliable and robust Electrocardiogram (ECG) data compression and its efficient transmission using Second Generation (2G) Global System for Mobile Communication (GSM) based Short Message Service (SMS). To achieve a firm lossless compression in high standard deviating QRS complex regions and an acceptable lossy compression in the rest of the signal, two different algorithms have been used. The combined compression module is such that it outputs only American Standard Code for Information Interchange (ASCII) characters and, hence, SMS service is found to be most suitable for transmitting the compressed signal. At the receiving end, the ECG signal is reconstructed using just the reverse algorithm. The module has been tested to all the 12 leads of different types of ECG signals (healthy and abnormal) collected from the PTB Diagnostic ECG Database. The compression algorithm achieves an average compression ratio of ∼22.51, without any major alteration of clinical morphology.

EasySMS: A Protocol for End-to-End Secure Transmission of SMS

Nowadays, short message service (SMS) is being used in many daily life applications, including healthcare monitoring, mobile banking, mobile commerce, and so on. But when we send an SMS from one mobile phone to another, the information contained in the SMS transmit as plain text. Sometimes this information may be confidential like account numbers, passwords, license numbers, and so on, and it is a major drawback to send such information through SMS while the traditional SMS service does not provide encryption to the information before its transmission. In this paper, we propose an efficient and secure protocol called EasySMS, which provides end-to-end secure communication through SMS between end users. The working of the protocol is presented by considering two different scenarios. The analysis of the proposed protocol shows that this protocol is able to prevent various attacks, including SMS disclosure, over the air modification, replay attack, man-in-the-middle attack, and impersonation attack. The EasySMS protocol generates minimum communication and computation overheads as compared with existing SMSSec and PK-SIM protocols. On an average, the EasySMS protocol reduces 51% and 31% of the bandwidth consumption and reduces 62% and 45% of message exchanged during the authentication process in comparison to SMSSec and PK-SIM protocols respectively. Authors claim that EasySMS is the first protocol completely based on the symmetric key cryptography and retain original architecture of cellular network.
