SMS SECURITY SYSTEM USING ENCRYPTION TECHNIQUES
IJCSMC, 2019
Communication has been a major factor in human’s everyday life. The advancement of information technology changed the method of online transactions. No one uses SMSs that frequently to pass messages from one to another because of the arrival of the free data services and cheap data packs from the ISPs. But SMS still plays a very vital role in our day to day lives and its theft is increasing concerns to secure it. No airline or bank or subscription services send their transaction details through any web appl ication but through SMS. SMS plays an important role in online transactions .With the increasing use of SMS for communication and information exchange, care should be taken when sensitive information is transmitted using SMS. Users should be aware that SMS messages might be subject to interception. Solutions such as encrypted SMS should be considered if there is a need to send sensitive information via SMS. The messages are encrypted by strong cryptographic algorithms. The encrypted message received by the customer decrypt the message by authentication. This is only known to user. It uses RSA algorithm for secure keys and AES algorithm to secure message. Authentication is implemented by using pattern lock. This system provide secure and reliable communication environment.
Review on SMS Encryption of Android Mobile by Using Cryptography Algorithm
International Journal of Engineering Research and Advanced Technology (IJERAT), 2019
Nowadays, SMS or messaging is a very common way of communication. So, it differs from the apps and instant messaging available but SMS is still one of the broad communication methods as it does not require internet connection and sending inexpensive, fast and modest SMS messages. When confidential information is replaced by SMS, it is difficult to protect information from secure SMS and ensure that the message is sent only by approved senders. This research reviews and describes several methods used to encrypt SMS massage on android based on the encryption algorithm and compare these methods.
Study on the Effectiveness of Securing Instant Messaging Using One Time Pad
2014
Instant Messaging (IM) is one of the popular applications for real-time communication. Along with its popularity the threats that target instant messaging also rising. Some studies have been conducted to improve the message confidentiality of the instant messaging, which do not possess by most existing IM. The purpose of this study is tried to verify the effectiveness of applying One Time Pad (OTP) encryption in the instant messaging system. This scheme is to address the weakness IM of transferring message in plaintext. Experiment was done on the proposed system to find out the performance. Results were compared against same IM system without encryption and also against similar system Results showed that there is probability to equip IM system with OTP encryption to secure the message transmission without decrease its performance.
Developing a Secure Messaging Platform in Mobile SMS Using Advanced Encryption Standard Concept
2014
Billions of text messages are sent daily through GSM networks sent in plain text format which makes them susceptible to various attacks. With the increasing number of software crackers available for free in the internet, studies have shown SMS continues to suffer from several security vulnerabilities and loopholes. The aim of this project was to develop a secure messaging platform for Java enabled phones to securely send encrypted short messages via the GSM network.. The application was developed in MDIP 2.0 and CDLC 1.1configurations and applied symmetric encryption concepts. The experimental results revealed that the mobile application was able to encrypt, decrypt, send and receive text messages without adding changing the size of the packets .
One Time Pad (OTP) is a cryptographic algorithm that is quite easy to be implemented. This algorithm works by converting plaintext and key into decimal then converting into binary number and calculating Exclusive-OR logic. In this paper, the authors try to make the comparison of OTP cryptography using KPI and KCT so that the ciphertext will be generated more difficult to be known. In the Key and Plaintext Insertion (KPI) Method, we modify the OTP algorithm by adding the key insertion in the plaintext that has been splitted. Meanwhile in the Key Coloumnar Transposition (KCT) Method, we modify the OTP algorithm by dividing the key into some parts in matrix of rows and coloumns. Implementation of the algorithms using PHP programming language.
The development of telecommunications technology is so rapid has given such great benefits. With the telecommunication technology, distance and time no longer be a significant obstacle. One of the results of telecommunications technology that is well known is the Short Message Service. In this study developed an application on the mobile phone to modify the SMS message into ciphertext so that the information content of the SMS is not known by others. SMS delivery system for encrypting messages into ciphertext using a key that is entered by the sender then sends to the destination number. SMS reception system to decrypt it to others via SMS without the fear of information from these messages will be known by others. The method used in the system encrypt and decrypt the message is the algorithm Tiny Encryption Algorithm and implemented using the Java programming language. JDK 1.7 as the Java programming language ciphertext into plaintext using the key entered by the receiver and displays the original message to the recipient. This application can be used by someone who wants to send a confidential information and the Java compiler. Eclipse, a Java SDK and the Android SDK as a Java source code editor.
END TO END TRANSMISSION OF SMS USING CRYPTOGRAPHY TECHNIQUE
Short message service (SMS) is a very popular and one of the easy to use communication technologies for mobile phone devices. Originally, this service was not designed to transmit secured data, so the security was not an important issue during its design. Short Message Service is normally used to transport unclassified data, but with the rise of mobile commerce it has become a fundamental tool for conducting business. However SMS does not guarantee confidentiality and integrity of the message. Now a days, short message service (SMS) is being us ed in many daily life applications, including mobile banking, mobile commerce, and so on. But when we send an SMS from one mobile device 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 propos e an efficient and secure technique, which provides end - to - end secure communication through SMS between end users. This paper proposes encryption technique that can be used to secure a SMS communication, when SMS is transmitting form source to destination, it have to be reached up to the destination securely means SMS transmission have to be secure.
