Development of Cryptography-Based Secure Messaging System
Journal of Telecommunications System & Management, 2016
Today data communication is a modern technology that contains a powerful computer processor to exchange information. But brute force attacks are made to break the encryption techniques and these attacks are the main drawbacks of older algorithms. This paper is concerned with the development of a secure messaging system based on cryptographic algorithms that is which is more faster, better immune to attacks, more complex, easy to encrypt and many more advanced security feature included. This project work is designed and developed for a secure messaging both in web and android platforms. The application is well featured and provides encryption/decryption that can protect message from unauthorized access and disclosure over networks. To send message, a recipient or registered user types and encrypts a text message using keyword mono-alphabetic substitution algorithm with a key, selected from key list. The encrypted message is stored in the database and receiver's inbox with serial number of key (not the value). The receiver, after log into his/her own account, selects the key value and then decrypts the encrypted message with the key to see the original message. With compared to other messaging systems, the proposed secure messaging system can be used for chat, messaging, video conferencing and real time file sharing in both web and android platforms.
Mobile Application Design for Protecting the Data in Cloud Using Enhanced Technique of Encryption
International Journal of Engineering & Technology, 2018
This paper provides an enhanced technique for improving the security and protecting the privacy of the cloud computing users by encrypting the data before it reached to server’s storage. Encrypting means the process of converting information or data into unreadable language to prevent unauthorized access. This paper will propose a mobile application design, which will allow the user to encrypt and decrypt the data hence maintaining security and privacy. In the proposed system design, the AES Algorithm will handle the encryption of the data using a keyword which will be defined by the user during the creation of the account. The encryption keyword will be hashed by the system using MD5 Algorithm. The keys will remain in encrypted form, while they are on the server side. Both encrypted data, encryption and decryption keys will be saved on the server in secured form. The idea behind hashing the encryption keys is to protect the keys while they are stored on the server, therefore, any u...

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.
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.
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.

Since mobile phones have become a must-have item, sending messages using text-based messaging or Short Message Service (SMS) through mobile phones becomes something that is almost done every day. A short message is one form of communication services that are already widely used and widely known at this time because it is easy to use and cheap. Utilization of text characters as the media, not only provides ease of use, but also can cause delivery problems of the security of the message content. Another issue is due to the short message using a universal coding standard. Short message has been sent can be captured by the operator or by third parties using a tool that is not expensive. In the message contains the data sender and the recipient's phone number and the content of the message itself. So that short messages can be easily replaced and falsified by third parties. This triggered concerns because sometimes a short message is used to exchange confidential messages. To overcom...
