SMS SECURITY SYSTEM USING ENCRYPTION TECHNIQUES

2012

Nowadays, security of SMS is a crucial aspect because it plays an important role in value added services and mobile commerce. Asymmetric algorithm like Diffie-Hellman can be used to encrypt the SMS message in M-commerce or mobile banking system. We use authentication functions to maintain the integrity of data. Password key exchange protocol based on Diffie-Hellman algorithm generates a secret shared key which can be used in message encryption and in MAC function. MAC (message authentication code) or hash functions are used maintain the integrity of message and can be used with the encryption. These functions also act as an error detecting code or checksum. This paper discusses the comparative analysis of both the authentication functions separately for password key exchange protocol by analyzing some of the security issues. The discussion of this paper concludes that MAC functions are more secure than hash function, but having greater complexity and take more to execute. So, it's better to use hash function for maintaining the integrity of message over a network where the transmitted amount of message is very small (SMS). Here, digital signature is generated with RSA to show the functionality of MD5 and SHA1, which prevents SMS from message modification and non-repudiation attack.

Short Message Service (SMS) has become common in many of our daily life applications. Sometimes SMS is used to send confidential information like password, passcode, banking details etc. But in traditional SMS service, information content is transmitted as plain text which is not at all secure. It’s because when SMS is transmitted as plain text without using any encryption mechanisms it is easily subjected to many attacks. In this paper, we propose a protocol called SecuredSMS which make use of the symmetric key shared between the end users thus providing secure and safe communication between two users. The analysis of this protocol shows that it is highly secure as it is able to prevent the information content from various attacks like replay attack, man-in-the-middle attack, over the air modification and impersonation attack. SecuredSMS can be activated in the phone using PIN number. It also provides a way for remote destruction and remote locking in the case if the phone is stolen or lost.

SMS (Short Message Service) is used because it is cheap, easily accessible and a popular method to sent information by a text message using a mobile phone. However, the original SMS application on android phones are have no security features. A message sent is still in plain text form so easily be intercepted without unknown by the sender or the recipient. Therefore, proposed encryption algorithm RSA (Rivest Shamir Adleman) and Caesar Cipher to secure a text message sent. The results showed that the application can prevents the contents of SMS to intercepted or viewed by unauthorized people because the message that is sent is not in plain text, but the message has been encrypted (cipher text).

The Short Message Service (SMS) is one of very popular kind of superior and well-tried services with a global availability in GSM networks. This paper deals with an SMS security for mobile communication. The transmission of an SMS in GSM network is not secure; therefore it is desirable to secure SMS by additional encryption. A proposed approach, based on encryption and digital signature efficiently embeds the confidentiality, integrity, authentication, and non-repudiation in the SMS messages. In the next part, there is the description of design and implementation of the application, which encrypts SMS by DES, Triple DES, AES and Blowfish algorithms and finally signs SMS by DSA or RSA algorithm respectively. At the end, we described attacks on secured SMS and future extension of the application.

The rapid development of communication technology, on the one hand, is bringing many technological conveniences with it and simplifying our lives. On the other hand, it has disadvantages on hiding the information that is continuously roaming through various communication media resources between senders and receivers and on not sharing them with third people.

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.

Short Message Service (SMS) has grown in popularity over the years and it has become a common way of communication. SMS is usually used to transport unclassified information, but with the rise of mobile commerce it has become a popular tool for transmitting sensitive information between the business and its clients. By default SMS does not guarantee confidentiality and integrity to the message content. Therefore SMS is not totally secure and reliable. This affects the Wireless Messaging API (WMA)-an optional package for Java 2 Micro Edition that enables SMS messaging on Java-enabled cellular phones. This paper proposes a protocol that can be used to secure a SMS connection between a WMA client and SMS-based server.

In the past few years a new generation of mobile messaging systems have been developed in conjunction with the explosive growth in the use of smart phones. As this technology enabling for accessing Internet based services, the new-generation the messaging applications was directed to play the role of traditional text messaging(SMS). Such applications require only the user’s phone number for registration. Unfortunately, these appl1icationsdo not provide a built-in support for any security feature. Sometime, the basic security features (e.g., authentication and confidentiality between the communicators) must be ensured in messaging service. In addition to that, most of the modern communications via internet takes place "through the air"; therefore the risk of interception becomes greater than in case of wired networks. If the message is not encrypted, or encrypted using a weak algorithm, the attacker can get it and may make hard harm. This paper presents a security solution to ensure confidentiality and authentication of exchanged messages, the users of proposed system can communicate exclusively via web server and by using a dedicated android application. The exchanged messages are encrypted using stream cipher RC4 with a personalP2P dynamic encryption key.
