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.

Subject Review: SMS Encryption for Android Mobile using the Encryption Algorithm

Due to the constant attack on network communications and mobile networks by hackers and the few security means of communication networks, a proposal to encrypt voice calls had to be developed. This proposal encrypts voice calls before they reach the phone and decrypts them when they are out of the phone at the receiver. The idea is to encrypt audio data without using servers or intermediary systems between the telephone device and the networks. CryptoBin encryption algorithm is used to encrypt and decrypt the audio data, which are characterized as a new and unknown algorithm, and characterized by speed and strength in encryption. This algorithm uses two secret keys to increase the strength of encryption and security.

Encryption Of Voice Calls Using CryptoBin Algorithm

With rapid evaluation of technologies, huge amount of critical information can exchange over unsecure network every day, secure and fast encryption schemes become more and more urgent need to provide the desirable confidentiality and thwart unauthorized access, lately and for many reasons, chaotic based encryption algorithms become more and more popular technique due to exceptionally superior characteristics such as simplicity, resistance attacks and high speed, in this paper the advantages of two nonlinear hyper-chaotic systems will utilized to strength the  proposed encryption algorithm, the random sequences generated from systems will used to position scramble and value change of the plaintext, the main features of such method are efficiency, large key space, low computational overhead, and simple design as well as the experimental results demonstrate that the proposed method have more ability to thwart attacks.

Text Encryption Method Using multi Hyperchaotic systems

Encryption is process of turning a plaintext to jargon or the method of changing confidential file to jargon in order prevent unauthorized persons to gain access to confidential message. Message is the transfer of information from the sender to the receiver through a particular medium. Encryption is the most effective process for achieving data security. The process of Encryption hides the contents of a message in a way that the original information is recovered only through a decryption process. This paper presents an Encryption/Decryption application of messages on both java and Android phones. The method of encryption of message in this paper is AES (Advance Encryption System) where the same key that is used to encrypt is used to decrypt. The Encryption key is entered into the mobile phone text field by the user. The same encryption key is also used to decrypt the encrypted binary file.
