Abstract-At present, SMS or messages are a very common way of communication. So it's different from the applications and instant messaging available but SMS is still one of the widespread ways of communication because it does not require an Internet connection and send SMS messages are Inexpensive, fast and modest. When secret information is replacement using SMS, it so hard to protect information from SMS safe and it ensures that the message is sent only by authorized senders.This research describes a solution which provides (SMS) safely and ensures the provision of secrecy, authentication. We have used the public-key cryptosystems (RSA) along with chaotic algorithm for encryption and data decryption. RSA also provides strong encryption but the secret increment when using chaotic algorithm is a well method for encryption message,the combination of chaotic theory and cryptography forms an important field of information security. This method was implemented in mobile environment with android operating system .The system was implemented using the JAVA language and the proposed method was tested in various types of operators (such as the S3, Galaxy S7, Galaxy j7, Huawei Nova2 plus, HTC).

“…Target signal extraction in the context of chaotic noise has been a popular research area. Fei [2] studied an image encryption algorithm based on mixed chaotic dynamic systems and external keys. Uchida [3] used two microchip solid-state lasers with external modulation as chaotic signal sources and the simulation results showed that algorithm gived a good performance in the separation and denoising of mixed noisy signals in the presence of a white Gaussian noise or stationary colored noise, when analysis based on the second-order statistics was applicable [4].…”

High Frequency Surface Wave Radar holds significant potential in sea detection.However, the target signals are often surpassed by substantial sea clutter and ionospheric clutter, making it crucial to address clutter suppression and extract weak target signals amidst the strong noise background.This study proposes a novel method for separating weak harmonic target signals based on local tangent space, leveraging the chaotic feature of ionospheric clutter.The effectiveness of this approach is demonstrated through the analysis of measured data, thereby validating its practicality and potential for real-world applications.
