Security is very important in all aspects to protect data. Text messages on mobile phones, which is sms (short messages service) is one of theimportant data that needs a data security system. Data security is used to maintain the confidentiality of important data that we have on mobile devices.The encryption process is used so that messages cannot be read by other unwanted parties. While the decryption process is used so that the messagecan be read back by the intended party. Rivest Cryptography, Shamir, Adleman (RSA) is one of the asymmetric cryptographic algorithms that use a keypair, that is the public key and private key. The key length can be set, where the longer the key formation bit, the harder it is to solve because it is difficultto factor two very large numbers. This study applies the Rivest, Shamir, Adleman (RSA) algorithm for text message security applications based onAndroid. Based on the research that has been done, the author can draw conclusions, namely: Rivest, Shamir, Adleman (RSA) cryptographic algorithmcan be implemented for text message security Android based. So it is safer to exchange text messages (SMS) so that user privacy is guaranteed

Abstract - Cryptography is an art and science to maintain data security. In maintaining the security of cryptographic data transforming clear data (plaintext) into a password (ciphertext) that cannot be recognized. This ciphertext is then sent by the sender to the recipient. After arriving at the recipient, the ciphertext is transformed back into a plaintext form so that it can be recognized. The method used is the encryption method asymmetrical Rivest Shamir Adleman (RSA). The security of the RSA algorithm lies in the difficulty of factoring large numbers into prime factors. Factoring is done to obtain a private key. Making this application using the PHP programming language. The final result is a desktop-based application that can be used to encrypt text files. This application can be used as a way to secure data, because only authorized people can view encrypted data. Keywords - Cryptography, RSA, Encryption - Decryption, Text, PHP

Encryption And Decryption

In this paper two methods are used, namely the vigenere cipher method and the RSA method. The vigenere cipher method is an example of a symmetric algorithm, while RSA is an example of an asymmetric algorithm. The combination of these two methods is called hybrid cryptography which has the advantage in terms of speed during the encryption process. Each process, which is encryption and decryption, is carried out twice, so that security can be ensured. In the process of forming the key used the RSA method. In the encryption process using public keys that have been generated before when the key is formed. This public key is used in sending data to the recipient of a secret message where this key is used for the data encryption process. The Secret key is kept and will be used during the decryption process. There is a system architecture that describes how clients and servers communicate with each other over the internet using the TCP protocol where the client here is an IoT device and the server is a server.

ABSTRACTIt is now commonplace that secrecy must be truly enhanced and tightened as it weighs the emergence of the latest technology that is growing rapidly. Of course an agency, group, or individual have data that is confidential and do not want to be known by other parties hence the need for a system capable of securing the data. For this reason this research aims to create Cryptography application by applying a combination of Hill Cipher and RSA algorithm, Cryptography is also called coding language and I apply Hill Cipher because it is a classical method that uses multiplication for each encoded character while RSA is a modern method that has 2 keys ie key public and secret key where the public key is used for encryption and secret key to retranslate the original form. By applying a combination of classical and modern methods it can be more secure so it is more difficult to be solved by unwanted parties.Keyword : Data Security, Cryptography, Hill Cipher, RSAABSTRAKDi masa sekarang sudah menjadi hal yang biasa bahwa kerahasiaan harus benar – benar ditingkatkan dan diperketat karena menimbang kemunculan teknologi terbaru yang semakin pesat berkembang. Tentu sebuah Instansi, kelompok, ataupun individu memiliki data yang bersifat rahasia dan tidak ingin diketahui oleh pihak lain maka dari itu diperlukannya system yang mampu mengamankan data tersebut. Untuk itulah penelitian ini bertujuan membuat aplikasi Kriptografi dengan menerapkan kombinasi Algoritma Hill Cipher dan RSA, Kriptografi juga disebut bahasa persandian dan saya menerapkan Hill Cipher karena merupakan metode klasik yang menggunakan perkalian untuk tiap karakter yang disandikan sedangkan RSA adalah metode modern yang memiliki 2 kunci yaitu kunci publik dan kunci rahasia dimana kunci publik digunakan untuk penyandian dan kunci rahasia untuk menterjemahkan kembali k bentuk asli. Dengan menerapkan kombinasi metode klasik dan modern ini dapat lebih mengamankan sehingga lebih sulit untuk dapat di pecahkan oleh pihak – pihak yang tidak diinginkan.Kata Kunci : Pengamanan Data, Kriptografi, Hill Cipher, RSA.

Abstract:Computer data security relies on preventing data theft from irresponsible parties by using cryptography method. Some cryptography algorithms have good and poor performance in encrypting and decrypting data depending on the key types. Therefore the purpose of this research is to measure the performance of the hybrid algorithm, consisting a symmetric keyBlowfish algorithm and an asymmetric key RSA algorithm, in encrypting and decrypting multiple types of data such as documents, photos, audios, and videos. The result is the performance of the hybrid algorithm is almost on par with Blowfish and provides a more secure data encryption and decryption by taking advantage of RSA algorithm. The average encryption performance of hybrid algorithm is 0.85s on document, 1.06s on photo, 3.38s on audio, and 15.56s on video. While the average decryption performance of hybrid algorithm is 1.01s on document, 1.38s on photo, 4.3s on audio, and 27.56s on video.            Keywords:Hybrid cryptography, Data security, Performance, Blowfish, RSA  Abstrak:Keamanan data komputer berhubungan dengan pencegahan dari pencurian data oleh pihak yang tidak bertanggung jawab, salah satu cara pengamanan data komputer yaitu dengan teknik kriptografi.
