Abstract

Communication is one of the basic human traits that are useful for interacting with each other. One of the methods of communication used by humans is text or writing which serves to convey messages to the recipient. The message can contain information that is confidential and is likely to be intercepted by parties who are not responsible for knowing the contents of the message and changing it before it reaches the recipient. Therefore text security is important to maintain the confidentiality of the information in the message. With the Hybrid Cryptosystem method with the RSA-CRT algorithm (asymmetric algorithm) and the One Time Pad algorithm (symmetric algorithm) a software will be produced to increase security in text messages that encrypt/decrypt messages with session-key One Time Pad generate various character messages. which are coded as symbols that are difficult for cybercriminals to know and are secured with an RSA-CRT public key in the form of numbers that are difficult to know so as to increase the level of message key security. Komunikasi adalah salah satu sifat dasar manusia yang gunanya untuk berinteraksi satu sama lain. Salah satu metode berkomunikasi yang digunakan manusia ialah teks atau tulisan yang berfungsi untuk menyampaikan pesan kepada penerimanya. Pesan tersebut dapat berisi suatu informasi yang bersifat rahasia dan besar kemungkinan disadap oleh pihak-pihak yang tidak bertanggung jawab untuk mengetahui isi pesan tesebut dan merubahnya sebelum sampai kepenerimanya. Maka dari itu pengamanan teks merupakan hal penting untuk menjaga kerahasiaan informasi pada pesan tersebut. Dengan metode Hybrid Cryptosystem dengan algoritma RSA-CRT (algoritma asimetris) dan algoritma One Time Pad (algoritma simetris) akan dihasilkan sebuah perangkat lunak untuk meningkatkan keamanan pada pesan teks yang membuat enkripsi/dekripsi pesan dengan session-key One Time Pad menghasilkan berbagai pesan karakter yang bersandi seperti simbol yang sulit untuk diketahui cybercriminal dan diamankan dengan kunci public RSA-CRT dalam bentuk angka yang sulit diketahui sehingga mampu meningkatkan tingkat keamanan kunci pesan.
