New Symmetric Key Cryptographic Algorithm Using Combined Bit Manipulation and MSA Encryption Algorithm: NJJSAA Symmetric Key Algorithm

The main objective of the study conducted in this article is to introduce a new algorithm of encryption and decryption of a sensitive message after transforming it into a binary message. Our proposed encryption algorithm is based on the study of a particular graph constructed algebraically from the quadratic residues. We have exploited the Paley graph to introduce an abstract way of encryption of such message bit according to the other message bits by the intermidiate study of the neighborhood of a graph vertex. The strong regularity of the Paley graphs and the unknown behavior of the quadratic residues will play a very important role in the cryptanalysis part which allows to say that the brute force attack remains for the moment the only way to obtain the set of possible messages.

Rapid development of digital image technology secret causes images require security aspect. Reviews These digital secret image can be encrypted using cryptographic methods. After being encrypted, the image is randomized, so that if it is Obtained by an unauthorized party, the image has no meaning. The cryptographic algorithm used in this study is Gifford method. The Gifford method is a stream cipher, a symmetry encryption algorithm that transforms the data character by character. Gifford has 8 registers filled with key bits. The processes performed by the Gifford method are the Output Function process, the 1-bit Sticky Shift Right process, the 1-bit Left Shift process, the XOR operation and the shift register operation to the right. The decryption process must use the same key as the encryption process in order to Obtain the original image.

Internet Network

The internet network is growing rapidly and has a great impact on human life. The development of the internet network has enabled many people to exchange information or messages,one of tham by using email media. Apparently the internet is a path that in ni not too safe because it is a common communication media that can be used by everyone so prone to tapping information or messages. Therefore, security and confidentiality are needed in data communications. One may to keep messages safe is to use steganography technique. The steganography method used is the method of message insertion using BPCS (Bit Plane Complexity Segmentation). Before the message is inserted, the message is first encrypted using cryptography techniques. The cryptographic algorithm used is RSA algorithm. RSA algorithm consists of encryption algorithm and decryption algorithm. The confidential message is encrypted using RSA encryption algorithm and inserted using the insertion method of BPCS. With the technique of steganography on the image media then the delivery of a secret message will have a good level of security because it can not be detected directly by the senses of human vision. Keywords: cryptography, steganography, RSA, method BPCS Abstrak Jaringan internet berkembang dengan pesat dan memberikan pengaruh besar bagi kehidupan manusia. Perkembangan jaringan Internet telah memungkinkan banyak orang untuk saling bertukar informasi atau pesan salah satunya dengan media email. Ternyata, internet merupakan jalur yang tidak terlalu aman karna merupakan media komunikasi umum yang dapat digunakan semua orang sehingga rawan penyadapan informasi atau pesan. Oleh karena itu, keamanan dan kerahasiaan sangat dibutuhkan dalam komunikasi data. Salah satu cara untuk menjaga keamanan pesan adalah menggunakan teknik steganografi. Metode steganografi yang digunakan adalah metode penyisipan pesan, dengan menggunakan metode BPCS (Bit Plane Complexity Segmentation). Sebelum pesan disisipkan terlebih dahulu pesan tersebut dienkripsi dengan menggunakan teknik kriptografi. Algoritma kriptografi yang digunakan adalah algoritma RSA. Algoritma RSA terdiri dari algoritma enkripsi dan algoritma dekripsi. Pesan rahasia disandikan menggunakan algoritma enkripsi RSA dan disisipkan menggunakan metode penyisipan BPCS. Dengan adanya teknik steganografi pada media citra maka pengiriman suatu pesan yang bersifat rahasia akan memiliki tingkat keamanan yang baik karena tidak dapat dideteksi langsung oleh indera penglihatan manusia.
