“…Hill Cipher is a polyaphabetic cipher that is categorized as a block cipher, because the text to be processed will be divided into blocks of a certain size. Each character in one block will affect the other characters in the encryption and decryption process, so that the same character is not mapped to be the same character as well [13]. Hill Cipher includes classic cryptographic algorithms that are very difficult to solve [14].…”

The progress of the development of digital technology today, many people communicate by sending and receiving messages. However, along with extensive technological developments, many crimes were committed. In avoiding these crimes, data security needs to be done. Form of data security in the form of cryptography and steganography. One of the cryptographic techniques is the hill cipher algorithm. Hill ciphers include classic cryptographic algorithms that are very difficult to solve. While the most popular steganography technique is Least Significant Bit (LSB). Least Significant Bit (LSB) is a spatial domain steganography technique using substitution methods. This study discusses the merging of message security with hill cipher and LSB. The message used is 24-bit color image for steganography and text with 32, 64 and 128 characters for cryptography. The measuring instruments used in this study are MSE, PSNR, Entropy and travel time (CPU time). Test results prove an increase in security without too damaging the image. This is evidenced by the results of the MSE trial which has a value far below the value 1, the PSNR is> 64 db, the entropy value ranges from 5 to 7 and the results of travel time <1 second.

“…The prime number is a positive integer a, where a ≥ 2 can only be divided by 1 and the number itself. The nature of division of integers gives birth to the concepts of prime numbers and modulo arithmetic [1,15,[17][18][19]. Most public-key algorithms use prime numbers as one of their parameter values [20,21].…”

Many public cryptography schemes rely on the use of prime numbers like for encryption and decryption. A prime number is one number that is widely used and large and consists of hundreds of digits, so it takes time to test whether the numbers are prime or not. Miller-Rabin is one algorithm that could be used to test prime number. Simulation to show how to test non-prime number elimination process can be used to determine the workings of the Miller-Rabin algorithm and also could be used as a media learning for students and lecturers to know how prime number test and generation.
