Puskesmas is a place to provide health and medical services for the community. Every patient who seeks treatment at a doctor at the health center always gets a message containing a prescription for the drug. The problem that often occurs is the large number of drug prescribing processes that occur without being based on a system, can cause errors in drug prescribing and can be fatal for patients. The purpose of this research is to make an electronic encrypted prescription application using the Vigener Cipher method. The implementation of this system uses the Vigener Cipher Algorithm in securing prescription drug data. The Vigener Cipher algorithm can perform encryption and decryption processes. System Design with Context Diagram. The result of this study is that the application of drug prescribing data using the Vigener Cipher Algorithm has been able to secure drug prescribing properly. In the PARASETAMOL Drug Data Test, key: CXWDFHHJYVW, result: RXNDXLAJKJH. Functional Testing Results obtained results that are accepted in all test scenarios and Validity Test Results obtained 100% valid results.

“…Cryptography is a branch of science that studies how to secure and protect the information (data) that is sent. The two main concepts of cryptography are encryption and decryption (Hasan et al, 2020). The aim is to maintain the confidentiality of messages sent so that they are not known by unauthorized and irresponsible people.…”

“…The Hill Cipher method is one of several methods in cryptography. This matrix is an (Hasan et al, 2020). Hill Cipher does not replace each of the same letters in the plaintext with other letters that are the same in the ciphertext because it uses matrix multiplication as a basis for encryption and decryption (Endaryono et al, 2021) (Permata Dewi et al, 2022.…”

The security of the data (message) sent is very important in maintaining the confidentiality of the message. Many algorithms can be used to secure messages. Among them is the Hill Cipher algorithm. The Hill Cipher algorithm is a classic cryptographic algorithm. This algorithm uses a square matrix key. In connection with the Hill Cipher algorithm key, this literature aims to examine the matrix that can be used as a key in the encryption and decryption process in the Hill Cipher algorithm. In this literature, we take a square matrix of order 3x3 and use 36 characters (A-Z, 0-9). To produce cipher text, the method used is to carry out an encryption process based on the Hill Cipher algorithm. The encryption process is carried out by multiplying the key matrix by the plaintext. The decryption process to get the plain text back is done by multiplying the ciphertext by the inverse modulo matrix of the key matrix. The encryption process can always be carried out, but not all decryption processes can be carried out. Because not all matrices can be used as key matrices. The results of this literature show that the key matrix must be a matrix of order mxm. A matrix with determinant value = 0 cannot be used as a key. Likewise, a matrix whose determinant value is not relatively prime with the number of characters to be encrypted or decrypted cannot be used as a key matrix

“…Furthermore, a study [12] examines using Hill Cipher for the encryption and decryption process using rectangular matrix keys. The research [13] discusses text data security by applying Hill Cipher to Telephone Codes and the Five Modulus Method. The topic of Hill Cipher algorithm hybrid cryptography as the development of symmetric key cryptography [14] discusses how to secure student academic grades using the Hill Cipher hybrid algorithm.…”

In the process of exchanging data and information, the most important task is to maintain data and information security and reach out to interested parties. One way this can be achieved is through encryption, a process better known as cryptography. Cryptography can scramble messages so that, even if intercepted, the message cannot be immediately read. One example of an encryption algorithm is the Hill Cipher. The Hill Cipher uses an m-by-m-sized matrix as the key for the encryption and decryption process, making it a challenging algorithm to crack. The key provided for the Hill Cipher encryption and decryption process cannot be arbitrary. The keys with mismatched determinants cannot be used, as they can prevent the encrypted message from being restored to its original form. Optimization can be carried out to overcome these obstacles using a genetic algorithm. Genetic algorithms can determine the keys to encrypt and decrypt the Hill Cipher. A key with the appropriate composition for the Hill Cipher will be obtained through the genetic algorithm's evaluation function. This research aims to enhance message security by using the correct composition to generate Hill Cipher encryption and decryption keys. The research results indicate that out of 10 tests conducted with different lengths of original text, eight succeeded, while two failed to complete the encryption and decryption process.
