Implementasi Teknik Signcryption dengan Algoritma Inam-Kanwal-Zahid-Abid dan Algoritma Schnorr pada Pesan Digital

Abstract

In exchanging information digitally, problems often occur which result in information damage. Therefore, a cryptographic method is needed in the application of signature techniques such as security for digital messages and digital signatures. Sign-then-encrypt is the method applied in this study using the Inam-Kanwal-Zahid-Abid algorithm as the message decryption encryption algorithm and the Schnorr algorithm as the digital signature algorithm. Text message security with *.docx format through a system interface designed with the C# programming language and tests were carried out on 5 text files with character lengths of 10, 100, 1000, 10000, and 100000. The results of the study concluded that the process was the same at different times on each file tested.
