Miftah Fadillah Sopian, - (2024) IMPLEMENTASI KRIPTOGRAFI SECRET SHARING SCHEME DAN STEGANOGRAFI AUDIO LEAST SIGNIFICANT BIT MENGGUNAKAN PSEUDORANDOM HITZL-ZELE. S1 thesis, Universitas Pendidikan Indonesia.
Abstract
Pertukaran informasi semakin mudah dan cepat dengan berbagai media yang berakibat pertukaran informasi sulit dikendalikan keamanannya. Dalam rangka menghindari kebocoran informasi dan ancaman keamanan informasi lainnya, dilakukan penggabungan kriptografi dan steganografi. Kriptografi secret sharing scheme (skema (t,w)) memungkinkan pemilik informasi untuk membagikan informasi rahasia menjadi beberapa bagian, disebut sebagai share yang diberikan kepada sejumlah pemegang kunci, sehingga tidak ada pemegang kunci tunggal. Steganografi audio Least Significant Bit (LSB) digunakan untuk meyembunyikan share ke dalam file audio wav berdasarkan pseudorandom Hitzl-Zele sebagai pemilihan lokasi penyematan pada data file audio. Penggabungan kriptografi secret sharing scheme dan steganografi audio LSB menggunakan pseudorandom Hitzl-Zele diimplementasikan menjadi sebuah program aplikasi yang dikonstruksi menggunakan bahasa pemrograman Python 3.12 dan diberi nama “(t,w)-Threshold Scheme and LSB Hitzl-Zele”. Program aplikasi tersebut menunjukkan performa yang lebih baik dalam menampung informasi rahasia dengan nilai PSNR diperoleh 112,43 dB. Nilai PSNR tersebut sedikit lebih tinggi dibandingkan penelitian terkait, yaitu diperoleh 109,35 dB. Perbandingan tersebut berdasarkan nilai PSNR dari persentase panjang data bit yang disematkan dan panjang data audio sebanyak 10% dan pada file audio dengan bit depth 16-bit. The exchange of information has become easier and faster with various media, resulting in the difficulty of controlling information security. To prevent information leakage and other security threats, a combination of cryptographic and steganographic methods is used. Secret sharing scheme cryptography ((t,w)-threshold scheme) allows the owner of the information to split the secret information into several parts, called shares, which are given to multiple key holders, ensuring no single key holder has the complete information. Audio steganography Least Significant Bit (LSB) technique is used to hide the shares in a wav audio file, based on the Hitzl-Zele pseudorandom algorithm for determining the embedding locations in the audio file data. The combination of the secret sharing scheme cryptography and audio steganography LSB using the Hitzl-Zele pseudorandom algorithm was implemented as an application program constructed using Python 3.12 and named “(t,w)-Threshold Scheme and LSB Hitzl-Zele.” This application program demonstrated better performance in holding secret information with a PSNR value of 112.43 dB. This PSNR value is slightly higher compared to related research, which obtained 109.35 dB. The comparison is based on the PSNR value from the percentage of the bit length of the embedded data and the length of the audio data, which is 10% in a 16-bit depth audio file.
