Abstrak: Seiring dcngan meningkatnya penggunaan internet sebagai media pertukaran pcsan. metodc pcngamanan pcsan menjadi sangat penting. Nilai suatu pesan yang ingin dijaga keutuhan atnu intcgritasnya menycbabkan pesan tcrscbut hanya baleh dimodifikasi olch pihak yang bcrhak. Namun pada rcalitanya, pesan tersebut akan mendapat ancaman dari scorang penyusup. Bentuk ancaman terjadi apabiJa pcnyusup dcngan suatu cara. dapat mengubah isi pesan terscbut untuk bcrbagai kepcntingan. Apabila isi pesan telah bcrubah dad bentuk aslinya, maka pesan terscbut dikatakan sudah tidak aulcnlik (asli) Iagi. Snatn metodc yang efektif untuk mcnguji kcautentikan suatll pesan digllnakan tcknik kriptografi. Pada kal)'a ilmiah ini akan dibahas algoritma Message Digest 5 (MDS) dan Secure !-lash Algorithm (SHAI) untuk autentikasi pesan.
