Abstract :
Ende 7 Inpres Elementary School is a school located in Ende district, East Nusa Tenggara.
In the information system that runs at SD Inpres Ende 7 still manually, the process of
providing information is only done via whatsapp or coming directly to school. Rijndael's
algorithm applies the process of substitution, permutation and various rounds imposed on
each block for encryption and decryption. For each round, Rijndael uses an alternate key.
The key for each round is known as the RoundKey. The encryption process aims to protect
the confidentiality of digital data stored on a computer system or transmitted via the internet
or other computer networks. The Inpres Ende 7 Elementary School Information System
application is a system built by the author to make it easier for users, both teachers,
administration and students, to find out information about the school. the actor system is
divided into 2, namely superuser (admin) and normal user. The application of the Rijndael
method in school applications is on the user password. the password that has been inputted
will be encrypted with the Rijndael method. The Rijndael process starts from the first stage,
namely the initial round, the second stage is 9 round, and the third stage is the final round.
