This research aims to propose a safe digital video data alternative employing symmetric cryptography and an encryption technique using Partition. The Hill Cipher method requires a square key matrix with an inverse modulo the unimodular matrix is one of the unique matrices with an inverse. The encryption mechanism is modulo matrix multiplication, with shift cipher encryption employed to encrypt defective partitions. The results reveal that the videos are well encrypted and difficult for third parties to read the partition encryption technology assures that the encrypted and decrypted file sizes are the same. The background of this topic is that digital data security is increasingly important due to the increasing use of digital technology. This research aims to develop a more secure and effective video encryption algorithm by combining several cryptographic methods such as Hill cipher, partition, the shift cipher, unimodular matrix, and binary file concept logistic function. The method used in this study is experimental by using the Python programming language to implement the encryption algorithm. The trials were carried out by comparing the performance of the algorithms developed using different key sizes and variations of the combination methods used. The results show that the developed algorithm can provide a high level of security in the video encryption process with good effectiveness. The use of a combination of different cryptographic methods also has a positive impact on the resulting level of security. Therefore, the developed encryption algorithm can be a good alternative for use in securing sensitive video data.

“…En este escenario, existen circunstancias que deben ser tenidas en cuenta, tales como: el incremento en el número de estudiantes ha hecho que la disponibilidad de los recursos de laboratorio haya disminuido [14]; los costos asociados al mantenimiento y actualización de laboratorios pueden ser considerables [15]; es necesario considerar a las personas con condiciones de movilidad restringida o estudiantes a distancia [16]; e incluso la ocurrencia de eventos extraordinarios que pueden generar la disrupción de los procesos educativos, como sucedió con la pandemia de COVID-19 [13].…”

This article describes an educational experience in which a hybrid laboratory consisting of two modalities, remote and hands-on laboratory, was used in a digital electronics course focused on learning a hardware description language. A case study is presented which describes the interaction of students with the hybrid laboratory over a period of 10 weeks, including the number of experiments performed, laboratory reports submitted, and days and hours of access to the remote laboratory. In addition, responses to a question asked of students at the end of the experience, in which they were asked to indicate their preferences for the characteristics of the hybrid laboratory, are analyzed. The results show that the flexibility and accessibility of the remote laboratory were positively valued. The implications of these findings for the design of hybrid laboratories and the teaching of digital electronics are discussed
