Security in communication is very important for everyone to pay attention to. To prevent data leakage and illegal retrieval of data, cryptography and steganography can be used. In this study, GOST and XOR LSB with PRNG were used to inject text into images... see more

Mobile commerce or m-commerce is an electronic trading system (e-commerce) that uses mobile equipment such as mobile phones, smart phones, PDAs, and notebooks. With the growth of smartphone users throughout the world, many electronic commerce business own... see more

El trabajo presenta el diseño e implementación de un generador de señales moduladas en fase, el cual permite variar en un amplio rango sus parámetros de transmisión. Se buscó que el circuito final utilice una mínima cantidad de recursos de la FPGA. Esto f... see more

Securing information became essential to exchange multimedia information safely. These exchanged data need to be transformed in a well-managed, secure and reliable manner. In this paper, the focus is securing multimedia images via cryptography during tran... see more

The security of most cryptographic systems depends on key generation using a nondeterministic RNG. PRNG generates a random numbers with repeatable patterns over a period of time and can be predicted if the initial conditions and algorithms are known. TRNG... see more

We are interested in developing, using TeX/LaTeX and a pseudorandom number generator(PRNG), an automated system for student exams that would generate for each student a uniquemultiple-choice test, based on a previously constructed database of multiple-cho... see more

Gran parte de las aplicaciones electrónicas requieren de números pseudoaleatorios, en general, para mejorar su funcionamiento. Tal es el caso de los sistemas de encriptación, codificación y modulación digital. Si, además, los números pseudoaleatorios varí... see more

Penggunaan media pembelajaran di sekolah belum dimaksimalkan. Media pembelajaran belum banyak digunakan dalam proses pembelajaran di kelas ataupun pembelajaran mandiri. Penelitian ini bertujuan untuk membuat game edukasi yang valid dan praktis sebagai med... see more
