    • ADSL: The Best Choice for Fast Internet Access 

      Rodríguez, Raquelimar; González, Rita; López, Wilfredo; González, Félix; Cruz, Alfredo (Polytechnic University of Puerto Rico, 2000-12)
      There is a real need for the increased bandwidth at a tower cost provided by ADSL (Asymmetric Digital Subscriber Line). The time is ripe for deployment due to the current competitive environment, and both A DSL transport ...

    • Cryptography and Steganography: Security in Electronic Transactions 

      Barbosa, Angel O.; Acevedo, Idelfonso; Rodríguez, Janneth; Shehadeh, Abed; Cruz, Alfredo (Polytechnic University of Puerto Rico, 2000-12)
      A new use for two ancient arts and sciences; Cryptography and Steganography are now as useful as they were thousands of years ago. The digital communication security rests mainly on the developments of these two methodologies ...

    • Cryptography: Algorithms and Security Applications 

      Cruz, Alfredo; Fernández, Maxime; Díaz, Gloria; Cosme, Alberto; Negrón, Irtalis; Negrón, Priscilla (Polytechnic University of Puerto Rico, 2000-06)
      Cryptography in Computer Science and Information Systems are broad. It is based in a sequence of steps, and its premise is only one: security. One of the latest developments in cryptography is Steganography, which is the ...

    • A Hybrid Deterministic/Genetic Test Generator to Improve Fault Effectiveness and Reduce CPU Time Run 

      Cruz, Alfredo (Polytechnic University of Puerto Rico, 2004)
