- Efecto de la expansión del espacio de mensajes sobre la longitud de la información y los tiempos de cifrado y descifrado del protocolo basado en el esquema criptográfico con curvas elípticas (eces) Jorge Sega Ingeniería The protocol of encoding ECES is catalogued within the Elliptic Curve Cryptosystems, having a high computational complexity, and therefore, a great security, greater than cryptosystems based on the discreet logarithm or factorization. However, this protocol presents a problem of slowness for the transmission of the information, associated to its length, and to the times it takes for the coding and decoding of the messages. This investigation was based on modifying the ECES protocol, so that its space of messages expanded. The investigation type is exploratory and explicative; its design is experimental. The method applied to expand this space was to apply the isomorphism that is present in certain families of elliptical curves, to the protocol. Then, the efficiency of both ECES protocols (the original one as well as the modified one) is compared, based on the length of the information, and the times of coding and decoding. The results obtained in this investigation reflect that the disadvantages alluded previously, have been alleviated, increasing the speed of the communications encrypted with elliptical curves. The length of the message has been managed to reduce in 11%. The times of the coding and decoding, per block and per bit, have been reduced, too. Then, one concludes these improvements are given as a result of the expansion of the space of messages 2005 artículo científico 1856-4194 https://www.redalyc.org/articulo.oa?id=78440205 en http://www.redalyc.org/revista.oa?id=784 Télématique application/pdf Universidad Privada Dr. Rafael Belloso Chacín Télématique (República Bolivariana de Venezuela) Num.2 Vol.4
