Implementación de un esquema de seguridades para servicios sobre LPV6

Abstract

Nowadays, the increase in the number of machines connected to the Internet (computers, cell phones, palms, etc.) together, with the deficient way IP addresses are allocated, have caused an early and secure shortage in the Addresses available in the lPv4 network protocol. The assignment of addresses through CIDR (Inter-Domain Routing without Classes) as well as Network Address Translation (NAT) have tried to solve this problem for lPv6 without any success, since in the first instance not all routers support CIDR and in addition There are many applications that require the use of static addresses, so NAT does not greatly help in these cases in the new generation lPv6 protocol. Taking into account another aspect and of great importance to highlight is "security", which has taken a very important role in the handling of information that is sent through electronic means. The IPv4 protocol is not very secure since it was not designed for this and many of the applications created to solve this security problem only protect the information in the highest communication layers (Application and Transport) making information vulnerable to attacks in The network layer. IPv6 on its part is presented as the most viable solution to all problems that has lPv4, since it includes among other improvements, 128-bit IP addresses, instead of 32-bit IPv4 addresses, security over The Network layer since lPv6 includes lPSec1 that allows the authentication and encryption of the base protocol itself, so that all applications can benefit
