RESUMO

The Internet grew up within the academic community in such a manner that security mechanisms were neither required nor incorporated into the original IP protocol. During the discussions to redefine and improve the actual internet protocol (IPv4), it became clear that the new project (IPv6) should incorporate some basic security characteristics. The intention was that these characteristics would provide authentication, privacy and a minimum level of security against attacks based on the protocol IP. Providing security characteristics in IPv6 (IPSec) is an important step in the direction of providing native security on the Internet. However, IPSec, does not provide a solution for all security problems that might happen when accessing the Internet. The aim of this work is to analyze the implications of the adoption of IPv6 in Secure Cooperative Environments, in particular IPSec, which provides the native security framework in the network layer, as well as the layers above it. It will be seen that the adoption of IPSec and its characteristic of end-to-end encryption, does have drawbacks since it is incompatible with the consolidated security mechanisms used currently in Secure Cooperative Environrnents (IPv4). Considering that IPv6 networks must be compatible with the existing IPv4 networks used in the Internet in order to have a gradual transition between both protocols, this work also discusses the scenarios involved when integrating the two protocols and the transition mechanisms that are relevant to each scenario
