1. Identity-based cryptography environment. / Um ambiente criptográfico baseado na identidade.
The accelerated growth of Internet-based business increase significantly the need for mechanisms that can guarantee the data confidentiality, providing tools for authenticity and non-repudiation users in any medium of communication, even with computer resources becoming increasingly scarce, eg into a cell phone. This paper describes an encryption scheme that

2. Análise de segurança de esquemas de privacidade de dados
This dissertation walks through the Advantage Function Model, from Goldwasser and Bellare, explaining its complex concepts and exemplifying its application in the analysis of encryption security schemes currently used in practice. It is also shown ways to put this model into practice. The safety of the schemes used in the IEEE 802.11 Standard are explained a

4. AnÃlise e resultados experimentais de sistemas de distribuiÃÃo quÃntica de chaves usando fÃtons isolados e estados coerentes mesoscÃpicos. / Theorical analysis and experimental results of quantum key distribution systems using single-photons and mesoscopic coherent states
In this dissertation it is realized a study about quantum key distribution (QKD) in optical networks. Initially, a review of the theory of quantum key distribution and some of its implementations with strongly attenuated coherent states, as well a review of an optical system for physical encryptation using mesoscopic coherent states are realized. Following,

5. "Proposal for encryption and signature schemes under certificateless public key cryptography model" / "Proposta de esquemas de criptografia e de assinatura sob modelo de criptografia de chave pública sem certificado"
Under the model of Identity Based Cryptography (ID-PKC), the public key can be the user s identity, therefore it does not require a Public Key Infrastructure (PKI) with its complex management of Digital Certificates. On the other hand, this system requires a Private Key Generator (PKG), a trusted authority who is in possession of a master key and can generat
