RESUMO
In several scenarios, iti s desirable to protect not only the content of a communication, but the identities of its participants. To satisfy this property, different techniques from those used to support confidentiality and authentication are commonly required. In this work, the problem of anonymous communication on the Internet is explored through the design and implementation of specific components with this function. In particular, a name service and a routing component for anonymous environments are presented. The main contributions of this work are: (i) the study of definitions, metrics and techniques related to computational anonymity; (ii) the study of Certificateless Public Key Cryptography, a new model of public key cryptography; (iii) the design of a complete anonymization network, suitable for both generic communication and dedicated functionality; (iv) the study and design of routing schemes for anonymous communication; (v) the design of a name service to support location-hidden services in the anonymous network; (vi) the implementation of the concepts presented.
