Acordo de Chave Seguro contra Autoridade Mal Intencionada

Denise GoyaDionathan NakamuraRouto Terada

Certificateless key agreement protocols allow authenticated key establishment without the need of digital certificate distribution and with security level higher than the one reached by identity-based key agreement protocols. In this work, we introduce an enhanced security model that is resistant to malicious authority attacks, in which an authority is able to generate system parameters with shortcuts to session key recovery. We present a new protocol that is proved secure in this extended security model and has equivalent performance to previous ones.
