Uma função MAC baseada em função de compressão chamada FMAC foi apresentada, bem como um PRF de entrada vetorial chamado vFMAC em 2016. Eles foram comprovados como PRFs seguros na suposição de que sua função de compressão é um PRF seguro contra ataques de chave relacionada com respeito às suas permutações não criptográficas na configuração de usuário único. Neste artigo, é mostrado que FMAC e vFMAC também são PRFs seguros na configuração multiusuário, na mesma suposição que na configuração de usuário único. Esses resultados implicam que sua segurança na configuração multiusuário não se degrada com o número de usuários e é tão boa quanto na configuração de usuário único.

Abstract: A compression-function-based MAC function called FMAC was presented as well as a vector-input PRF called vFMAC in 2016. They were proven to be secure PRFs on the assumption that their compression function is a secure PRF against related-key attacks with respect to their non-cryptographic permutations in the single user setting. In this paper, it is shown that both FMAC and vFMAC are also secure PRFs in the multi-user setting on the same assumption as in the single user setting. These results imply that their security in the multi-user setting does not degrade with the number of the users and is as good as in the single user setting.
