Add to ORKGThe past few years have seen the rising of the quantum computers, that are a serious threat to nearly all the actual cryptographic schemes used in practice. In this thesis we propose some new constructions to prevent this obsolescence by building our schemes on the mathematical tool of lattices that is assumed post-quantum resistant. We firstly develop a group signature scheme, allowing each member composing the group to anonymously sign on the behalf of the group. We add a supplementary property, which is the froward secrecy. This property cut the time in periods, such that each secret key is updated when entering a new period. We also propose a blind signature scheme, which is an interactive protocol between an user, who wants to sign a m...
