| Abstract(in English) | The Even-Mansour cipher over bit-strings can be broken using quantum computers as shown by Kuwakado and Morii, but Alagic and Russell have given evidence that it may still be secure over certain other groups. At the same time, isogeny-based elliptic curve cryptography is a candidate for post-quantum cryptography, CSIDH key-exchange being one of the constructions. We prove pseudorandomness of a generalized Even-Mansour construction using free and transitive group actions, in a certain security model. The Hard Homogeneous Spaces inspired CSIDH uses a group action in its construction and due to its applicability and form, we define a CSIDH based instantiation. |
