Extension Field Cancellation: A New Central Trapdoor for Multivariate Quadratic Systems
This paper introduces a new central trapdoor for multivariate quadratic (MQ) public-key cryptosystems that allows for encryption, in contrast to time-tested MQ primitives such as U...

Post-Quantum Security Models for Authenticated Encryption
We propose a security model for evaluating the security of authenticated encryption schemes in the post-quantum setting. Our security model is based on a combination of the classic...

A note on Tensor Simple Matrix Encryption Scheme
The simple matrix encryption scheme (Tao-Diene-Tang-Ding, PQCrypto 2013) has a problem of decryption failures. Quite recently, Petzoldt-Ding-Wang (http://eprint.iacr. org/2016/010...
