Analysis of Hidden Field Equations Cryptosystem over Odd-Characteristic Fields
N. G. Kuzmina and E. B. Makhovenko

Some results on cryptanalysis of Hidden Field Equations (HFE) cryptosystem over oddcharacteristic fields are presented. Using of odd-char HFE schemes reduces key generation, encryption and decryption time. Possible attacks are analyzed. HFE parameters, for which cryptosystem is resistant to a given set of attacks, are revealed. Recommendations for HFE parameters choice are provided.


Key words: postquantum cryptography, Hidden Field Equations, odd-characteristic fields
