- Abstract
- Doubling of the verification equation is used to design digital signature schemes based on computational difficulty of the hidden discrete logarithm problem. This design technique allows one to use one of the signature elements as a factor in the verification equation. Due to the latter a two-dimensional cyclicity group can be used as a hidden group and general criterion of post-quantum security is satisfied. Two new digital signature algorithms are introduced as candidates for practical post-quantum cryptoschemes.
