Homomorphic, Communitive, Secret Shares, Keyless and Quantum Robust

Secret shares

ZKP

• Zero-knowledge proof (discrete logs). ZKP. Outlines zero-knowledge proof.

• Zero-knowledge proof (Feige-Fiat-Shamir). ZKP. Outlines zero-knowledge proof using the Feige-Fiat-Shamir method.

• Zero-knowledge proof (non-interactive random oracle access). ZKP. Non-interactive random oracle access for the Fiat-Shamir heuristic.

• Zero-knowledge proof (Graphs). ZKP. Outlines zero-knowledge proof using graphing methods.

• Fair coin flip. ZKP. Outlines how a fair coin flip can be created, without a trusted verifier.

• Voting with Paillier crypto system. ZKP. Outlines voting with Paillier crypto system.

• Oblivious transfer. OT. Oblivious transfer.

• Scrambled circuits. Scrambled. Scrambled circuits - SFE.

• Millionaire's Problem . Mill. Yao's Millionaire Problem.

• RAPPOR. RAPPOR. Outlines RAPPOR (Randomized Aggregatable Privacy-Preserving. Ordinal Response) which allows for privacy in gathered data.

Quantum Robust

• Lattice-based cryptography [Lattice] – This classification shows great potential and is leading to new cryptography, such as for fully homomorphic encryption [here], and code obfuscation. An example is given in the following section.

• Code-based cryptography [McEliece] – This method was created in 1978 with the McEliece cryptosystem but has barely been using in real applications. The McEliece method uses linear codes that are used in error correcting codes, and involves matrix-vector multiplication. An example of a linear code is Hamming code [here].

• Multivariate polynomial cryptography [UOV] – These focus on the difficulty of solving systems of multivariate polynomials over finite fields. Unfortunately, many of the methods that have been proposed have already been broken.

• Hash-based signatures [GMSS] – This would involve created digital signatures using hashing methods. The drawback is that a signer needs to keep a track of all of the messages that have been signed, and that there is a limit to the number of signatures that can be produced.
