| | | | | In this article I'll cover three techniques to compute special types of polynomial products that show up in lattice cryptography and fully homomorphic encryption. Namely, the negacyclic polynomial product, which is the product of two polynomials in the quotient ring $\mathbb{Z}[x] / (x^N + 1)$. As a precursor to the negacyclic product, we'll cover the simpler cyclic product. All of the Python code written for this article is on GitHub. | |

| | | | | [AI summary] The user is interested in understanding polynomial commitments and their applications in privacy-preserving computations, particularly in blockchain. They have provided a detailed overview of FRI, Kate, and bulletproofs, along with finite field arithmetic and encoding computations into polynomial equations. The user is looking for a concise summary of the key points, further clarification on the concepts, and guidance on how to proceed with learning more about the topic. | |

| | | | | One weird hobby of mine is reasonable properties of cryptographic schemes that nobody promised they do or don't have. Whether that's invisible salamanders or binding through shared secrets, anything that isn't just boring IND-CCA2 or existential unforgeability is just delightful material to construct vulnerabilities with. Normally, with a signature scheme, you have the public key... | |
