Public key cryptography relies on using mathematical functions that are easy to compute but hard to invert. A recent work by D'Alconzo, Flamini, and Gangemi attempted to build such a function from tensors and use it to create a commitment scheme. In this talk, we will review their construction and present an attack on it, rendering it completely insecure. We will also offer an approach to repairing it.

The talk is based on the work from https://eprint.iacr.org/2024/337, but no prior knowledge is necessary.
