Contains the underlying primitives that are used in both pke and binfhe.

Lattice

• Contains files that support lattice/polynomial-layer operations in OpenFHE. This layer is used to represent polynomial rings and support operations over those rings.

• As can be seen above, this is the "middle" layer between higher-level lattice cryptography elements, and the lower level math operations.

Math

Contains various files describing the mathematical functionality supported in OpenFHE. For example:

• modular arithmeric
• sampling functions

In addition, the hardware abstraction layer (HAL) is defined here.

Utils

Contains various utilities:

• debugging utilities
• memory management utilities
• parallel operations
• serialization
