# CHANGELOG
|
|
|
|
## [0.3.2] - 2025-10-27
|
|
|
|
### `poulpy-schemes`
|
|
- Added `sign` argument to GGSW-based blind rotation, which enables to choose the rotation direction of the test vector.
|
|
|
|
## [0.3.2] - 2025-10-27
|
|
|
|
### `poulpy-hal`
|
|
- Improved convolution functionality
|
|
|
|
### `poulpy-core`
|
|
- Rename `GLWEToLWESwitchingKey` to `GLWEToLWEKey`.
|
|
- Rename `LWEToGLWESwitchingKey` to `LWEToGLWEKey`.
|
|
- Add `GLWESecretTensor` which stores the flattened upper right of the tensor matrix of the pairs `sk[i] * sk[j]`.
|
|
- Add `GGLWEToGGSWKey`, `GGLWEToGGSWKeyPrepared`, `GGLWEToGGSWKeyCompressed`, which encrypts the full tensor matrix of all pairs `sk[i] * sk[j]`, with one `GGLWE` per row.
|
|
- Update `GGLWEToGGSW` API to take `GGLWEToGGSWKey` instead of the `GLWETensorKey`
|
|
- Add `GLWETensor`, the result of tensoring two `GLWE` of identical rank.
|
|
- Changed `GLWETensorKey` to be an encryption of `GLWESecretTensor` (preliminary work for `GLWEFromGLWETensor`, a.k.a relinearization).
|
|
|
|
### `poulpy-schemes`
|
|
- Add `GLWEBlindRotation`, a `GGSW`-based blind rotation that evaluates `GLWE <- GLWE * X^{((k>>bit_rsh) % 2^bit_mask) << bit_lsh}.` (`k` = `FheUintBlocksPrepared`).
|
|
- Add `GGSWBlindRotation`, a `GGSW`-based blind rotation that evaluates `GGSW <- (GGSW or ScalarZnx) * X^{((k>>bit_rsh) % 2^bit_mask) << bit_lsh}.` (`k` = `FheUintBlocksPrepared`).
|
|
|
|
## [0.3.1] - 2025-10-24
|
|
|
|
### `poulpy-hal`
|
|
- Add bivariate convolution (X, Y) / (X^{N} + 1) with Y = 2^-K
|
|
|
|
### `poulpy-core`
|
|
- Fix typo in impl of GGLWEToRef for GLWEAutomorphismKey that required the data to be mutable.
|
|
|
|
## [0.3.0] - 2025-10-23
|
|
|
|
- Fixed builds on MACOS
|
|
|
|
### Breaking changes
|
|
- The changes to `poulpy-core` required to break some of the existing API. For example the API `prepare_alloc` has been removed and the trait `Prepare<...>` has been broken down for each different ciphertext type (e.g. GLWEPrepare). To achieve the same functionality, the user must allocated the prepared ciphertext, and then call prepare on it.
|
|
|
|
### `poulpy-hal`
|
|
- Added cross-base2k normalization
|
|
|
|
### `poulpy-core`
|
|
- Added functionality-based traits, which removes the need to import the low-levels traits of `poulpy-hal` and makes backend agnostic code much cleaner. For example instead of having to import each individual traits required for the encryption of a GLWE, only the trait `GLWEEncryptSk` is needed.
|
|
|
|
### `poulpy-schemes`
|
|
- Added basic framework for binary decicion circuit (BDD) arithmetic along with some operations.
|
|
|
|
## [0.2.0] - 2025-09-15
|
|
|
|
### Breaking changes
|
|
- Updated the trait `FillUniform` to take `log_bound`.
|
|
|
|
### `poulpy-hal`
|
|
- Added pure Rust reference code for `vec_znx` and `fft64` backend.
|
|
- Added cross-backend generic test suite along with macros.
|
|
- Added benchmark generic test suite.
|
|
|
|
### `poulpy-backend`
|
|
- Added `FFTRef` backend, which provides an implementation relying on the reference code of `poulpy-hal`.
|
|
- Added `FFTAvx` backend, which provides a pure Rust AVX/FMA accelerated implementation of `FFTRef` backend.
|
|
- Added cross-backend tests between `FFTRef` and `FFTAvx`.
|
|
- Added cross-backend tests between `FFTRef` and `FFT64Spqlios`.
|
|
|
|
### `poulpy-core`
|
|
- Removed unsafe blocks.
|
|
- Added tests suite for `FFTRef` and `FFTAvx` backends.
|
|
|
|
### Other
|
|
- Fixed a few minor bugs.
|
|
|
|
## [0.1.0] - 2025-08-25
|
|
- Initial release. |
