• New fft backend primitives
• Parallel generation of CBS PFPKSK
• Removed fftw backend
• Fix backwards as torus for fft backend
• Fix bad size check in wop PBS public API

Summary

Concrete-core V1.0.0 has been designed to be an integration platform for hardware acceleration of FHE. It comes with a CPU implementation of the low level primitives of TFHE, and a GPU implementation of some of them. Compared to the V0.1.10 release, the main new changes are:

• The transformation of Concrete-core into a platform for hardware integration, with a plugin system for hardware contributions, and a test & benchmark harness
• Support for serialization
• Enhanced error management
• The introduction of public key cryptography for the LWE scheme
• The introduction of seeded ciphertexts & keys to reduce memory footprint
• Parallel bootstrap key generation
• The addition of primitives to perform a large precision bootstrap (up to 16 bits of message precision) without having to rely on an increase of the polynomial size, which is not performant. This bootstrap is often referred to as a "without padding bit bootstrap", abbreviated as wop PBS.
• The replacement of FFTW with a Rust FFT implementation
• Support for Apple Silicon chips besides x86_64 platforms
• Experimental support for Windows
• Cuda acceleration for the keyswitch, bootstrap and sub-components of the large precision bootstrap
• The introduction of C and WASM APIs to use Concrete-core via other languages than Rust
