Dusan Klinec	5e6582a3fe	feat(xmr): add support for HF15, BP+	2 years ago
Dusan Klinec	25d32a8144	feat(xmr): implement bp+, refactor, code cleanup ... - implement BulletProof plus verifier and prover - use bulletproof exception to signalize proof generation failed and should be tried again. More robust, fixes bug that was not triggered yet (return tuple did not work properly in all situations) - precomputed 2**i vector is removed as it can be easily computed - BP code cleanup, minor optimizations, comments	2 years ago
Dusan Klinec	33c174491f	refactor(core/monero): Monero code cleanup ... * remove support for HF12 and below * remove MLSAG support * clean up monero cryptography naming * get rid of "optional first argument" pattern, in favor of mandatory argument that is allowed to be None (and fix several bugs related to this feature) Co-authored-by: grdddj <jiri.musil06@seznam.cz> Co-authored-by: Martin Milata <martin@martinmilata.cz> Co-authored-by: matejcik <ja@matejcik.cz>	2 years ago

Dusan Klinec	6b8fc9c894	xmr: major protocol upgrade, CLSAG support added ... - CLSAG signature scheme added - type hints added xmr: optimize protocol, send only required data - real_out_additional_tx_keys contains only one element as nothing more is needed during signature - only src_entr.outputs[index] is HMACed and always present. Other outputs are present only if needed which reduces comm and CPU overhead. - getting rid of subaddresses dictionary (memory requirements), now subaddr indices are present per source entry so keys are computed when needed xmr: prepare for permutation sending removal, specify index - specify source entry ordering index prior sorting by key images as original HMAC keys are generated based on these. - permutation checked just by valid HMACs, size of the set, key image sort order - sending permutation is now deprecated, will be removed in the following protocol versions - more strict state transition checks, guard strict check with respect to steps ordering	4 years ago
Dusan Klinec	2658e253fa	xmr/bp: memory optimizations and improvements ... - different approach to vector manipulation - more on the fly operations. Prepared for fully offloaded operations, BP on Trezor with constant memory. - memory requirements reduced from (4MN + const) to (2MN + const) - more raw methods to avoid unnecessary encoding/decoding - chunking improved, chunk size set as a constant, changed from 64 to 32, missing pieces implemented to cover also BP 16 - proof_v8 support discontinued, old hardfork, not needed anymore - get_exponent register clash fixed (for large vectors) - reduced heap fragmentation by removing some temporary allocations - hashing with len and offset to reduce heap fragmentation by creating a sliced arrays - use to() wherever possible to avoid allocations and return of mutable private object - global functions start with _ prefix, reduce import footprint - use __slots__ in classes to minimize footprint	4 years ago
