268a039 Optimized keccak implementation (SChernykh)
2022-04-18Optimized keccak implementationSChernykh1-33/+62
All tests were conducted on the same PC (Ryzen 5 5600X running at fixed 4.65 GHz). Before: test_cn_fast_hash<32> (100000 calls) - OK: 1 us/call test_cn_fast_hash<16384> (1000 calls) - OK: 164 us/call After: test_cn_fast_hash<32> (100000 calls) - OK: 0 us/call test_cn_fast_hash<16384> (1000 calls) - OK: 31 us/call More than 5 times speedup for cn_fast_hash. Also noticed consistent 1-2% improvement in test_construct_tx results.
2022-04-18Add view tags to outputs to reduce wallet scanning timej-berman2-1/+43
Implements view tags as proposed by @UkoeHB in MRL issue https://github.com/monero-project/research-lab/issues/73 At tx construction, the sender adds a 1-byte view tag to each output. The view tag is derived from the sender-receiver shared secret. When scanning for outputs, the receiver can check the view tag for a match, in order to reduce scanning time. When the view tag does not match, the wallet avoids the more expensive EC operations when deriving the output public key using the shared secret.

2019-02-25discontinue use of allocamoneromooo-monero1-12/+2
NetBSD emits: warning: Warning: reference to the libc supplied alloca(3); this most likely will not work. Please use the compiler provided version of alloca(3), by supplying the appropriate compiler flags (e.g. not -std=c89). and man 3 alloca says: Normally, gcc(1) translates calls to alloca() with inlined code. This is not done when either the -ansi, -std=c89, -std=c99, or the -std=c11 option is given and the header <alloca.h> is not included. Otherwise, (without an -ansi or -std=c* option) the glibc version of <stdlib.h> includes <alloca.h> and that contains the lines: #ifdef __GNUC__ #define alloca(size) __builtin_alloca (size) #endif It looks like alloca is a bad idea in modern C/C++, so we use VLAs for C and std::vector for C++.

5fd83c13 Cryptonight variant 2 (SChernykh)
2018-09-09Cryptonight variant 2SChernykh2-54/+361
Contains two modifications to improve ASIC resistance: shuffle and integer math. Shuffle makes use of the whole 64-byte cache line instead of 16 bytes only, making Cryptonight 4 times more demanding for memory bandwidth. Integer math adds 64:32 bit integer division followed by 64 bit integer square root, adding large and unavoidable computational latency to the main loop. More details and performance numbers: https://github.com/SChernykh/xmr-stak-cpu/blob/master/README.md

2018-03-14crypto: revert odd namespace changes made in #3303stoffu2-10/+1
2018-03-14device: untangle cyclic depenencystoffu3-89/+0
When #3303 was merged, a cyclic dependency chain was generated: libdevice <- libcncrypto <- libringct <- libdevice This was because libdevice needs access to a set of basic crypto operations implemented in libringct such as scalarmultBase(), while libringct also needs access to abstracted crypto operations implemented in libdevice such as ecdhEncode(). To untangle this cyclic dependency chain, this patch splits libringct into libringct_basic and libringct, where the basic crypto ops previously in libringct are moved into libringct_basic. The cyclic dependency is now resolved thanks to this separation: libcncrypto <- libringct_basic <- libdevice <- libcryptonote_basic <- libringct This eliminates the need for crypto_device.cpp and rctOps_device.cpp. Also, many abstracted interfaces of hw::device such as encrypt_payment_id() and get_subaddress_secret_key() were previously implemented in libcryptonote_basic (cryptonote_format_utils.cpp) and were then called from hw::core::device_default, which is odd because libdevice is supposed to be independent of libcryptonote_basic. Therefore, those functions were moved to device_default.cpp.

2018-03-04Code modifications to integrate Ledger HW device into monero-wallet-cli.cslashm7-6/+115
The basic approach it to delegate all sensitive data (master key, secret ephemeral key, key derivation, ....) and related operations to the device. As device has low memory, it does not keep itself the values (except for view/spend keys) but once computed there are encrypted (with AES are equivalent) and return back to monero-wallet-cli. When they need to be manipulated by the device, they are decrypted on receive. Moreover, using the client for storing the value in encrypted form limits the modification in the client code. Those values are transfered from one C-structure to another one as previously. The code modification has been done with the wishes to be open to any other hardware wallet. To achieve that a C++ class hw::Device has been introduced. Two initial implementations are provided: the "default", which remaps all calls to initial Monero code, and the "Ledger", which delegates all calls to Ledger device.

2017-12-16Scrub keys from memory just before scope end.moneromooo-monero2-17/+10
Partially implements #74. Securely erases keys from memory after they are no longer needed. Might have a performance impact, which I haven't measured (perf measurements aren't generally reliable on laptops). Thanks to @stoffu for the suggestion to specialize the pod_to_hex/hex_to_pod functions. Using overloads + SFINAE instead generalizes it so other types can be marked as scrubbed without adding more boilerplate.

2016-11-07wallet: fix output collision detection for view walletsmoneromooo-monero1-1/+1
View wallets do not have the spend secret key, and are thus unable to derive key images for incoming outputs. Moreover, a previous patch set key images to zero as a means to mark an output as having an unknown key image, so they could be filled in when importing key images at a later time. That later patch caused spurious collisions. We now use public keys to detect duplicate outputs. Public keys obtained from the blockchain are checked to be identical to the ones derived locally, so can't be spoofed.

Keep the immediate direct deps at the library that depends on them, declare deps as PUBLIC so that targets that link against that library get the library's deps as transitive deps. Break dep cycle between blockchain_db <-> crytonote_core. No code refactoring, just hide cycle from cmake so that it doesn't complain (cycles are allowed only between static libs, not shared libs). This is in preparation for supproting BUILD_SHARED_LIBS cmake built-in option for building internal libs as shared.

This allows the key to be not the same for two outputs sent to the same address (eg, if you pay yourself, and also get change back). Also remove the key amounts lists and return parameters since we don't actually generate random ones, so we don't need to save them as we can recalculate them when needed if we have the correct keys.
