This submission contains a generic C implementation of the LEA cipher algorithm and test vectors for it. It also includes modifications to use the LEA in fscrypt.
The LEA algorithm is a lightweight block cipher that processes data blocks of 128-bits and has three different key lengths, each with a different number of rounds:
- LEA-128: 128-bit key, 24 rounds,
- LEA-192: 192-bit key, 28 rounds, and
- LEA-256: 256-bit key, 32 rounds.
The round function of LEA consists of 32-bit ARX(modular Addition, bitwise Rotation, and bitwise XOR) operations. See [2, 5, 7] for details.
LEA is a Korean national standard block cipher, described in "KS X 3246"[1] and is also included in the international standard, "ISO/IEC 29192-2:2019 standard"[2].
It is one of the approved block ciphers for the current Korean Cryptographic Module Validation Program (KCMVP).
We expect that the first application of the patch would be disk encryption on the Gooroom platform ('Gooroom' is a Korean word, meaning 'cloud') [3]. Currently, the Gooroom platform uses AES-XTS for disk encryption. The main reason for submitting this patch is to make disk encryption with LEA (e.g. LEA-XTS) available on there. It is possible to use LEA without any additional modifications in dm-crypt, a module that provides disk encryption functionality within the kernel.
This patch also includes a modification to enable LEA for use in fscrypt, another data-at-rest method available within the kernel, and a modification to blk-crypto-fallback to enable the "inlinecrypt" mount option in fscrypt.
The Gooroom platform is a government-driven Debian-based Linux distribution in South Korea. In Korea, there are many crypto companies that want to bundle Linux into their products and sell them. They create their own Gooroom platforms by modifying the original Gooroom platform for their services. (Of course, the Gooroom platform is not mandatory, and companies wishing to use Linux are free to choose an appropriate distribution.) BTW, in Korea, many crypto companies want to use LEA, because LEA is one of the block ciphers of the KCMVP, a validation program for commercial crypto S/W to be delivered to the Korean government.
The Linux Crypto API already has another Korean block cipher, ARIA, also one of the block ciphers of the KCVMP. However, LEA is more widely used than ARIA in industry nowadays, because LEA is one of the lightweight cryptography standard of ISO/IEC [2] and performs well on low-end devices that support 32-bit operations. So we think they are complementary to each other.
In general, it's obvious that the hardware-accelerated AES is the best performer. However, there exist not only environments where the hardware-accelerated AES is not supported, but also situations where AES is not preferred for various reasons. In these cases, if someone wants to encrypt using a block cipher, LEA could be an alternative.
There are also SIMD implementations for efficiently using LEA, which is not included in this patch. We have SSE2 and AVX2 assembly implementations, some of which were included in the previous version of the patch. The SIMD implementations are being re-implemented to support a wider range of environments.
Apart from this, we also have implemented LEA in lightweight environments such as 8-bit AVR, 16-bit MSP and 32-bit ARM [4]. If LEA were to be included in the Linux kernel, it would be possible to modify and supplement the submission with lightweight implementations to provide efficient encryption on embedded linux devices.
Although the designers of LEA did not provide test vectors in their paper [5], the ISO/IEC standard [2] and the KS standard [1] do. Furthermore, the Block Cipher LEA Specification("블록암호 LEA 규격서", written in Korean) document on the LEA introduction page [6] and the Wikipedia article on LEA [7] show the same test vectors as in the standards.
The test vectors for ECB, CBC, CTR, and GCM modes included in the testmgr module are taken from the KCMVP Cryptographic Algorithm Verification Criteria V3.0("KCMVP 검증대상 암호알고리즘 검증기준 V3.0", written in Korean) [8]. Test vectors for the XTS mode were generated by ourselves, and we crosschecked them using Crypto++ [9] and testmgr on Linux.
The implementation has been tested with kernel module tcrypt.ko and has passed the selftest using above-mentioned test vectors. It also has been tested with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS. The fscrypt patch was tested using a modified tool by forking https://github.com/google/fscrypt.

Add LEA-256-XTS, LEA-256-CTS fscrypt support.
LEA is a South Korean 128-bit block cipher (with 128/192/256-bit keys)
included in the ISO/IEC 29192-2:2019 standard (Information security -
Lightweight cryptography - Part 2: Block ciphers). It shows fast
performance and, when SIMD instructions are available, it performs even
faster. Particularly, it outperforms AES when the dedicated crypto
instructions for AES are unavailable, regardless of the presence of SIMD
instructions. However, it is not recommended to use LEA unless there is
a clear reason (such as the absence of dedicated crypto instructions for
AES or a mandatory requirement) to do so. Also, to enable LEA support,
it needs to be enabled in the kernel crypto API.

The single block test vectors are taken from the standard documentation.
The test vectors for ECB, CBC, CTR, and GCM are taken from the KCMVP
Cryptographic Algorithm Verification Criteria V3.0.
Test vectors for the XTS mode were generated by ourselves,
and we crosschecked them using Crypto++ and testmgr on Linux.

LEA is a 128-bit block cipher developed by South Korea.
LEA is a Korean national standard (KS X 3246) and included in the
ISO/IEC 29192-2:2019 standard (Information security - Lightweight
cryptography - Part 2: Block ciphers).
The LEA algorithm is a symmetric key cipher that processes data blocks
of 128-bits and has three different key lengths, each with a different
number of rounds:
- LEA-128: 128-bit key, 24 rounds,
- LEA-192: 192-bit key, 28 rounds, and
- LEA-256: 256-bit key, 32 rounds.
The round function of LEA consists of 32-bit ARX(modular Addition,
bitwise Rotation, and bitwise XOR) operations.

This will only be true once there is actually an applicable implementation of
LEA-XTS and LEA-CTS using SIMD instructions included in the kernel.
Perhaps it is your plan to go through and accelerate LEA-XTS and LEA-CTS for the
common CPU architectures. However, it is not included in this patchset yet, so
it should not be claimed in the documentation yet.

I think I'd prefer that you omit the mention of the "absence of dedicated crypto
instructions" use case for now. fscrypt already supports another algorithm that
fulfills exactly that use case (Adiantum), and that algorithm already has
optimized implementations for arm32, arm64, and x86_64. LEA does not have that
yet. So it does not really bring anything new to the table. I'm also unsure it
would be appropriate to recommend a "lightweight" cipher at this point...
That would leave "mandatory requirement" as the rationale, at least for now,
similar to SM4.

As you might expect, we are working on a SIMD implementation of LEA in a
general-purpose CPU environment. However, since no such implementation has
been submitted yet, we agree that it's right to leave it out for now.
In the next version, we would like to change the description to the
following:
LEA is a South Korean 128-bit block cipher (with 128/192/256-bit keys)
included in the ISO/IEC 29192-2:2019 standard (Information security -
Lightweight cryptography - Part 2: Block ciphers). If dedicated cipher
instructions are available, or other options with performance benefits
are available, using LEA is likely not a suitable choice. Therefore,
it is not recommended to use LEA-256-XTS unless there is a clear reason
to do so, such as if there is a mandate. Also, to enable LEA support,
it needs to be enabled in the kernel crypto API.

Thanks for the feedback.
We'll remove the documentation and submit the next version.

I've sent out
https://lore.kernel.org/linux-fscrypt/[email protected]/T/#u.
One of the things it does is add a nice list for the "national pride ciphers".
So we can just add ciphers like SM4 and LEA, and any that people might insist on
adding in the future like Camellia, Kuznyechik, SEED, ARIA, etc., to that list,
and not have to waste time with each one individually...

That seems reasonable enough to us.
Thank you for your consideration.
