* crypto: kdf - add SP800-108 counter key derivation functionStephan Müller2021-11-261-0/+5
| | | | | | | | | | | | | | | | | | | | | | | SP800-108 defines three KDFs - this patch provides the counter KDF implementation. The KDF is implemented as a service function where the caller has to maintain the hash / HMAC state. Apart from this hash/HMAC state, no additional state is required to be maintained by either the caller or the KDF implementation. The key for the KDF is set with the crypto_kdf108_setkey function which is intended to be invoked before the caller requests a key derivation operation via crypto_kdf108_ctr_generate. SP800-108 allows the use of either a HMAC or a hash as crypto primitive for the KDF. When a HMAC primtive is intended to be used, crypto_kdf108_setkey must be used to set the HMAC key. Otherwise, for a hash crypto primitve crypto_kdf108_ctr_generate can be used immediately after allocating the hash handle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all "blkcipher" algorithms have been converted to "skcipher", remove the blkcipher algorithm type. The skcipher (symmetric key cipher) algorithm type was introduced a few years ago to replace both blkcipher and ablkcipher (synchronous and asynchronous block cipher). The advantages of skcipher include: - A much less confusing name, since none of these algorithm types have ever actually been for raw block ciphers, but rather for all length-preserving encryption modes including block cipher modes of operation, stream ciphers, and other length-preserving modes. - It unified blkcipher and ablkcipher into a single algorithm type which supports both synchronous and asynchronous implementations. Note, blkcipher already operated only on scatterlists, so the fact that skcipher does too isn't a regression in functionality. - Better type safety by using struct skcipher_alg, struct crypto_skcipher, etc. instead of crypto_alg, crypto_tfm, etc. - It sometimes simplifies the implementations of algorithms. Also, the blkcipher API was no longer being tested. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | crypto: arm64/aegis128 - implement plain NEON versionArd Biesheuvel2019-08-151-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a version of the core AES transform to the aegis128 SIMD code that does not rely on the special AES instructions, but uses plain NEON instructions instead. This allows the SIMD version of the aegis128 driver to be used on arm64 systems that do not implement those instructions (which are not mandatory in the architecture), such as the Raspberry Pi 3. Since GCC makes a mess of this when using the tbl/tbx intrinsics to perform the sbox substitution, preload the Sbox into v16..v31 in this case and use inline asm to emit the tbl/tbx instructions. Clang does not support this approach, nor does it require it, since it does a much better job at code generation, so there we use the intrinsics as usual.

The other variants, AEGIS128L and AEGIS256, are not likely to ever turn up in networking protocols or other places where interoperability between Linux and other systems is a concern, nor are they likely to be subjected to further cryptanalysis. However, uninformed users may think that AEGIS128L (which is faster) is equally fit for use. So let's remove them now, before anyone starts using them and we are forced to support them forever.

Adiantum was designed by Paul Crowley and is specified by our paper: Adiantum: length-preserving encryption for entry-level processors (https://eprint.iacr.org/2018/720.pdf) See our paper for full details; this patch only provides an overview. Adiantum is a tweakable, length-preserving encryption mode designed for fast and secure disk encryption, especially on CPUs without dedicated crypto instructions. Adiantum encrypts each sector using the XChaCha12 stream cipher, two passes of an ε-almost-∆-universal (εA∆U) hash function, and an invocation of the AES-256 block cipher on a single 16-byte block. On CPUs without AES instructions, Adiantum is much faster than AES-XTS; for example, on ARM Cortex-A7, on 4096-byte sectors Adiantum encryption is about 4 times faster than AES-256-XTS encryption, and decryption about 5 times faster. Adiantum is a specialization of the more general HBSH construction. Our earlier proposal, HPolyC, was also a HBSH specialization, but it used a different εA∆U hash function, one based on Poly1305 only. Adiantum's εA∆U hash function, which is based primarily on the "NH" hash function like that used in UMAC (RFC4418), is about twice as fast as HPolyC's; consequently, Adiantum is about 20% faster than HPolyC. This speed comes with no loss of security: Adiantum is provably just as secure as HPolyC, in fact slightly *more* secure. Like HPolyC, Adiantum's security is reducible to that of XChaCha12 and AES-256, subject to a security bound. XChaCha12 itself has a security reduction to ChaCha12. Therefore, one need not "trust" Adiantum; one need only trust ChaCha12 and AES-256. Note that the εA∆U hash function is only used for its proven combinatorical properties so cannot be "broken". Adiantum is also a true wide-block encryption mode, so flipping any plaintext bit in the sector scrambles the entire ciphertext, and vice versa. No other such mode is available in the kernel currently; doing the same with XTS scrambles only 16 bytes. Adiantum also supports arbitrary-length tweaks and naturally supports any length input >= 16 bytes without needing "ciphertext stealing". For the stream cipher, Adiantum uses XChaCha12 rather than XChaCha20 in order to make encryption feasible on the widest range of devices. Although the 20-round variant is quite popular, the best known attacks on ChaCha are on only 7 rounds, so ChaCha12 still has a substantial security margin; in fact, larger than AES-256's. 12-round Salsa20 is also the eSTREAM recommendation. For the block cipher, Adiantum uses AES-256, despite it having a lower security margin than XChaCha12 and needing table lookups, due to AES's extensive adoption and analysis making it the obvious first choice. Nevertheless, for flexibility this patch also permits the "adiantum" template to be instantiated with XChaCha20 and/or with an alternate block cipher. We need Adiantum support in the kernel for use in dm-crypt and fscrypt, where currently the only other suitable options are block cipher modes such as AES-XTS. A big problem with this is that many low-end mobile devices (e.g. Android Go phones sold primarily in developing countries, as well as some smartwatches) still have CPUs that lack AES instructions, e.g. ARM Cortex-A7. Sadly, AES-XTS encryption is much too slow to be viable on these devices. We did find that some "lightweight" block ciphers are fast enough, but these suffer from problems such as not having much cryptanalysis or being too controversial. The ChaCha stream cipher has excellent performance but is insecure to use directly for disk encryption, since each sector's IV is reused each time it is overwritten. Even restricting the threat model to offline attacks only isn't enough, since modern flash storage devices don't guarantee that "overwrites" are really overwrites, due to wear-leveling. Adiantum avoids this problem by constructing a "tweakable super-pseudorandom permutation"; this is the strongest possible security model for length-preserving encryption. Of course, storing random nonces along with the ciphertext would be the ideal solution. But doing that with existing hardware and filesystems runs into major practical problems; in most cases it would require data journaling (like dm-integrity) which severely degrades performance. Thus, for now length-preserving encryption is still needed.

* crypto: chacha20-generic - refactor to allow varying number of roundsEric Biggers2018-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for adding XChaCha12 support, rename/refactor chacha20-generic to support different numbers of rounds. The justification for needing XChaCha12 support is explained in more detail in the patch "crypto: chacha - add XChaCha12 support". The only difference between ChaCha{8,12,20} are the number of rounds itself; all other parts of the algorithm are the same. Therefore, remove the "20" from all definitions, structures, functions, files, etc. that will be shared by all ChaCha versions. Also make ->setkey() store the round count in the chacha_ctx (previously chacha20_ctx). The generic code then passes the round count through to chacha_block(). There will be a ->setkey() function for each explicitly allowed round count; the encrypt/decrypt functions will be the same. I decided not to do it the opposite way (same ->setkey() function for all round counts, with different encrypt/decrypt functions) because that would have required more boilerplate code in architecture-specific implementations of ChaCha and XChaCha.

* kbuild: rename *-asn1.[ch] to *.asn1.[ch]Masahiro Yamada2018-04-071-5/+5
| | | | | | | | | | | | | | | | | Our convention is to distinguish file types by suffixes with a period as a separator. *-asn1.[ch] is a different pattern from other generated sources such as *.lex.c, *.tab.[ch], *.dtb.S, etc. More confusing, files with '-asn1.[ch]' are generated files, but '_asn1.[ch]' are checked-in files: net/netfilter/nf_conntrack_h323_asn1.c include/linux/netfilter/nf_conntrack_h323_asn1.h include/linux/sunrpc/gss_asn1.h Rename generated files to *.asn1.[ch] for consistency.

* crypto: sm4 - introduce SM4 symmetric cipher algorithmGilad Ben-Yossef2018-03-161-0/+1
| | | | | | | | | | | | | | | | Introduce the SM4 cipher algorithms (OSCCA GB/T 32907-2016). SM4 (GBT.32907-2016) is a cryptographic standard issued by the Organization of State Commercial Administration of China (OSCCA) as an authorized cryptographic algorithms for the use within China. SMS4 was originally created for use in protecting wireless networks, and is mandated in the Chinese National Standard for Wireless LAN WAPI (Wired Authentication and Privacy Infrastructure) (GB.15629.11-2003).
