This is a GnuPG-like unix program for encryption and signing that uses
|
||
|
|
only quantum-computer-resistant algorithms:
|
||
|
|
|
||
|
|
+ McEliece cryptosystem (compact QC-MDPC variant) for encryption
|
||
|
|
+ Hash-based Merkle tree algorithm (FMTSeq variant) for digital
|
||
|
|
signatures
|
||
|
|
|
||
|
|
Stream ciphers used: ChaCha20, XSynd stream cipher, RC4 (for initial
|
||
|
|
simplicity of implementation)
|
||
|
|
|
||
|
|
CRHFs used:
|
||
|
|
+ Cubehash variants were selected for implementation ease, really
|
||
|
|
clean design, quite good speed and flexibility of parameter choices.
|
||
|
|
KeyID's are CUBE256 hashes of serialized public key.
|
||
|
|
+ ripemd128 for small hashes
|
||
|
|
+ tiger192 is used as an alternative for Cubehash for 192bit hashes
|
||
|
|
+ There's always a variant with SHA-256, SHA-384 or SHA-512.
|
||
|
|
|
||
|
|
Signature algorithms:
|
||
|
|
+ FMTSeq with many possibilities and combinations of aforementioned CRHFs
|
||
|
|
|
||
|
|
Encryption:
|
||
|
|
MDPC McEliece on quasi-cyclic matrices - decoding is (slightly)
|
||
|
|
vulnerable to timing attacks.
