I need to encode a small message (12bytes) into less than 32 bytes (ideally) or to produce signatures with a similar size.
RSA or other integer factorization based algorithms are not good because they need big key size (at least 1024bits) for security reasons: cipher size with RSA 1024 is 128 bytes at least and same for signature. ECC based algorithms are better because a 160 bits key size is equivalent to RSA1024. For signature, I get 42 bytes. Encoding a 12 bytes message, I get 73 bytes. If I use point compression and Jeffery's trick to remove the 'TAG' in the encrypted message, I manage to get 37 bytes. Anyone has better suggestion? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the "Crypto++ Users" Google Group.
