Detailed Description
struct ECIES< EC, HASH, COFACTOR_OPTION, DHAES_MODE, LABEL_OCTETS >
Elliptic Curve Integrated Encryption Scheme.
- Template Parameters
-
COFACTOR_OPTION cofactor multiplication option HASH HashTransformation derived class used for key derivation and MAC computation DHAES_MODE flag indicating if the MAC includes additional context parameters such as u·V, v·U and label LABEL_OCTETS flag indicating if the label size is specified in octets or bits
ECIES is an Elliptic Curve based Integrated Encryption Scheme (IES). The scheme combines a Key Encapsulation Method (KEM) with a Data Encapsulation Method (DEM) and a MAC tag. The scheme is IND-CCA2, which is a strong notion of security. You should prefer an Integrated Encryption Scheme over homegrown schemes.
If you desire an Integrated Encryption Scheme with Crypto++ 4.2 compatibility, then use the ECIES_P1363. If you desire an Integrated Encryption Scheme compatible with Bouncy Castle 1.54 and Botan 1.11 compatibility, then use the ECIES template class with NoCofactorMultiplication, DHAES_MODE=true and LABEL_OCTETS=false.
The default template parameters ensure compatibility with Bouncy Castle 1.54 and Botan 1.11. The combination of IncompatibleCofactorMultiplication and DHAES_MODE=true is recommended for best efficiency and security. SHA1 is used for compatibility reasons, but it can be changed if desired.
