An apparatus for encryption according to an embodiment of the present disclosure comprises a classifier configured to classify each data included in an original data set into one of encryption target data and non-encryption target data on the basis of at least one of determination on whether or not an operation to be applied to each data included in the original data set for an analysis of the original data set is a preset operation and determination on whether or not each data included in the original data set is sensitive information; and an encryptor configured to encrypt the encryption target data among the data included in the original data set using a homomorphic encryption algorithm.

Encryption apparatus and method for encrypting encryption target data in data based on homomorphic encryption algorithm

There are provided a message communication device and method. A message communication device according to an exemplary embodiment includes a header modifying unit configured to modify a message header by adding additional information used together with an identity when a public key corresponding to the identity of a recipient is generated to be the message header, and a message transmitting unit configured to transmit a message including data encrypted based on the public key and the modified message header.
