Method Details

generatePartialPublicKey

public PublicKey generatePartialPublicKey()

generates a partial public key stores a partial private key corresponding to the partial public key in ctx

Returns:

the partial public key

setPublicKey

public void setPublicKey(PublicKey public_key)

sets the public key and stores it in ctx

Parameters:

public_key - the public key to set

encrypt

public CiphertextMatrix encrypt(MatrixObject plaintext)

encrypts one block of data with public key stored statically and returns it setPublicKey() must have been called before calling this

Parameters:

plaintext - the MatrixObject to encrypt

Returns:

the encrypted matrix

partiallyDecrypt

public PlaintextMatrix partiallyDecrypt(CiphertextMatrix ciphertext)

partially decrypts ciphertext with the partial private key. generatePartialPublicKey() must have been called before calling this function

Parameters:

ciphertext - the ciphertext to partially decrypt

Returns:

the partial decryption of ciphertext
