enc: Encrypt a message

In iamtrask/R-Homomorphic-Encryption-Package: Fully Homomorphic Encryption

Description

This encrypts an integer message under one of the homomorphic encryption schemes supported by this package.

Usage

enc(pk, m)

Arguments

pk	a public key for any scheme as generated by the keygen. function.
m	an integer to be encrypted. Note that the permissable range of values for m is dependent on the scheme and the parameters of the scheme. m may even be resticted to as little as {0,1}, for example in binary encryption schemes.

Details

The scheme to use is determined by the public key which contains the parameter values for that scheme as part of it.

If a symmetric key scheme is being used, then the secret key should be provided for the pk argument.

Value

A ciphertext under the encryption scheme, encrypted using the public key provided.
