Abstract

A device for decrypting data includes a number of devices secured by at least one security device. The secured devices include a receiver for receiving calculation data encrypted using a homomorphic encryption function and a decryptor for decrypting the encrypted calculation data by carrying out the inverse of the homomorphic encryption function on the encrypted calculation data using a private key assigned to the homomorphic encryption function. A method and a computer program product for decrypting data are also provided.
