Homomorphic encryption schemes are powerful cryptographic primitives that allow for a variety of applications. Consequently, a variety of proposals have been made in the recent decades but none of them was based on coding theory. The existence of such schemes would be interesting for several reasons. First, it is well known that having multiple schemes based on different hardness assumptions is advantageous. In case that one hardness assumption turns out be wrong, one can switch over to one of the alternatives. Second, for some codes decoding (which would represent decryption in this case) is a linear mapping only (if the error is known), i.e., a comparatively simple operation.
