Vinod Vaikuntanathan, the 'V' in [GVW14], talks about homomorphic trapdoor functions in his presentation talk Lattices and Cryptography: A Match Made in Heaven at PQCrypto 2014. HTDFs start at 23:32. The embedded video starts there, but you may want to rewind to the beginning to watch the entire, very inspiring, talk:
