Abstract The beautiful work of Applebaum, Ishai, and Kushilevitz [FOCS’11] initiated the study of arithmetic variants of Yao’s garbled circuits. An arithmetic garbling scheme is an effi- cient transformation that converts an arithmetic circuit C over a ring R into a garbled circuit C' and an affine functions Li for each input bit xi, such that C' and Li(xi) reveals only the output C(x) and no other information of x. AIK presented the first arithmetic garbling scheme supporting computation over integers from a bounded (possibly exponentially large) range, based on Learning With Errors…
