A Partial Homomorphic encrytion technique for encrypted and unncrypted computation

Computer Engineering

we introduce Cryptoleq: associate abstract machine supported the construct of Instruction Set laptop, capable of activity general computation on encrypted programs. The program operands area unit protected victimisation the Paillier part homomorphic cryptosystem, which supports addition on the encrypted domain. Full homomorphy over addition and multiplication, that is critical for enabling general computation, is achieved by inventing a heuristically obfuscated software system re-encryption module written using Cryptoleq directions and integrated into the death penalty program. Cryptoleq is heterogeneous, permitting compounding encrypted and unencrypted instruction operands within the same program memory area. Programming with Cryptoleq is expedited victimization an increased programing language that enables development of associate advanced algorithmic program on encrypted datasets. In our analysis, we compare Cryptoleq’s performance against a popular absolutely homomorphic cryptography library, and demonstrate correctness using a typical personal info Retrieval drawback.
