| Abstract: | Based on the fully homomorphic encryption DGHV scheme proposed by Gentry et al.in EUROCRYPT 2010 and the technology of batch,this paper presented a homomorphic evaluation method of lightweight block cipher SIMON circuit by state-wise bitslicing,and proposed a representation called half-byte-wise bitslicing.On this basis,this paper provided the implementation method of half-byte-wise bitslicing homomorphic evaluation of PRINCE circuit.Lastly,this paper compared PRINCE,SIMON-64/128,SIMON-128/256 with AES-128 with respect to the homomorphic operations,and analyzed the counts of homomorphic evaluation of different block cipher circuits and different implementation methods. |
