Table 1 The comparison between Canetti et al.’s scheme and our scheme
Scheme | Secret key | Number of computation for addition | Number of computation for multiplication |
|---|---|---|---|
Canetti et al.’s Scheme | An obfuscation of | t | t2+t |
| Â | some decryption circuit | Â | Â |
Our Scheme | The secret key of a trapdoor encryption scheme | 1 | 1 |
