| SR-DIDs | BBS04-SR-DIDs | The scheme in reference [9] | |
|---|---|---|---|
| Supervisor key pair | 3|ℤp|+3|𝔾1|+1|𝔾2| | 3|ℤp|+3|𝔾1|+1|𝔾2| | 1|ℤp|+1|𝔾1|+1|𝔾2| |
| User key | 3|ℤp| + 1|𝔾1| | 3|ℤp| + 1|𝔾1| | 1|ℤp| |
| Identity identifier | 1|𝔾1| | 1|𝔾1| | 1|𝔾1| |
| Identity generation | 5|ℤp| + 5|𝔾1| | 6|ℤp| + 3|𝔾1| | 2k|ℤp| + 1|𝔾T| |
