| 标题： | [SEETF 2023]No Subbox |
| 描述： | Don't you hate SBOXes? They are clunky, fragile, and liable to cache timing attacks. Well, I've fixed it by removing SBOXes and replacing all operations with a non-abelian group operation! You can't do linear cryptanalysis when the cipher has nothing linear about it! 得到的flag请使用NSSCTF{}格式提交。 |
