| Sep 5, 2018 at 4:18 | comment | added | crypt | what about related key attack? cipher without a keyschedule will need more rounds to be secure under related key attack as compare to cipher with the key schedule. if you are familiar with AES operations, then see LED block cipher, it does not employ key schedule and its specification document provide proof against related key attack but with 32 and 48 rounds as compare to 10 and 14 rounds of AES | |
