Ciphers with identical round keys Ciphers like PRINCE or LED seem to use identical round keys. Does anybody know other cipher (may include hash functions, MACs or AEADs) that has the same property?
LED and prince ciphers are designed for lightweight purpose (to save area, energy..etc) , They have no key schedule. Other ciphers that have no key schedule are Zorro, Midori, LS-designs (Fantomas &amp; Robin).
The above mentioned ciphers use round constant addition for protection.
