This paper examines the security of AES-192 and AES-256 against a related-key rectangle attack. We find the following new attacks: 8-round reduced AES-192 with 2 related keys, 10-...
Poly1305-AES is a state-of-the-art message-authentication code suitable for a wide variety of applications. Poly1305-AES computes a 16-byte authenticator of a variable-length messa...
In this paper we study the substitution-permutation network (SPN) on which AES is based. We introduce AES∗ , a SPN identical to AES except that fixed S-boxes are replaced by ran...
