Lower Bounds on Signatures From Symmetric Primitives
We show that every construction of one-time signature schemes from a random oracle achieves black-box security at most 2(1+o(1))q , where q is the total number of oracle queries a...

Generic Attacks on Unbalanced Feistel Schemes with Expanding Functions
Unbalanced Feistel schemes with expanding functions are used to construct pseudo-random permutations from kn bits to kn bits by using random functions from n bits to (k − 1)n bit...

Related-Key Rectangle Attacks on Reduced AES-192 and AES-256
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-...

The Security of the Extended Codebook (XCB) Mode of Operation
Abstract. The XCB mode of operation was outlined in 2004 as a contribution to the IEEE Security in Storage effort, but no security analysis was provided. In this paper, we provide...
