A New Strategy for Finding a Differential Path of SHA-1
In this paper, we propose a new construction algorithm for finding differential paths of Round 1 of SHA-1 for use in the collision search attack. Generally, the differential path o...

Practical Compact E-Cash
Compact e-cash schemes allow a user to withdraw a wallet containing k coins in a single operation, each of which the user can spend unlinkably. One big open problem for compact e-c...

Efficient and Secure Comparison for On-Line Auctions
In this note, we describe a correction to the cryptosystem proposed in [1, 2]. Although the correction is small and does not affect the performance of the protocols from [1, 2], it...

Combining Prediction Hashing and MDS Codes for Efficient Multicast Stream Authentication
We study the multicast stream authentication problem when the communication channel is under control of an opponent who can drop, reorder and inject data packets. In this work, we...
