Efficient Self-certified Signatures with Batch Verification,nly one modular multiplication in signing with pre-computation. One of features of our scheme lies in its batch verification in both single-signer and multi-signer settings. Pairing computations in the batch verification are independent from the number of signatures. Our scheme is proven secure in the random oracle model.

FISC

Weak-Key Class of MISTY1 for Related-Key Differential Attack, under the weak-key class, which lead to the attacks on the 8-round MISTY1 without the first . lay. The attack requires 2. chosen ciphertexts, and the time complexities is 2.. To the best of our knowledge, the attack reported in this paper is the most powerful attack against MISTY1 with two related keys.

Improved Tradeoff between Encapsulation and Decapsulation of HK09,We propose a new variant of HK09 (Proposed by Hofheinz and Kiltz in Eurocrypt2009) which simplifies the decapsulation. Our result is a tradeoff between the efficiency of encapsulation and decapsulation. Compared with original HK09 the efficiency of decapsulation is improved by 38.9% and the efficiency of encapsulation is dropped by 11.4%.

Cryptanalysis vs. Provable Security,aring cryptanalysis results and provable security results on a variety of topics. We argue that security is complex, and that there is much to gain from better interaction between cryptanalysis and provable security.
