Byun et al. suggested keyword guessing attacks and showed that some PEKS (public-key
encryption with keyword search) schemes are not secure to keyword guessing attacks, when …

As communication technology advances, various and heterogeneous data are communicated
in distributed environments through network systems. Meanwhile, along with the …

Many arbitrated quantum signature schemes implemented with the help of a trusted third
party have been developed up to now. In order to guarantee unconditional security, most of …

Traditional public key exchange protocols are based on algebraic number theory. In another
perspective, neural cryptography, which is based on neural networks, has been emerging. It …

The rectangle attack and the related-key attack on block ciphers are well-known to be very
powerful. In this paper we combine the rectangle attack with the related-key attack. Using this …

As the amount of data and computational power explosively increase, valuable results are
being created using machine learning techniques. In particular, models based on deep neural …

This paper presents a new bit-parallel multiplier for the finite field GF(2/sup m/) defined by
an irreducible all-one polynomial. In order to reduce the complexity of the multiplier, we …

Most of the provably-secure proxy signature schemes rely on the average-case hardness
problems such as the integer factorization problems and the discrete logarithm problems. …

The main property of the self-healing key distribution scheme is that users are capable of
recovering lost group keys on their own, without requesting additional transmission from the …

Privacy-preserving set operations such as set union and set intersection on distributed sets
are widely used in data mining in which the preservation of privacy is of the utmost concern. …
