Abstract. We study the provable security of identity-based (ID-based) key agreement protocols. Although several published protocols have been proven secure in the random oracle mod...

In this paper, we propose an efficient multi-receiver identity based signcryption scheme which only needs one pairing computation to signcrypt a message for n receivers and can pro...

We identify and fill some gaps with regard to consistency (the extent to which false positives are produced) for public-key encryption with keyword search (PEKS), providing new de...

While recent timed-release encryption (TRE) schemes are implicitly supported by a certificateless encryption (CLE) mechanism, the security models of CLE and TRE differ and there is...
