Offline Witness Encryption with Semi-adaptive Securitylarly interesting variant is Offline WE (OWE) by Abusalah et al. (ACNS 2016), as the encryption algorithm uses neither obfuscation nor multilinear maps..Current OWE schemes provide only . security. That is, the adversary must commit to their challenge messages . and . . seeing the public parameters.

Efficient Anonymous Multi-group Broadcast Encryptionly, conventional broadcast encryption schemes are deemed unsuitable for such platforms since they generate an independent ciphertext for each piece of contents and hence the number of headers generated during encryption increases linearly with the size of contents. The increased number of headers wi

Improving the Efficiency of Re-randomizable and Replayable CCA Secure Public Key Encryption and non-malleability properties: ciphertexts can be re-randomized (and thus made unlinkable) while still retaining the important security guarantee that the message inside stays intact..In this paper we show a new public-key encryption scheme that is Rand-RCCA secure in the random oracle model.

Autonomous Control Approach for Local Searchcation code, etc. One popular approach of designing tweakable block ciphers is to tweak the generic constructions of classic block ciphers. This paper focuses on how to build a secure tweakable block cipher from the Key-Alternating Feistel (KAF) structure, a dedicated Feistel structure with round fu
