Identity-Set-based Broadcast Encryption supporting “Cut-or-Select” with Short Ciphertext
Broadcast Encryption Cryptographic Membership Aggregation Function
2015/12/31
In this paper we present an identity-set-based broadcast encryption scheme with three working modes: positive membership (Select-mode), all member (All-mode), and negative membership (Cut-mode) over t...
Chosen ciphertext secure public key encryption under DDH assumption with short ciphertext
public key encryption IND-CCA2 DDH
2009/6/5
An efficient variant of the ElGamal public key encryption scheme is proposed which is
provably secure against adaptive chosen ciphertext attacks(IND-CCA2) under the decisional Diffie-
Hellman(DDH) a...
Efficient chosen ciphertext secure PKE scheme with short ciphertext
PKE DHIES tag-KEM IND-PA
2008/8/25
Kurosawa and Matsuo[1] showed that MAC can be removed from DHIES while the underlying
symmetric-key encryption(SKE) scheme is secure against adaptive chosen ciphertext attacks(INDCCA).We construct a ...
