Efficient provable-secure NTRUEncrypt over any cyclotomic field
NTRU Ideal lattice Canonical embedding
2017/11/20
NTRUEncrypt is a fast lattice-based cryptosystem and a probable alternative of the existing public key schemes. The existing provable-secure NTRUEncrypts are limited by the cyclotomic field it works o...
Efficient and Provable Secure Anonymous Hierarchical Identity-based Broadcast Encryption (HIBBE) Scheme without Random Oracle
Broadcast encryption Hierarchical identity-based encryption Identity-based multi designated verifier signature
2016/12/10
Hierarchical identity-based broadcast encryption (HIBBE) organizes the users in a tree-like structure in which they can delegate the decryption ability to their subordinates. In addition, the trusted ...
A provable secure anonymous proxy signature scheme without random oracles
public-key cryptography
2014/3/7
In order to protect the proxy signers’ privacy, many anonymous proxy signature schemes which are also called proxy ring signatures, have been proposed. Although the provable security in the random ora...
Network coding allows the routers to mix the received information before forwarding them
to the next nodes. Though this information mixing has been proven to maximize network
throughput, it also int...
Generalized signcryption which proposed by Han is a new
cryptographic primitive which can work as an encryption scheme, a signature
scheme or a signcryption scheme [5]. However,the security proof
i...
