Triple receiver public key encryption cryptosystem
A triple receiver public key cryptosystem was proposed. In the cryptosystem, a sender encrypted a message and sent to three receivers, while the three receivers were able to decrypt the message with their own private keys.

Revocable identity‐based matchmaking encryption in the standard model
Identity‐based Matchmaking Encryption (IB‐ME) is an extension notion of matchmaking encryption (CRYPTO 2019), where a sender and a receiver can specify an access policy for the other party.

Searchable Attribute-Based Signcryption Scheme for Electronic Personal Health Record
Considering the scenario of an electronic personal health record system, we put forward a new cryptographic concept called searchable attribute-based signcryption, which can support fine-grained access control, data privacy, data authenticity, and data ...

An Identity-based Signature Scheme with CDH Problem Security [PDF]
Tight security proofs need shorter security parameters and better efficiency.Therefor,a new Identity-based Signature(IBS) scheme named IDSSTR is proposed,which has a security specification for Computational Diffie-Hellman(CDH) problems and it is also ...

A Security-Mediated Encryption Scheme Based on ElGamal Variant
Boneh et al. introduced mediated RSA (mRSA) in 2001 in an attempt to achieve faster key revocation for medium-sized organizations via the involvement of a security mediator (SEM) as a semi-trusted third party to provide partial ciphertext decryption for ...

Two-way and anonymous heterogeneous signcryption scheme between PKI and IBC
Exiting heterogeneous signcryption schemes which were between public key infrastructure (PKI) and identity-based cryptosystem (IBC) have some limitations.A new heterogeneous signcryption scheme between PKI and IBC was proposed.In the random oracle mode ...
