Lattice-based verifiably encrypted group signatures
CybersecurityVerifiably encrypted signature (VES) schemes are extensively utilized in fair exchange which combine the features of encryption and signature, aiming to provide a solution that can not only verify the validity of signatures but also safeguard the privacy

A Proxy Re-Encryption Scheme with the Unforgeability of Re-Encryption Keys against Collusion Attacks [PDF]
, 2014 Proxy re-encryption (PRE) schemes are cryptosystems which allow a proxy who has a re-encryption key to convert a ciphertext originally encrypted for one party into a ciphertext which can be decrypted by another party. In [1], Hayashi et al.

Attribute-based alterable threshold ring signature scheme with conspiracy attack immunity
Tongxin xuebao, 2015 Attribute-based cryptography is a generalization and development of the identity-based cryptography,which extends the identity to a set of attributes.In the attribute-based cryptosystem,different members with the same attributes can form a signature ring

Scheme on user identity attribute preserving based on ring signcryption for cloud computing
Tongxin xuebao, 2014 Identity attribute leak as the most severe security threat of cloud computing,in order to solve this problem,a protection scheme of identity attributes based on ring signcryption was proposed.Focused on digital identity management in cloud service,which ...

Proxying Is Enough: Security of Proxying in TLS Oracles and AEAD Context Unforgeability [PDF]
TLS allows a client to securely obtain data from a server, but does not allow the client to offer the data provenance to an external node. TLS oracle protocols are used to solve the problem.
