Super-Strong RKA Secure MAC, PKE and SE from Tag-based Hash Proof System
related-key attack hash proof system message authentication code
2016/12/7
In this paper, we define new RKA security notions for several cryptographic primitives including message authentication code (MAC), public-key encryption (PKE) and symmetric encryption (SE). This new ...
A Tag Based Encoding: An Efficient Encoding for Predicate Encoding in Prime Order Groups
encodings prime order groups inner product encryption
2016/6/29
We introduce a tag based encoding, a new generic framework for
modular design of Predicate Encryption (PE) schemes in prime order groups. Our
framework is equipped with a compiler which is adaptivel...
Efficient Distributed Tag-Based Encryption and its Application to Group Signatures with Efficient Distributed Traceability
Group signatures distributed traceability distributed public-key encryption
2016/1/6
In this work, we first formalize the notion of dynamic group signatures with distributed traceability,
where the capability to trace signatures is distributed among n managers without requiring any i...
The development of tag-based cooperation via a socially acquired trait
Self-similarity Child development Cross-cultural Accent Brazil
2015/4/24
Recent theoretical models have demonstrated that phenotypic traits can support the non-random assortment of cooperators in a population, thereby permitting the evolution of cooperation. In these “tagb...
Recent game-theoretic simulation and analytical models have demonstrated that cooperative strategies mediated by indicators of cooperative potential, or “tags,” can invade, spread, and resist invasion...
