A key component of the Gulf Stream has markedly slowed over the past century, influencing Earth's climate -- that's the conclusion of a new research paper in Nature Communications.The U.S. N...
Authentication with weaker trust assumptions for voting systems
voting systems cryptographic protocols
font style='font-size:12px;'>
2018/3/5
Some voting systems are reliant on external authentication services. Others use cryptography to implement their own. We combine digital signatures and non-interactive proofs to derive a generic constr...
A Linearly Homomorphic Signature Scheme From Weaker Assumptions
homomorphic signatures homomorphic encryption delegated computation
font style='font-size:12px;'>
2018/1/11
In delegated computing, prominent in the context of cloud computing, guaranteeing both the correctness and authenticity of computations is of critical importance. Homomorphic signatures can be used as...

If you pit a pair of gladiators, one strong and one weak, against each other 10 times, the outcome will likely be the same every time: The stronger competitor will defeat the weak. But if you add into...
Scalable Attribute-Based Encryption Under the Strictly Weaker Assumption Family
KP-ABE CP-ABE kk-BDH assumption family

2016/12/7
Attribute-Based Encryption (ABE) is a special type of public key encryption that allows users to share sensitive data efficiently through fine-grained access control. The security involved in existing...
Practical Round-Optimal Blind Signatures in the Standard Model from Weaker Assumptions

2016/6/29
At Crypto’15 Fuchsbauer, Hanser and Slamanig (FHS) presented the first standardmodel
construction of efficient round-optimal blind signatures that does not require complexity
leveraging. It is conce...
Verifiable Random Functions from Weaker Assumptions
Verifiable random functions q-type assumptions
font style='font-size:12px;'>
2016/1/6
The construction of a verifiable random function (VRF) with large input space and full adaptive security from a static, non-interactive complexity assumption, like decisional Diffie-Hellman, has prove...
The Sum Can Be Weaker Than Each Part
Hash functions combiners XOR combiner
font style='font-size:12px;'>
2016/1/4
In this paper we study the security of summing the outputs of two independent hash functions, in an effort to increase the security of the resulting design, or to hedge against the failure of one of t...
Multi-Input Functional Encryption in the Private-Key Setting: Stronger Security from Weaker Assumptions
font style='font-size:12px;'>
2016/1/4
We construct a general-purpose multi-input functional encryption scheme in the private-key
setting. Namely, we construct a scheme where a functional key corresponding to a function
f enables a user ...

font style='font-size:12px;'>
2012/3/28
We provide constructions of (m,1)-programmable hash functions (PHFs) for m >= 2. Mimicking certain programmability properties of random oracles, PHFs can, e.g., be plugged into the generic constructi...
