Boosting Authenticated Encryption Robustness With Minimal Modifications
authenticated encryption robust AES
2017/3/13
Secure and highly efficient authenticated encryption (AE) algorithms which achieve data confidentiality and authenticity in the symmetric-key setting have existed for well over a decade. By all conven...
Universal Obfuscation and Witness Encryption: Boosting Correctness and Combining Security
Indistinguishability Obfuscation Witness Encryption Combiners
2016/3/14
Over the last few years a new breed of cryptographic primitives has arisen: on one hand they have previously unimagined utility and on the other hand they are not based on simple to state and tried ou...
Boosting Linearly-Homomorphic Encryption to Evaluate Degree-2 Functions on Encrypted Data
public-key cryptography homomorphic encryption
2016/1/6
We show a technique to transform a linearly-homomorphic encryption into a homomorphic
encryption scheme capable of evaluating degree-2 computations on ciphertexts. Our transformation is
surprisingly...
Boosting Higher-Order Correlation Attacks by Dimensionality Reduction
Dimensionality Reduction Higher-Order Correlation
2016/1/5
Multi-variate side-channel attacks allow to break higher-order masking
protections by combining several leakage samples. But how to optimally extract all
the information contained in all possible d-...
Boosting OMD for Almost Free Authentication of Associated Data
Authenticated encryption OMD associated data
2015/12/31
We propose pure OMD (p-OMD) as a new variant of the Offset Merkle-Damgård (OMD) authenticated
encryption scheme. Our new scheme inherits all desirable security features of OMD while having
a m...
