Dynamic Searchable Symmetric Encryption with Forward and Stronger Backward Privacy
Dynamic Searchable Symmetric Encryption Forward Privacy Backward Privacy
<
2019/9/19
Dynamic Searchable Symmetric Encryption (DSSE) enables a client to perform updates and searches on encrypted data which makes it very useful in practice. To protect DSSE from the leakage of updates (l...
Security of Symmetric Primitives against Key-Correlated Attacks
Key-correlated attack related-key attack key-dependent-message attack
<
2019/9/5
We study the security of symmetric primitives against key-correlated attacks (KCA), whereby an adversary can arbitrarily correlate keys, messages, and ciphertexts. Security against KCA is required whe...
IoT-Friendly AKE: Forward Secrecy and Session Resumption Meet Symmetric-Key Cryptography

<
2019/8/13
With the rise of the Internet of Things and the growing popularity of constrained end-devices, several security protocols are widely deployed or strongly promoted (e.g., Sigfox, LoRaWAN, NB-IoT). Base...
Count of rotational symmetric bent Boolean functions
Rotational Symmetric Boolean Function Algebraic Normal Form Bent Boolean Function

2019/8/2
Counting the Boolean functions having specific cryptographic features is an interesting problem in combinatorics and cryptography. Count of bent functions for more than eight variables is unexplored. ...
Multi-Client Symmetric Searchable Encryption with Forward Privacy

2019/7/15
Symmetric Searchable encryption (SSE) is an encryption technique that allows users to search directly on their outsourced encrypted data, in a way that the privacy of both the files and the search que...
Scalable Private Set Union from Symmetric-Key Techniques
Private Set Union Private Membership Test
<
2019/7/4
We present a new efficient protocol for computing private set union (PSU). Here two semi-honest parties, each holding a dataset of known size (or of a known upper bound), wish to compute the union of ...

2019/6/12
Secure cloud storage is considered as one of the most important issues that both businesses and end-users take into account before moving their private data to the cloud. Lately, we have seen some int...
Securely managing encrypted data on an untrusted party is a challenging problem that has motivated the study of a variety of cryptographic primitives. A special class of such primitives allows an untr...
With this work, we intend on demonstrating the need for improvements to the currently standardized AES family of cryptosystems, and provide a solution that meets the requirements of long-term security...
Forward and Backward-Secure Range-Searchable Symmetric Encryption

<
2019/5/21
Dynamic searchable symmetric encryption (DSSE) allows a client to search or update over an outsourced encrypted database. Range query is commonly needed (AsiaCrypt'18) but order-preserving encryption ...
Improved Filter Permutators: Combining Symmetric Encryption Design, Boolean Functions, Low Complexity Cryptography, and Homomorphic Encryption, for Private Delegation of Computations
Filter Permutator FLIP Homomorphic Encryption
