Homomorphic Evaluation of Lattice-Based Symmetric Encryption Schemes
secret-key cryptography FHE
2018/7/9
Optimizing performance of Fully Homomorphic Encryption (FHE) is nowadays an active trend of research in cryptography. One way of improvement is to use a hybrid construction with a classical symmetric ...
Dynamic Searchable Symmetric Encryption Schemes Supporting Range Queries with Forward (and Backward) Security
Dynamic searchable symmetric encryption forward security backward security
2018/6/27
Dynamic searchable symmetric encryption (DSSE) is a useful cryptographic tool in the encrypted cloud storage. However, it has been reported that DSSE usually suffers from the file-injection attacks an...
White-Box Security Notions for Symmetric Encryption Schemes
White-Box Cryptography Security Notions
2014/3/10
White-box cryptography has attracted a growing interest from researchers in the last decade. Several white-box implementations of standard block-ciphers (DES, AES) have been proposed but they have all...
Security of Symmetric Encryption Schemes with One-Way IND-CNA Key Setup
Provable Security Stream Cipher Key Scheduling Algorithm
2009/3/27
We analyse the consequences of specific properties of the
key-setup phase in symmetric encryption schemes for their security. We
find that key-setup routines satisfying IND-CNA and one-wayness allow...
