Order-Preserving Incomplete Suffix Trees and Order-Preserving Indexes

Recently Kubica et al. (Inf. Process. Let., 2013) and Kim et al. (submitted to Theor. Comp. Sci.) introduced order-preserving pattern matching: for a given text the goal is to find its factors having the same “shape” as a given pattern. The known results include a linear-time algorithm for this problem (in case of polynomially-bounded alphabet) and a generalization to multiple patterns. We exte...

Optimal First-Order Masking with Linear and Non-linear Bijections

Hardware devices can be protected against side-channel attacks by introducing one randommask per sensitive variable. The computation throughout is unaltered if the shares (masked variable and mask) are processed concomitantly, in two distinct registers. Nonetheless, this setup can be attacked by a zero-offset second-order CPA attack. The countermeasure can be improved by manipulating the mask t...

Order Preserving Key Compression

Order preserving data compression can improve sorting and searching performance, and hence the performance of database systems. We describe a new parsing (tokenization) technique that can be effectively applied to "keys", producing substantial compression. It can be applied to both the uncompressed and compressed strings, permiting a more flexible choice of variable length dictionary entries an...

Order-Preserving Symmetric Encryption

We initiate the cryptographic study of order-preserving symmetric encryption (OPE), a primitive suggested in the database community by Agrawal et al. (SIGMOD ’04) for allowing efficient range queries on encrypted data. Interestingly, we first show that a straightforward relaxation of standard security notions for encryption such as indistinguishability against chosen-plaintext attack (IND-CPA) ...
