Web Secure Login Design With Symetric Encription RC-6 Algorithm [PDF]
, 2011 Authentication techniques that use at many web pages and easy to do is use user-id and password. However, these techniques are vulnerable to theft user-id and password when sent from client to server.

Remote-Sensing Image Encryption Algorithm Using the Advanced Encryption Standard
Applied Sciences, 2018 With the increasing use of multimedia in communications, the content security of remote-sensing images attracts much attention in both the academia and industry. The Advanced Encryption Standard (AES) is a famous symmetric cryptosystem.

Shared and Searchable Encrypted Data for Untrusted Servers [PDF]
, 2008 Current security mechanisms pose a risk for organisations that outsource their data management to untrusted servers. Encrypting and decrypting sensitive data at the client side is the normal approach in this situation but has high communication and ...

The Locality of Searchable Symmetric Encryption [PDF]
, 2014 This paper proves a lower bound on the trade-off between server storage size and the locality of memory accesses in searchable symmetric encryption (SSE). Namely, when encrypting an index of N identifier/keyword pairs, the encrypted index must have size ω(N) or the scheme must perform searching with ω(1) non-contiguous reads to memory or the scheme ...

On Symmetric Encryption and Point Obfuscation [PDF]
, 2010 We show tight connections between several cryptographic primitives, namely encryption with weakly random keys, encryption with key-dependent messages (KDM), and obfuscation of point functions with multi-bit output (which we call multi-bit point functions, or MBPFs, for short). These primitives, which have been studied mostly separately in recent works,

Order-Preserving Symmetric Encryption [PDF]
, 2009 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

Improved Banking XML Transaction Encryption Using Tag Fuzzy Classification [PDF]
In this paper we present a novel approach for securing financial XML transactions using intelligent fuzzy classification techniques. Given an XML message X, our approach defines the process of classifying XML content to assign a unique value, which ...
