Sequential and Parallel Cascaded Convolutional Encryption with Local Propagation: Toward Future Directions in Symmetric Cryptogr
Worldwide symmetric encryption standards such as DES (Data Encryption Standard), AES (Advanced Encryption Standard), and EES (Escrowed Encryption Standard), have been – and some...

A Service Framework based on Grades of IdPs and SPs
In Web services, a framework for the separation of authentication (IdP) and services (SP) has been proposed and actually deployed. In this framework, quality of information provide...

Strongly Unforgeable Signatures and Hierarchical Identity-Based Signatures from Lattices without Random Oracles
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

Some RSA-Based Encryption Schemes with Tight Security Reduction
In this paper, we study some RSA-based semantically secure encryption schemes (IND-CPA) in the standard model. We first derive the exactly tight one-wayness of Rabin-Paillier encr...

How Secure Are Elliptic Curves over Composite Extension Fields?
We compare the method of Weil descent for solving the ECDLP, over extensions fields of composite degree in characteristic two, against the standard method of parallelised Pollard ...
