Security in the Presence of Key Reuse: Context-Separable Interfaces and their Applications
Key-reuse APIs Diffie-Hellman EdDSA
2019/5/21
Key separation is often difficult to enforce in practice. While key reuse can be catastrophic for security, we know of a number of cryptographic schemes for which it is provably safe. But existing for...
Separable Statistics and Multidimensional Linear Cryptanalysis
block ciphers multidimensional linear cryptanalysis separable statistics
2017/10/12
Multidimensional linear cryptanalysis of block ciphers is improved in this work by introducing a number of new ideas. Firstly, formulae is given to compute approximate multidimensional distributions o...

Comparison Between Irreducible and Separable Goppa Code in McEliece Cryptosystem
McEliece cryptosystem Goppa code separable irreducible
2015/12/21
The McEliece cryptosystem is an asymmetric type of cryptography based on
error correction code. The classical McEliece used irreducible binary Goppa code which
considered unbreakable until now espec...

Let A be an algebra over a field k. If M is an A–bimodule, we let
MA and MA denote respectively the k–spaces of invariants and coinvariants of
M, and 'M : MA

Robust efficient frontier analysis with a separable uncertainty model
The mean - variance model effective portfolio construction model parameters return on assets uncertainty analysis and numerical examples
2015/8/10
Mean-variance (MV) analysis is often sensitive to model mis-specification or uncertainty, meaning that the MV efficient portfolios constructed with an estimate of the model parameters (i.e., the expec...
