Message Authentication (MAC) Algorithm For The VMPC-R (RC4-like) Stream Cipher
stream cipher RC4 VMPC-R
2019/1/18
We propose an authenticated encryption scheme for the VMPC-R stream cipher. VMPC-R is an RC4-like algorithm proposed in 2013. It was created in a challenge to find a bias-free cipher within the RC4 de...
Statistical weaknesses in 20 RC4-like algorithms and (probably) the simplest algorithm free from these weaknesses - VMPC-R
PRNG CSPRNG RC4
2016/1/23
We find statistical weaknesses in 20 RC4-like algorithms including the original RC4, RC4A, PC-RC4 and others. This is achieved using a simple statistical test. We found only one algorithm which was ...
Statistical weakness in Spritz against VMPC-R: in search for the RC4 replacement
PRNG CSPRNG Spritz
2016/1/5
We found a statistical weakness in the Spritz algorithm designed by Ronald L. Rivest
and Jacob C. N. Schuldt. For N = 8: P rob(output(x) = output(x + 2)) = 1/N + 0.000498. The
bias becomes statistic...
VMPC-R Cryptographically Secure Pseudo-Random Number Generator Alternative to RC4
stream cipher distinguishing attack
2014/3/6
We present a new Cryptographically Secure Pseudo-Random Number Generator. It uses permutations as its internal state, similarly to the RC4 stream cipher. We describe a statistical test which revealed ...

VMPC Stream Cipher
2009/4/10
The VMPC Stream Cipher is a simple
encryption algorithm, designed as a proposed practical
application of the VMPC one-way function. The
general structure of the Cipher is based on an internal

VMPC One-Way Function
VMPC One-Way Function
2009/4/9
The VMPC function is a combination of
two basic operations – permutation composition and
integer addition. The function resulting from this
combination shows to have very high resistance to
invert...
VMPC-MAC: A Stream Cipher Based Authenticated Encryption Scheme
Authenticated Encryption MAC Stream Cipher
2009/4/1
A stream cipher based algorithm for computing Message Au-
thentication Codes is described. The algorithm employs the internal
state of the underlying cipher to minimize the required additional-to-
...
Two Linear Distinguishing Attacks on VMPC and RC4A and Weakness of RC4 Family of Stream Ciphers
RC4 VMPC RC4A cryptanalysis linear distinguishing attack
2008/9/11
1 At FSE 2004 two new stream ciphers VMPC and RC4A have been proposed.
VMPC is a generalisation of the stream cipher RC4, whereas RC4A is an attempt to increase
the security of RC4 by introducing an...
