Researchers at the University of Maryland, Baltimore County have developed a technique for quicker analysis of extensive data from Arctic ice sheets to gain knowledge of patterns and trends.Over the y...
Vectorized linear approximations for attacks on SNOW 3G
SNOW 3G Stream Cipher 5G Mobile System Security
2019/9/3
SNOW 3G is a stream cipher designed in 2006 by ETSI/SAGE, serving in 3GPP as one of the standard algorithms for data confidentiality and integrity protection. It is also included in the 4G LTE standar...
Security Evaluation for Snow 2.0-like Stream Ciphers Against Correlation Attacks over Extension Fields
symmetric cryptography stream cipher correlation attack
2019/3/20
We propose a general method for security evaluation of SNOW 2.0-like ciphers against correlation attacks that are built similarly to known attacks on SNOW 2.0. Unlike previously known methods, the met...
In this paper we are proposing a new member in the SNOW family of stream ciphers, called SNOW-V. The motivation is to meet an industry demand of very high speed encryption in a virtualized environment...
