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...
