A fresh warning concerning the use of RC4 to support secure communication channels online has been issued after researchers were able to exploit the protocol to decrypt user data in mere hours.

Abstract: RC4 algorithm is a famous stream cipher. It could be used to encrypt images quickly and efficient. However, the RC4 has been proved has some drawbacks, therefore it is considered not secure ...

RC4 is a stream cipher and variable-length key algorithm. This algorithm encrypts one byte at a time (or larger units at a time). A key input is a pseudorandom bit generator that produces a stream ...

The RC4 and SHA-1 algorithms have taken a lot of hits in recent years, with new attacks popping up on a regular basis. Many security experts and cryptographers have been recommending that vendors ...

Abstract: Wireless Local Area (WLAN) has become a hot spot of application in the field of telecommunication these years. To secure WLAN for data transmission, RC4 algorithm is able to provide the ...

There’s an old saying in the security community: Attacks always get better. The latest case where that holds true is for the aging RC4 cipher that’s still widely used to encrypt communications on the ...

Microsoft released optional security updates Tuesday for various versions of the .NET Framework that prevent the RC4 encryption algorithm from being used in TLS (Transport Layer Security) connections.

Microsoft issued advisories informing users they can now disable RC4 in .NET, in addition to additional credential protection for Windows and that it had revoked digital signatures for four UEFI ...

Despite claims that the problem lies in how Microsoft implements Kerberos in Windows, standard best practices and hardening rules can stop Golden Ticket and Pass-the-Hash attacks It’s hard enough ...
