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.

RC4 is a symmetric cryptosystem, invented in 1987 by MIT cryptographer Ronald Rivest, who went on to found RSA Security. The algorithm has several known flaws, but it is still widely used. RC4 is also ...

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.

SSL/TLS encryption once again is being haunted by an outdated and weak feature long past its prime: a newly discovered attack exploits a weakness in the older, less secure RC4 encryption algorithm ...

Microsoft is officially moving to shut the door on RC4 - a legacy cryptographic cipher that has quietly persisted inside Windows authentication environments for decades - and forcing organizations to ...

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 patched serious vulnerabilities Tuesday in Windows, Internet Explorer and Office, but also urged customers to stop using the aging RC4 cipher and SHA-1 hashing function in their systems and ...

Sensor networks are expected to play an essential role in the upcoming age of pervasive computing. Due to their constraints in computation, memory, and power resources, their susceptibility to ...
