RADIUS Insecurity RADIUS is almost thirty years old, and uses cryptography based on MD5. Given that MD5 has been broken for over a decade, what are the implications for RADIUS? Why is RADIUS still using MD5? RADIUS sti... IETF and RADIUS Standards
Announcing SRADIUS RADIUS has used MD5 for security for almost thirty years. It is time to use a modern alternative: SRADIUS! We just released an Internet-Draft which defines “Secure RADIUS”, or “SRADIUS”. We also have ... IETF and RADIUS Standards
Introducing RADIUS 1.1 RADIUS has a problem. The name of the problem is MD5. The MD5 hash algorithm was defined in 1991, and was used in RADIUS in 1993. However, MD5 is no longer secure. It is a bit of a miracle that RADIUS... IETF and RADIUS Standards
