New Blast-RADIUS attack breaks 30-year-old protocol used in networks everywhere
What is the RADIUS protocol primarily used for?
The RADIUS protocol is primarily used for providing centralized authentication, authorization, and accounting management for users who connect and use a network service. It is a networking protocol that enables remote access servers to communicate with a central server to authenticate dial-in users and authorize their access to the requested system or service6.
When was the RADIUS protocol officially standardized?
The RADIUS protocol was officially standardized in 1997 by the Internet Engineering Task Force (IETF).
What vulnerabilities exist in the MD5 hash function?
MD5 hash function is vulnerable to collision attacks, where two different inputs produce the same hash value. This poses a severe security risk, particularly in applications like digital signatures. Additionally, MD5 is susceptible to preimage attacks, where attackers can reverse-engineer the hash to find an input that matches a given MD5 hash, compromising data security3. The speed at which MD5 can generate hashes also makes it susceptible to brute force attacks.
