Universal Forgery and Key Recovery Attacks on ELmD Authenticated Encryption Algorithm
Explore a comprehensive analysis of security vulnerabilities in the ELmD authenticated encryption algorithm through this 24-minute conference talk presented at Asiacrypt 2016. Delve into the differences between encryption and authenticated encryption, examine the CAESAR competition submissions, and understand the linear mixing function and message padding rules. Investigate the processing of associated data and security claims before uncovering techniques for recovering internal state L and executing universal forgery attacks. Learn how to exploit the structure of ELmD, query the decryption oracle of AES, and perform key recovery attacks on ElmD(6.6). Compare these findings with previous results and draw important conclusions about the algorithm's security.
