Explore a presentation from WAC 2020 examining cache attacks on CTR_DRBG, a standardized pseudorandom number generator. Delve into the design flaws of CTR_DRBG, including key rotation issues and lack of entropy. Investigate the feasibility of side-channel attacks on this generator and their implications for TLS handshakes. Analyze attack scenarios targeting TLS 1.2 RSA key exchange with client authentication, and examine state recovery techniques. Study the differential structure of AES internal states and learn about experimental setups for interrupting SGX execution. Gain insights into the complexities of cryptographic implementations and the importance of robust security measures in standardized designs.
