White-Box Cryptography (#5590) (30x98)

Air date: Dec 29, 2013

Speaker: Dmitry Khovratovich Survey The goal of white-box cryptography is to protect cryptographic keys in a public implementation of encryption algorithms, primarily in the context of Pay-TV and tamper-resistant software. I present an overview of the white-box cryptography concept along with the most common applications and proposed designs. I discuss the subtle difference between white-box cryptography, public-key cryptography, and obfuscation.
