Program obfuscation

A cryptographic master tool called indistinguishability obfuscation has for years seemed too good to be true. Three researchers have figured out that it can work.

A recent cryptographic breakthrough has proven difficult to put into practice. But new advances show how near-perfect computer security might be surprisingly close at hand.

In a watershed moment for cryptography, computer scientists have proposed a solution to a fundamental problem called “program obfuscation.”
