Nonmalleable Cryptography

SIAM Journal on Computing, 1991
The property of nonmalleability for the encryption function \(E\) is a stronger extension of the classic notion of semantic security that was introduced by Goldwasser and Micali. This property is defined as follows. For all polynomial-time computable relations \(R\) seeing \(\alpha\in E(x)\) does not help one to find \(\beta\in E(y)\), \(\beta\neq ...

Threshold Cryptography

European Transactions on Telecommunications, 1994
AbstractIn the traditional scenario in cryptography there is one sender, one receiver and an active or passive eavesdropper who is an opponent. Large bank transactions require two people to sign, implying two senders. So the power to generate a valid transaction is shared.

Scientific American
The science of cryptography lies at the very foundations of trust in current and future systems and devices for communication and computation. For example, secure communications over the internet today are possible thanks to mathematical work in cryptography in the 1970s and 80s.
