In PKC 1999, Fujisaki and Okamoto showed how to convert any public key encryption (PKE) scheme secure against chosen plaintext attacks (CPA) to a PKE scheme which is secure against...

We present new frameworks for constructing public-key encryption schemes satisfying key-dependent message (KDM) security and that yield efficient, universally composable oblivious...

We introduce delegatable functional signatures (DFS) which support the delegation of signing capabilities to another party, called the evaluator, with respect to a functionality F...

The well-known Signed ElGamal scheme consists of ElGamal encryption with a non-interactive Schnorr proof of knowledge. While this scheme should be intuitively secure against chosen...

We formally study “non-malleable functions” (NMFs), a general cryptographic primitive which simplifies and relaxes “non-malleable one-way/hash functions” (NMOWHFs) introd...
