In this work, relations between the security notions standard simulatability and universal simulatability for cryptographic protocols are investigated. A simulatability-based notio...
Encryption of data using multiple, independent encryption schemes (“multiple encryption”) has been suggested in a variety of contexts, and can be used, for example, to protect ...
Abstract. We consider the problem of password-authenticated key exchange (PAK) also known as session-key generation using passwords: constructing session-key generation protocols t...
Definition of security under the framework of Environmental Security (a.k.a Network-Aware Security or Universally Composable Security) typically requires “extractability” of t...
Adaptively-secure encryption schemes ensure secrecy even in the presence of an adversary who can corrupt parties in an adaptive manner based on public keys, ciphertexts, and secret...
