Processing encrypted signals requires special properties of the underlying encryption
scheme. A possible choice is the use of homomorphic encryption. In this paper, we propose …

This paper shows a generic and simple conversion from weak asymmetric and symmetric
encryption schemes into an asymmetric encryption scheme which is secure in a very strong …

This paper presents a generic conversion from weak asymmetric and symmetric encryption
schemes to an asymmetric encryption scheme that is chosen-ciphertext secure in the …

Seven years after the optimal asymmetric encryption padding (OAEP) which makes chosen-
ciphertext secure encryption scheme from any trapdoor one-way permutation (but whose …

Data aggregation is an important method to reduce the energy consumption in wireless
sensor networks (WSNs), however, performing data aggregation while preserving data …

Traditional encryption is based on secrecy provided by secret-key. But this leads to
generation of same cipher text when the encryption scheme is applied to same plaintext with …

Thedemandforprivacyofdigitaldataandofalg… have increased exponentially over the last
decade. This goes in parallel with the growth in communication networks and theirdevices …

The growth of the Internet has created tremendous opportunities for online collaborations.
These often involve collaborative optimizations where the two parties are, for example …

This paper examines the methods in which the ideas behind a KEM--DEM hybrid encryption
scheme can be extended to other types of asymmetric primitives, particularly to signcryption …

In an open environment such as the Internet, the decision to collaborate with a stranger (eg,
by granting access to a resource) is often based on the characteristics (rather than the …
