Constructing Confidential Channels from Authenticated Channels - Public-Key Encryption Revisited
The security of public-key encryption (PKE), a widely-used cryptographic primitive, has received much attention in the cryptology literature. Many security notions for PKE have been proposed, including several versions of CPA-security, CCA-security, and non-malleability. These security notions are usually defined via a game that no efficient adversary can win with non-negligible probability or ...
متن کاملAuthenticated Interleaved Encryption and its Application to Wireless Sensor Networks
We present AIE (Authenticated Interleaved Encryption), a new scheme that allows nodes of a network to exchange messages securely (i.e. encrypted and authenticated) without sharing a common key or using public key cryptography. Our scheme is well adapted to networks, such as ad hoc, overlay or sensor networks, where nodes have limited capabilities and can share only a small number of symmetric k...
متن کاملThe Hummingbird-2 Lightweight Authenticated Encryption Algorithm
Hummingbird-2 is an encryption algorithm with a 128-bit secret key and a 64-bit initialization vector. Hummingbird-2 optionally produces an authentication tag for each message processed. Like it’s predecessor Hummingbird-1, Hummingbird-2 has been targeted for low-end microcontrollers and for hardware implementation in lightweight devices such as RFID tags and wireless sensors. Compared to the p...
متن کاملπ-Cipher: Authenticated Encryption for Big Data
In today’s world of big data and rapidly increasing telecommunications, using secure cryptographic primitives that are parallelizable and incremental is becoming ever more important design goal. π-Cipher is parallel, incremental, nonce based authenticated encryption cipher with associated data. It is designed with the special purpose of providing confidentiality and integrity for big data in tr...
