چکیده

We present a variant of the Boneh & Franklin Identiybased Encryption IBE scheme to derive an authenticated symmetric key-exchange protocol, when combined with a signature scheme. Our protocol uses IBE as a secure channel to establish a symmetric key between two users and, after that, further communication can be done by symmetric cryptography, much faster than pairing-based cryptography.

Group Password-Authenticated Key Exchange from Identity-Based Cryptosystem

Password-authenticated key exchange (PAKE) protocols are designed to be secure even when the secret key used for authentication is a human-memorable password. In this paper, we consider PAKE protocols in the group scenario, in which a group of clients, each of them shares a password with an “honest but curious” server, intend to establish a common secret key (i.e., a group key) with the help of...

Threshold Password-based Authenticated Key Exchange using Matrix

Authentication protocols rely on the possession of keys by the parties to be authenticated. For security, keys must be chosen randomly and have to have a long length from 100 bits to thousands of bits. But such keys are difficult to memorize for humans. Password-based authenticated key exchange protocols offer an efficient method to achieve an authentication and a secure communication between t...

Encryptor Combiners: A Unified Approach to Multiparty NIKE, (H)IBE, and Broadcast Encryption

We define the concept of an encryptor combiner. Roughly, such a combiner takes as input n public keys for a public key encryption scheme, and produces a new combined public key. Anyone knowing a secret key for one of the input public keys can learn the secret key for the combined public key, but an outsider who just knows the input public keys (who can therefore compute the combined public key ...

On the leakage-resilient key exchange

Typically, secure channels are constructed from an authenticated key exchange (AKE) protocol,which authenticates the communicating parties based on long-term public keys and establishes secretsession keys. In this paper we address the partial leakage of long-term secret keys of key exchangeprotocol participants due to various side-channel attacks. Security models for two-party authe...
