Unbalanced Identity-Based Key Agreement With Identity PrivacyIdentity-Based Key Agreement • March 16th, 2006
Abstract. On AisaCrypt 2005 Barreto et al. proposed an elegant identity- based signcryption scheme built from pairings. By using this scheme as the main ingredient, we present a suit of identity-based key agreements, which not only achieve strong security, but also have unbalanced compu- tation complexity and identity privacy. Furthermore, the protocols are also equipped to mitigate the threat of Denial-of-Service attacks. These make the protocols particularly suitable for certain applications, such as authentication in mobile networks with low power devices.
Abstract—In the new paradigm of blockchain-powered intel- ligent edge, the key agreement is a significant problem which has not been extensively studied so far. Existing key agreement protocols in the traditional public-key setting are usually too...Identity-Based Key Agreement • September 7th, 2021
This paper designs and realizes two novel ID-based key agreement protocols for the blockchain-powered intelligent edge, including an extended Canetti-Krawczyk (eCK) secure ID-based authenticated key agreement (AKA) protocol and a continuous after-the-fact leakage-resilient eCK (CAFL-eCK) secure ID-based AKA protocol. Both protocols do not involve any heavy pairing computation. Besides, the second one can resist side-channel attacks to the KGC and the communicating parties. A hybrid implementation of the two protocols can achieve high efficiency and strong security at the same time in blockchain-powered intelligent edge environments. This is demonstrated via a use case of a blockchain-powered smart home.
