TLDR
A combination of asymmetric (public-key) and symmetric (secret- key) cryptography that allow two parties sharing a common password to exchange confidential and authenticated information over an insecure network is introduced.Abstract:
Classic cryptographic protocols based on user-chosen keys allow an attacker to mount password-guessing attacks. A combination of asymmetric (public-key) and symmetric (secret-key) cryptography that allow two parties sharing a common password to exchange confidential and authenticated information over an insecure network is introduced. In particular, a protocol relying on the counter-intuitive motion of using a secret key to encrypt a public key is presented. Such protocols are secure against active attacks, and have the property that the password is protected against offline dictionary attacks. >read more

On the security of some password-based key agreement schemes
Qiang Tang,Chris J. Mitchell +1 more
TL;DR: In this paper, the authors show that three potential security vulnerabilities exist in the strong password-only authenticated key exchange scheme due to Jablon and propose means to remove these security vulnerabilities.

TTP Based High-Efficient Multi-Key Exchange Protocol
TL;DR: The TTP-based high-efficient multi-key exchange protocol (THMEP), is proposed to provide users with a secure and efficient protocol, which employs the elliptic curve cryptography, a 2-D operation, and a current time encryption key, to exchange their session keys.

Secure Deduplication of Encrypted Data: Refined Model and New Constructions
TL;DR: Wang et al. as discussed by the authors proposed a formal security model for secure deduplication of encrypted data (SDoE) and proposed two single-server SDoE protocols and proved their security in their model.

A Computation-Efficient Three-Party Encrypted Key Exchange Protocol
TL;DR: This work proposes an efficient 3PEKE (L-3PEKE) scheme, which is more secure and efficient than other 3PEke protocols, and compares with other 3 PEKE protocols.

Official Arbitration with Secure Cloud Storage Application
TL;DR: It is argued that in such a case, both the client and the server should be able to contact an official court, providing cryptographic proofs, so that the Judge can resolve this dispute, and it is easy to extend the official arbitration protocols for a general case, including dynamic authenticated data structures.

A public key cryptosystem and a signature scheme based on discrete logarithms
TL;DR: A new signature scheme is proposed, together with an implementation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem that relies on the difficulty of computing discrete logarithms over finite fields.
