Weaknesses of a Password-Authenticated Key Exchange Protocol between Clients with Different Passwords
A password-authenticated key exchange scheme allows two entities, who only share a memorable password, to authenticate each other and to agree on a cryptographic session key. Instead of considering it in the c...

Strengthening Password-Based Authentication Protocols Against Online Dictionary Attacks
Passwords are one of the most common cause of system break-ins, because the low entropy of passwords makes systems vulnerable to brute force guessing attacks (dictionary attacks). Existing Strong Password-base...

An Improved Poly1305 MAC
In this paper, we propose an improved Poly1305 MAC, called IPMAC. IPMAC is a refinement of Poly1305 MAC shown by Bernstein. We use only one 16-byte key and one 16-byte nonce for IPMAC while Poly1305 MAC uses t...

Real Perfect Contrast Visual Secret Sharing Schemes with Reversing
The visual secret sharing (VSS for short) scheme is a secret image sharing scheme. A secret image is visually revealed from overlap** shadow images without additional computations. However, the contrast of r...

The Delicate Issues of Addition with Respect to XOR Differences
In this paper we analyze the previous attacks on the block cipher SHACAL-1 and show that all the differential-based attacks fail due to mistreatment of XOR differences through addition. We show that the previo...
