The Meet-in-the-Middle (MitM) attack has been widely applied to preimage attacks on Merkle-Damgård (MD) hashing. In this paper, we introduce a generic framework of the MitM sponge-based We find certain bit conditions can significantly reduce diffusion unknown bits and lead longer characteristics. To good or optimal configurations attacks, e.g., conditions, neutral sets, matching points, bit-lev...

Key establishment is one fundamental issue in wireless security. The widely used Diffie-Hellman key exchange vulnerable to the man-in-the-middle (MITM) attack due its lack of mutual authentication. This paper presents a novel in-band solution for defending MITM during process devices. Our based on insight that an attacker inevitably affects link layer behavior channel, and this change introduce...

The security of the post-quantum signature scheme Picnic is highly related to difficulty recovering secret key LowMC from a single plaintext-ciphertext pair. Since one alternate third-round candidates in NIST cryptography standardization process, it has become urgent and important evaluate setting. best attacks on with full S-box layers used Picnic3 were achieved Dinur’s algorithm. For partial ...

A Domain Name Server is a critical Internet component. It enables users to surf the web and send emails. DNS database used by millions ofcomputers determine which address best answers user’s query. an unencrypted protocol that may be exploited in numerous ways. The mostpopular MITM attack uses poisoning intercept communications fake them. servers do not verify IP addresses they forwardtraffic t...

When browsing the web using HTTPS, if a user Alice ignores, or clicks through, the browser’s SSL warnings of an invalid SSL certificate, she exposes her browser sessions to a Man-in-the-middle (MITM) attack, allowing attackers to intercept communication in the SSL channel. Recent work has measured the click-through rates for SSL warnings, indicating that more than 50% users click through SSL wa...

More and more Internet traffic is encrypted. While this protects the confidentiality integrity of communication, it prevents network monitoring systems (NMS) from effectively analyzing now encrypted payloads. Many enterprise networks have deployed man-in-the-middle (MitM) proxies that intercept TLS connections at border to examine packet payloads regain visibility. However, interception via Mit...

Man-in-the-middle (MITM) attacks pose a serious threat to SSL/TLS-based e-commerce applications, such as Internet banking. SSL/TLS session-aware user authentication can be used to mitigate the risks and to protect users against MITM attacks in an SSL/TLS setting. In this paper, we further delve into SSL/TLS session-aware user authentication and possibilities to implement it. More specifically, ...

This paper presents ongoing work towards extensions of meetin-the-middle (MITM) attacks on block ciphers. Exploring developments in MITM attacks in hash analysis such as: (i) the splice-and-cut technique; (ii) the indirect-partial-matching technique. Our first contribution is that we show corrections to previous cryptanalysis and point out that the key schedule is more vulnerable to MITM attack...

The technical improvements in modern power systems by the use of smart sensors, meters, multi-direction communication networks, and computers have given birth to cyber-physical grid networks. Any attack on is a threat grid's operation data collected from it. Therefore, security this diverse network primary concern. Two attacks tested paper are: Denial Service (DoS) Man In Middle (MITM). Remote ...

Recently, several mobile applications were released that claim to provide secure Voice-over-IP communications. Most of these, e.g., Redphone by Open WhisperSystems or Silent Phone by Silent Circle, are utilizing ZRTP [4] to establish session keys for end-to-end security. ZRTP was designed to achieve key exchange without trusted third parties or certificate infrastructure, while providing a way ...
