Cryptanalysis on HMAC/NMAC-MD5 and MD5-MAC [PDF]

Lecture Notes in Computer Science, 2009
In this paper, we present the first distinguishing attack on HMAC and NMAC based on MD5 without related keys, which distinguishes the HMAC/NMAC-MD5 from HMAC/NMAC with a random function. The attack needs 297 queries, with a success probability 0.87, while the previous distinguishing attack on HMAC-MD5 reduced to 33 rounds takes 2126.1 messages with a ...

Problems using MD5 with IPv6

Performance Evaluation, 1996
Summary: The MD5 algorithm has been specified as part of the IPv6 protocol. However, some questions have been raised as to the ability of MD5 to provide the throughput needed for high-speed networks. This paper examines the performance of MD5 on the POWER2 architecture.

A Novel Improvement With an Effective Expansion to Enhance the MD5 Hash Function for Verification of a Secure E-Document

IEEE Access, 2020
MD5 is a one-way cryptographic function used in various fields for maintaining data integrity. The application of a Hash function can provide much protection and privacy and subsequently reduce data usage.

Chosen-prefix collisions for MD5 and applications [PDF]

International Journal of Applied Cryptography, 2012
We present a novel, automated way to find differential paths for MD5. Its main application is in the construction of chosen-prefix collisions. We have shown how, at an approximate expected cost of 239 calls to the MD5 compression function, for any two chosen message prefixes P and P', suffixes S and S' can be constructed such that the concatenated ...

Improved Single-Key Distinguisher on HMAC-MD5 and Key Recovery Attacks on Sandwich-MAC-MD5 [PDF]

Lecture Notes in Computer Science, 2014
This paper presents key recovery attacks on Sandwich-MAC instantiating MD5, where Sandwich-MAC is an improved variant of HMAC and achieves the same provable security level and better performance especially for short messages. The increased interest in lightweight cryptography motivates us to analyze such a MAC scheme. We first improve a distinguishing-

Versatile High-Sensitivity EPR Using Superconducting Spiral Microresonators. [PDF]

Small Methods
A significant sensitivity enhancement in conventional X‐band pulsed EPR is achieved using planar spiral microresonators fabricated from high‐temperature superconducting YBCO. Fully compatible with standard instrumentation, the approach enables high‐fidelity spin control under typical sample conditions.

Adaptive secure malware efficient machine learning algorithm for healthcare data

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Malware software now encrypts the data of Internet of Things (IoT) enabled fog nodes, preventing the victim from accessing it unless they pay a ransom to the attacker. The ransom injunction is constantly accompanied by a deadline. These days, ransomware attacks are too common on IoT healthcare devices.
