Keyed Parallel Hash Algorithm Based on Multiple Chaotic Maps (KPHA-MCM)
IEEE Access, 2021 Hash functions are considered as the core of cryptography, which are the basic technique used for data security. Cryptographic hash functions also can be used to achieve the integrity of large data such as the data stored in a hard disk and set of ...

Bad Directions in Cryptographic Hash Functions
, 2015 A 25-gigabyte “point obfuscation” challenge “using security parameter 60” was announced at the Crypto 2014 rump session; “point obfuscation” is another name for password hashing. This paper shows that the particular matrix-multiplication hash function used in the challenge is much less secure than previous password-hashing functions are believed to be.

A secured cloud‐medical data sharing with A‐BRSA and Salp ‐Ant Lion Optimisation Algorithm
CAAI Transactions on Intelligence Technology, EarlyView.Abstract Sharing medical data among healthcare providers, researchers, and patients is crucial for efficient healthcare services. Cloud‐assisted smart healthcare (s‐healthcare) systems have made it easier to store EHRs effectively. However, the traditional encryption algorithms used to secure this data can be vulnerable to attacks if the encryption key

A trapdoor one-way function for verifiable secret sharing
High-Confidence Computing, 2022 This paper proposes a (t,n)–threshold verifiable secret sharing scheme with changeable parameters based on a trapdoor one-way function. This scheme consists of a generation phase, a distribution phase, an encoding phase and a reconstruction phase.

CAAI Transactions on Intelligence Technology, EarlyView.Abstract Data is the key element that runs the modern society. Large amounts of data are being released day by day as a result of many activities. The digital data is transferred through the Internet which may be vulnerable to attacks while transmitting. Especially, the medical data is observed to be of at most importance.
