Neeva: A Lightweight Hash Function
نویسندگان
چکیده
RFID technology is one of the major applications of lightweight cryptography where security and cost both are equally essential or we may say that cost friendly cryptographic tools have given more weightage. In this paper, we propose a lightweight hash, Neeva-hash satisfying the very basic idea of lightweight cryptography. Neeva-hash is based on sponge mode of iteration with software friendly permutation which provides great efficiency and required security in RFID technology. The proposed hash can be used for many application based purposes.

Investigation of Some Attacks on GAGE (v1), InGAGE (v1), (v1.03), and CiliPadi (v1) Variants
In this paper, we present some attacks on GAGE, InGAGE, and CiliPadi which are candidates of the first round of the NIST-LWC competition. GAGE and InGAGE are lightweight sponge based hash function and Authenticated Encryption with Associated Data (AEAD), respectively and support different sets of parameters. The length of hash, key, and tag are always 256, 128, and 128 bits, respec...
متن کاملAn Improved Hash Function Based on the Tillich-Zémor Hash Function
Using the idea behind the Tillich-Zémor hash function, we propose a new hash function. Our hash function is parallelizable and its collision resistance is implied by a hardness assumption on a mathematical problem. Also, it is secure against the known attacks. It is the most secure variant of the Tillich-Zémor hash function until now.
متن کاملLightweight 4x4 MDS Matrices for Hardware-Oriented Cryptographic Primitives
Linear diffusion layer is an important part of lightweight block ciphers and hash functions. This paper presents an efficient class of lightweight 4x4 MDS matrices such that the implementation cost of them and their corresponding inverses are equal. The main target of the paper is hardware oriented cryptographic primitives and the implementation cost is measured in terms of the required number ...

متن کاملA Lightweight Hash Function
In this paper, to match a lightweight digital signing scheme of which the length of modulus is between 80 and 160 bits, a lightweight hash function called JUNA is proposed. It is based on the intractabilities MPP and ASPP, and regards a short message or a message digest as an input which is treated as only one block. The JUNA hash contains two algorithms: an initialization algorithm and a compr...
