Cryptographic protocols have been a cornerstone of secure communications among armed forces and diplomatic missions since time immemorial. With easy availability and low cost of computing facilities and Internet, the domain ...

Passwords are the most widely deployed means of human-computer authentication since the early 1960s. The use of passwords, which are usually low in entropy, is delicate in cryptography because of the possibility of launching ...

RSA-OAEP is being used in PKCS #1 2.0 standard for a long time. OAEP (optimal asymmetric encryption padding) provides security strength to RSA and other deterministic one-way asymmetric primitives (trapdoor one-way ...

The Transport Layer Protocol (TLS) ensures con dentiality and integrity of tra c between communicating parties over internet. Almost all web applications commonly use TLS. A block cipher (such as AES, Camellia etc.) is ...

HMAC or keyed-hash message authentication code is a security implementation using cryptographic hash function (where hash function is iterative i.e. classical Merkle-Damgård construction [7] [12]) and a secret key. It ...

Cryptographic hash Functions are widely used for a wide range of applications such as au- thentication of information, digital signatures and protection of pass-phrases. In the last few years, the cryptanalysis of hash ...

In this work, we present the rst side channel collision based key recovery attack on TWINE block cipher with 80-bit secret key and also present the improved version of the work done by Jongsung et al. in on DES.We focus ...
