Matricial Public Key Cryptosystem with Digital Signature
We describe a new public key cryptosystem using block upper triangular matrices with elements in Zp , based on a generalization of the discrete logarithm problem over a finite group. The proposed cryptosystem is very efficient, requiring very few operations and also allows an ElGamal based digital signature scheme. The main benefit is that the […]

FRAMEWORK FOR IMAGE BASED AUTHENTICATION
This paper presents an innovative framework for user authentication based on images. Common user authentication based on passwords has the main drawback of the human difficulty in recalling them. Images are instead easier to remember than passwords. Moreover, modern compression and transmission techniques make image exchange between different devices (e.g. mobile phones, personal digital assistants, […]
