Curve-Based Security Schemes for Automating the Encryption and Signing of Digital Documents in Organizational Environments

Abstract

Sensitive information in organizations is constantly increasing and at the same sense are the risks of attacks that compromise privacy, confidentiality or integrity. The need for automating the tasks for securing data is more evident in big data scenarios. Thus, organizations could maintain tight control over their information using cryptographic techniques, such as document encryption, authentication, and digital signatures. In this paper, we present a case study in document encryption and authentication in organizational environments domains by means of curve-based cryptography. We propose three constructions for documents encryption and signing for acceptable security levels, on the basis of Identity-Based Encryption and Signcryption approaches, both built from elliptic curves. We provide experimentation details that reveal the feasibility of proposed curve-based cryptographic schemes, useful for automating the provision of security services to digital documents in organizational environments.
