Cryptographic software: vulnerabilities in implementations

Abstract

Security and cryptographic applications or libraries, just as any other generic software products may be affected by flaws introduced during the implementation process. No matter how much scrutiny security protocols have undergone, it is — as always — the weakest link that holds everything together to makes products secure. In this paper I take a closer look at problems usually resulting from a simple human made mistakes, misunderstanding of algorithm details or a plain lack of experience with tools and environment. In other words: everything that can and will happen during software development but in the fragile context of cryptography
