Cryptography classes in bugs framework (BF): Encryption bugs (ENC), verification bugs (VRF), and key management bugs (KMN)

Accurate, precise, and unambiguous definitions of software weaknesses (bugs) and clear descriptions of software vulnerabilities are vital for building the foundations of cybersecurity. The Bugs Framework (BF) comprises rigorous definitions and (static) attributes of bug classes, along with their related dynamic properties, such as proximate, secondary and tertiary causes, consequences, and sites. This paper presents an overview of previously developed BF classes and the new cryptography related classes: Encryption Bugs (ENC), Verification Bugs (VRF), and Key Management Bugs (KMN). We analyze corresponding vulnerabilities and provide their clear descriptions by applying the BF taxonomy. We also discuss the lessons learned and share our plans for expanding BF.
