Blockchain – A data storage structure that uses a series of data in blocks linked via hash values and/or signatures.
¢entsi – ¢entsi (pronounced “centsi”) is a pseudo crypto-currency that can be used to measure the value of Continuing Professional Education (CPE) claims and generally maps at 1 ¢entsi per hour of CPE
Continuing Professional Education (CPE) – Continuing Professional Education (CPE) is defined as ANY activity related to common Information Security practitioner activities such as attending or giving conference talks, creating or consuming new information security content (such as blog postings, podcasts, videos, etc.), finding, fixing, and other helping deal with security vulnerabilities and incidents to name a few activities. A major aspect of OpenCPEs is letting the market (security practitioners, certification providers, employers, etc.) decide what CPE activities are, and how much they are worth.
Open Cybersecurity Ledger (OCL) – The Open Cybersecurity Ledger (OCL) is a customized blockchain technology developed by CloudSecurityAlliance Labs that ensures privacy
Permissioned Blockchain – A Blockchain that only allows a specific party or parties to write to it.
Permissionless Blockchain – A Blockchain that uses a consensus algorithm such as proof of stake, proof of work or other to decide who is allowed to write records to the Blockchain.
Public Blockchain – A Blockchain that has publicly readable data, it may be permissioned or permissionless.
Validation record – A validation record is a form of secure proof using digital hashing with a cryptographically secure nonce to creates a hash value that cannot be used to reveal the original data that was used to create the validation record.
Validation of claim – A claim combined with a piece of digital evidence (such as an image or a PDF) is validated with a trusted third party, if confirmed it is then processed, and a Secure Proof is created from it, and written to the Blockchain. The evidence has been validated as correct.
Witnessing – A piece of digital evidence (such as an image or a PDF) is processed, and a validation record is created from it, and written to the Open Cybersecurity Ledger Blockchain.
Witnessing with validation – A piece of digital evidence (such as an image or a PDF) is processed, and validated against the issuing entity, for example someone claiming to have a CCSK submits it, and the CCSK evidence is confirmed as valid or invalid, then a validation record is created from it, and written to the Open Cybersecurity Ledger Blockchain.
