JA7.2       Definitions

For the purposes of the specifications in Appendix JA7, the following definitions shall apply:

Asymmetric Key Encryption is also known as public key encryption.  This type of encryption uses a pair of keys that are mathematically related: one key for encryption and another key for decryption.  In digital signature processing, a user is assigned a private key that is not shared with anyone, and a public key that is given to anyone who receives digitally signed material from the user.

From California Code of Regulations, Title 2. Section 22003, List of Acceptable Technologies: “The technology known as Public Key Cryptography is an acceptable technology for use by public entities in California…”

All major development environments such as Microsoft and Adobe support PKCS1 asymmetrical key encryption.

Authorized User is a person who has a user account with a Data Registry and is required to provide their correct user name and password in order to access the Data Registry.  Data Registry users may be required to provide professional licensure, certification or credential information, or other qualifying information as condition of receiving authority to provide signatures for certain types of documentation.

Commission means the State of California Energy Resources Conservation and Development Commission, commonly known as the California Energy Commission, also referred to as the Energy Commission.

Commission Compliance Document Repository (also known as an electronic document repository) is an electronic database and document storage software application used for retention of registered electronic Compliance Documents generated by Data Registries, and may also contain data and documentation relevant to other regulatory procedures administered by the California Energy Commission. The Commission Compliance Document Repository shall maintain these retained documents in accordance with Evidence Code sections 1530-1532 (in the custody of a public entity).

Compliance Data Exchange File is an XML file that contains compliance data used to populate a Compliance Document. The Compliance Data Exchange File is part of the Compliance Registration Package.

Compliance Document is one of the following documents required for demonstration of compliance with Title 24, Part 6: Certificate of Compliance, Certificate of Installation, Certificate of Acceptance, Certificate of Verification.

Compliance Registration Package means digitally signed or encrypted digital data that is transmitted to a Data Registry that contains the data required for registering a Compliance Document with a Data Registry, including the Compliance Data Exchange File. A commonly used method is the Zip file format, a data compression and archiving specification that is in the public domain. Files transmitted to a Data Registry using the Zip file format shall be password protected as described in JA7.

Compliance Report Generator is a web service maintained by the Commission that receives standardized document data exchange files from third party software approved by the Commission and produces the document registration package required to complete registered compliance documents in data registries that are approved by the Commission.

Compliance Software is software approved by the California Energy Commission for use in demonstrating compliance with the performance standards in Title 24, Part 6.

Cryptographic Hash Function is a mathematical function that creates a unique number that represents the contents of a block of data or text. In digital signature processing the data or text that the user is digitally signing is called the message. The number generated by the cryptographic hash function is called the message digest. To verify a copy of the message, the cryptographic hash function is applied to both the original message and the copy of the message, and the resulting message digests are compared.  If they are both the same, then the copy is valid.

There is a number of cryptographic hash functions used in digital signature processing. All major development environments such as Microsoft and Adobe support the most commonly used hash algorithm family, SHA-1, SHA-256, SHA-384, SHA-512 hash algorithms which were developed by National Security Agency (NSA).

Data Registry is a web service with a user interface and database maintained by a Registration Provider that complies with the applicable requirements in Appendix JA7, with guidance from the Data Registry Requirements Manual, and provides for registration of residential or nonresidential compliance documentation used for demonstrating compliance with Title 24, Part 6.

Nonresidential Data Registry is a Data Registry that is maintained by a Registration Provider approved by the Commission, that provides for registration, when required by Title 24, Part 6, of all nonresidential compliance documentation. However, nonresidential data registries may not provide for registration of nonresidential Certificates of Verification.

Data Registry Requirements 'Manual is a document that provides additional detailed guidance regarding the functional and technical aspects of the Data Registry requirements given in Joint Appendix JA7.

Digital Certificate is a computer-based record that contains a person's identifying information and the person's digital signature public key, as well as information about the certificate authority that issued the Digital Certificate and the certificate authority's digital signature verifying the authenticity of the person's identity and digital signature. Although California Code of Regulations, title 2, section 22003 (a)(2)(C) states "although not all digitally signed communications will require the signer to obtain a certificate, the signer is capable of being issued a certificate to certify that he or she controls the key pair used to create the signature."

External Digital Data Source (EDDS) is a data transfer service approved by the Energy Commission to operate in conjunction with an approved Data Registry that allows authorized users of a Data Registry to transfer data from a digital data source external to the Data Registry as an alternative to the key-in data entry described in JA7.7.1.1 for registering compliance documents as required by Title 24 Part 6.

Digital Signature an electronic signature that incorporates cryptographic methods of originator authentication, allowing the identity of the signer and the integrity of the data to be verified. The regulations adopted by the Secretary of State that govern the use of Digital Signatures for use by public entities in California are found in the California Code of Regulations, Title 2, Division 7, Chapter 10 Digital Signatures.

Registered Document is a compliance document that has been submitted to a residential or nonresidential Data Registry for retention, verified as complete, and has gone through the registration process so that the Registered Document displays all applicable electronic signatures as well as the Registration Provider's digital certificate and the document's unique registration number. The image of the registered document is accessible for printing or viewing by authorized users of the Data Registry via the Registration Provider’s internet website. The registered document’s unique visible registration number is appended onto the document image by the Data Registry.

A Registered Document meets all applicable requirements in Standards Section 10-103(a), Appendix JA7 and may conform to the guidance given in the Data Registry Requirements Manual.

Registration is the process applicable to electronic Compliance Documents that are verified as complete by the Data Registry, and are electronically signed by all required Data Registry Authorized Users. Registration is initiated when an authorized Registration Signer signs the Compliance Document electronically where subsequently the Data Registry adds the Registration Signer's Electronic Signature to the signature block, appends a unique Registration Number to each page of the document, and then applies the Registration Provider's Digital certificate issued by a Certificate Authority approved by the California Secretary of State to the Compliance Document and displays the Registration Provider's digital signature appearance following the registration signer’s signature block. When Registration is complete, the Data Registry immediately and automatically transmits a copy of the completed Registered Compliance Document to the Commission Compliance Document Repository and also retains a copy of the Registered Compliance Document for use by authorized users for submittals.

Registration Number is an alphanumeric sequence of digits and delimiters appended to a Compliance Document when the document's Registration Signer provides his or her Electronic Signature to the Data Registry to complete Registration for any document. Each Registration Number shall be unique to only one document.
