  • Certificate Transparency Using Blockchain
    Certicate Transparency Using Blockchain D S V Madala1, Mahabir Prasad Jhanwar1, and Anupam Chattopadhyay2 1Department of Computer Science. Ashoka University, India 2School of Computer Science and Engineering. NTU, Singapore Abstract The security of web communication via the SSL/TLS protocols relies on safe distribu- tions of public keys associated with web domains in the form of X:509 certicates. Certicate authorities (CAs) are trusted third parties that issue these certicates. However, the CA ecosystem is fragile and prone to compromises. Starting with Google's Certicate Trans- parency project, a number of research works have recently looked at adding transparency for better CA accountability, eectively through public logs of all certicates issued by certica- tion authorities, to augment the current X:509 certicate validation process into SSL/TLS. In this paper, leveraging recent progress in blockchain technology, we propose a novel system, called CTB, that makes it impossible for a CA to issue a certicate for a domain without obtaining consent from the domain owner. We further make progress to equip CTB with certicate revocation mechanism. We implement CTB using IBM's Hyperledger Fabric blockchain platform. CTB's smart contract, written in Go, is provided for complete reference. 1 Introduction The overwhelming adoption of SSL/TLS (Secure Socket Layer/Transport Layer Security Proto- cols) [4, 33] for most HTTP trac has transformed the Internet into a communication platform with strong measures of condentiality and integrity.

  • Certificate Transparency Description
    Certificate Transparency Description Certificate Transparency is an experimental protocol for publicly logging the existence of Transport Layer Security (TLS) certificates as they are issued or observed, in a manner that allows anyone to audit certificate authority (CA) activity and notice the issuance of suspect certificates as well as to audit the certificate logs themselves. The intent is that eventually clients would refuse to honor certificates that do not appear in a log, effectively forcing CAs to add all issued certificates to the logs. Logs are network services that implement the protocol operations for submissions and queries that are defined in this document. (q.v. IETF RFC 6962) The objectives are described as: Make it very difficult for a CA to issue a TLS certificate for a domain without the certificate being visible to the owner of that domain. Provide an open auditing and monitoring system that lets any domain owner or CA determine whether certificates have been mistakenly or maliciously issued. Protect users from being duped by certificates that were mistakenly or maliciously issued. (q.v. https://www.certificate-transparency.org/what-is-ct) Note that end user TLS clients are not responsible for validating CT logs, all they need to do is enforce a requirement that certificates must have extensions that show that they were issued under these procedures by validating a Signed Certificate Timestamp (SCT) data object presented with the TLS server certificate. Monitors and Auditors have the primary responsibility of detecting anomalous certificates that were never submitted to the logs. According to wikipedia, the implementation status of the standard is as follows: Google launched its first certificate transparency log in March 2013.
