After publishing Secure Comparator paper, we've received a number of concerns from the cryptographic community about possible security breach, in case, where one of the parties is intentionally falsifying the protocol. We've adressed these concerns, and, in this blog post and paper update would like to elaborate how and why.

Secure Comparator is a novel authentication technique we're proposing the cryptographic community to evaluate. It can be used as any id/secret pair authenticator in environments, where no trust relationships exist between two parties.

Current technological advancements in authenticating users seems to be sufficient for most cases. However, taking a more detailed look reveals weaknesses and tradeoffs in all existing authentication schemes. Before explaining the methodology and cryptography behind Secure Comparator, our authentication protocol, we wanted to outline reasons for developing it in a brief review of existing authentication methods.

Being asked several times 'Is Secure Session prone to attacks similar to WeakDH/LogJam', we've decided to outline some principal differences, which render Secure Session really secure from these attacks.

When developing new, advanced features of Themis library, we had to extend some of the ECC cryptography available in open source with our own implementation to provide simple point multiplication with random (unknown in advance) point. To achieve that, we've extended Daniel J. Bernstein's implementation of ed25519 with our own math and code. This blog post outlines our direction of thinking.

TL;DR: SSL is huge, inefficient, complex and may present plenty of security threats. For most platforms, it's the best we've got. For some, where it can be configured properly - it's lifesaver. For many - it's the illusion of security. Let's see what applies to your application.
