• Order Revealing Encryption for Cloud Data

    Topic ---------- Order Revealing Encryption for Cloud Data With significant data breaches becoming the daily norm, our approaches to storing data in the cloud, especially with 3rd party providers needs to radically improve. With the “holy grail” of Fully Homomorphic Encryption (FHE) still years away from practicality, Order Revealing Encryption (ORE) offers a compelling stepping stone to significant data security improvements. In this talk Dan will introduce both FHE and ORE, practical examples and how, in particular ORE can allow for new security models for protecting data in the cloud.

He is a passionate technologist and an Entrepreneur who for most of his career has been either a founder or worked in the leadership team of start-ups and medium-sized technology companies. Dan has worked with a variety of technologies ranging from hardware and embedded systems in his early career to modern system languages like Rust and web technologies such as GraphQL and Elixir. Dan has a passion for security and in particular, cryptography. Cryptography engineering is an incredibly hard discipline and Dan hopes to help more engineers use cryptography securely and effectively in their projects via meetup talks and workshops.

  • Cryptographic Systems Based on Linear Codes

    Topic ---------- Cryptographic Systems Based on Linear Codes An introduction to original linear code-based cryptosystems (Niederreiter and McEliece) and showing how linear code-based cryptography evolves after successful structural-based attacks are discovered. Common structural attacks will be demonstrated, as well as the modern systems modifications of the original algorithm. These modifications are classified based on codes used, ciphertext structure and key length. Based on the analysis, the current stage of code-based systems is summarized as well as real-life implementations and discussion of possible standards.
