ESUG17: Security Enhancements in Cincom® VisualWorks® 8.3

Posted on in Categories ESUG, Events
  • Title: Security Enhancements in Cincom® VisualWorks® 8.3
  • When: Wednesday, September 6, 2:00 p.m. – 2:30 p.m.
  • Name: Jerry Kott
  • Type: Talk

Abstract:

The upcoming release, Cincom VisualWorks 8.3, includes several security enhancements. In this presentation, Jerry Kott, Senior Software Engineer with Cincom Systems, Inc., will give an overview of what they are and how application developers can take full advantage of Cincom’s pluggable, platform-independent security framework. Among others, topics will include

  • Added support for Authenticated Encryption with Additional Data (AEAD). This family of algorithms uses Advanced Encryption Standard (AES) block cipher as the base encryption algorithm and applies Galois/Counter Mode (GCM) as the block chaining mechanism for data larger than a single block. Examples of use in both OpenSSL libcrypto and Windows BCrypt.dll cryptographic libraries and their interoperability.
  • Added support for Elliptic Curve cryptography on Windows, with a discussion of the limitations imposed by different versions of Windows.
  • High-level discussion of Elliptic Curve Diffie-Hellman (ECDH) key exchange algorithm and Elliptic Curve Digital Signature Algorithm (ECDSA) and how Cincom Smalltalk™ solves the lack of usable implementation in early versions of these algorithms on Windows.
  • An overview of newly added cipher suites to the TLSv1.2 protocol.
  • Current status and plans for TLSv1.3 implementation,

Bio:

Jerry Kott, who has been with Cincom Systems, Inc. for nine years, is a valuable member of the Protocols team responsible for network protocols, security and web application development components of the Cincom Smalltalk Foundation. With Cincom® ObjectStudio® and Cincom VisualWorks both built on the same foundation, this engineering group is responsible for critical improvements that enhance both products. Specifically, Jerry brings a vast knowledge of network protocols and security to this team, which is instrumental in enhancing those components in Cincom Smalltalk

Prior to joining Cincom, Jerry worked as a Smalltalk consultant in a variety of industries including finance, insurance, telecommunications, manufacturing and entertainment. Throughout his career, Jerry has used most of the Smalltalk dialects. He first met Smalltalk/V in his native Czechoslovakia in 1988 while writing his Masters theses at the Faculty of Mathematics and Physics, Charles University of Prague. The political upheaval of 1988/1989 led Jerry to leave Czechoslovakia, and after a year in Austria, his family settled in Canada. While working as a programmer analyst at the TD Bank in Toronto, he was reintroduced to Smalltalk in 1993—this time with the intent of staying with it for good. Jerry’s recollection of his falling in love with Smalltalk can be summed up like this

  1. Day one: This is weird, no source code file?
  2. Day two: This is interesting; I can inspect live objects and send messages to them!
  3. Day three: This is great! I never want to use any other language!

Jerry and his wife also recently got 450 programmers to “bite” on Cincom Smalltalk at BattleSnake 2017 where they came in second place with their Medusa algorithm.  BattleSnake 2017 is a programming competition that was recently held in Victoria, BC, where teams of students and developers build web-based AIs for the classic arcade game “Snake.” While many platforms were used in developing these algorithms by other competitors, Jerry and his wife built their impressive algorithm using Cincom Smalltalk

When not programming in Smalltalk, Jerry uses his passion for photography and film by helping independent filmmakers as a cinematographer. He occasionally dabbles as an associate producer and assistant director. Jerry is also a member of Juan de Fuca Search and Rescue, a volunteer emergency response team that services the rugged western coastline of Vancouver Island off the West Coast of Canada. He recently started practicing with his dog Cindy to be accepted to the training program of British Columbia Search Dog Association. He lives in Victoria, British Columbia
