2015 年的 Turing Award 由 Whitfield Diffie 與 Martin E. Hellman 獲得

紐約時報看到今年的 Turing AwardWhitfield DiffieMartin E. Hellman 獲得:「Cryptography Pioneers Win Turing Award」。在 Turing Award 官網上也可以看到對應的說明。

Diffie–Hellman key exchange 是全世界第一個 (1976 年) 在公開頻道上建立 shared secret 的演算法,直到現在都還廣泛的被使用,可以防禦被動式的監聽攻擊:

The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure channel.

現在這個演算法用在 PFS (Perfect forward secrecy),或稱為 FS (Forward secrecy),確保 public key 被破解前的連線記錄不會輕易被破解,於是更確保了資料的安全性:

a secure communication protocol is said to have forward secrecy if compromise of long-term keys does not compromise past session keys.

後來這個演算法也被延用到 Elliptic curve 上,也就是 ECDH,因為不使用 Z_{2^p}Z_p (field) 而是使用 Elliptic curve (group),而大幅降低了可被拿來攻擊的特性,而使得 key 的長度可以比 RSA 小很多。

上一個因密碼學拿到 Turing Award 的是 2012 年得獎的 Silvio MicaliShafi Goldwasser,他們所音發展出來的用以對密碼系統驗證的數學方法而得獎。

而更有名的應該是 2002 年 Ronald L. RivestAdi ShamirLeonard M. Adleman 因為 RSA 演算法而得獎的事情。

在愈來愈多新聞揭露安全與隱私問題後 (尤其是政府對人民的監控),密碼學愈來愈被重視。之前在密碼學領域做出重大貢獻的人也陸陸續續得獎...

2014 年 Turing Award 得主:Michael Stonebraker

今年的 Turing Award 頒給了在資料庫領域上有重要貢獻的 Michael Stonebraker

For fundamental contributions to the concepts and practices underlying modern database systems.

ACM 的頁面上列了不少成就,比較熟的是 PostgreSQL,他是 PostgreSQL 發展重要的關鍵人物:(出自維基百科「PostgreSQL」條目)

PostgreSQL evolved from the Ingres project at the University of California, Berkeley. In 1982 the leader of the Ingres team, Michael Stonebraker, left Berkeley to make a proprietary version of Ingres. He returned to Berkeley in 1985 and started a post-Ingres project to address the problems with contemporary database systems that had become increasingly clear during the early 1980s. The new project, POSTGRES, aimed to add the fewest features needed to completely support types. These features included the ability to define types and to fully describe relationships – something used widely before but maintained entirely by the user.

Google 資助圖靈獎 (Turing Award) 獎金至百萬美金

計算機科學領域裡的最高獎項,Turing Award,在 Google 的資助下,獎金從本來的 25 萬美金提升到百萬美金,ACM 的公告在這邊:「Google to Provide All Funding for Most Prestigious Award in Computing」。

諾貝爾獎的獎金是八百萬瑞典客朗,剛好大約是百萬美金 (約 USD$1.08M)。

這則新聞剛好跟「The Man Who Made the UK Say “I’m Sorry For What We Did To Turing.”」這篇報導一起看。

Leslie Lamport 拿下 2013 年圖靈獎 (Turing Award)

Leslie Lamport - A.M. Turing Award Winner

For fundamental contributions to the theory and practice of distributed and concurrent systems, notably the invention of concepts such as causality and logical clocks, safety and liveness, replicated state machines, and sequential consistency.
