Ntru Cryptosystems, Inc. is a provider of embedded security solutions. It was founded in 1996 by Joseph H. Silverman, Jeffrey Hoffstein, Jill Pipher and Daniel Lieman, four mathematicians at Brown University. In 2009, the company was acquired by Security Innovation.〔( Security Innovation acquires NTRU Cryptosystems, a security solutions provider to the embedded security market )〕 The name Ntru is short for N-th degree ''tru''ncated polynomial ring, or in mathematical notation : which is the underlying ring in which the cryptosystem works. The base ring ''R'' is taken to be the finite field . A detailed description of the encryption can be found in the NTRUEncrypt page. Ntru Cryptosystems developed and markets a Public-key cryptosystem. Ntru has focused on the embedded markets (e.g., cell Phones and RFID chips) where processing power is scarce. One of Ntru's competitors is RSA) Ntru's Cryptosystem provides for both encryption and digital signature called NTRUEncrypt and NTRUSign respectively. Alternative definitions for the acronym "NTRU" are "Number Theorists aRe Us" and "Number Theory Research Unit".〔(【引用サイトリンク】 Three Brown mathematicians build encryption system )〕 NTRU is widely popular owing to its security against quantum computers (i.e. If they ever exist) 〔https://tbuktu.github.io/ntru/〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NTRU Cryptosystems, Inc.」の詳細全文を読む スポンサード リンク
