Algebraic Eraser (AE) is an anonymous key agreement protocol that allows two parties, each having an AE public–private key pair, to establish a shared secret over an insecure channel.〔Anshel I, Anshel M, Goldfeld D, Lemieux S. (''Key Agreement, The Algebraic Eraser and Lightweight Cryptography'' ) Algebraic methods in cryptography, Contemp. Math., vol. 418, Amer. Math. Soc., Providence, RI, 2006, pp. 1–34.〕〔ISO/IEC 29167-20.〕 This shared secret may be directly used as a key, or to derive another key which can then be used to encrypt subsequent communications using a symmetric key cipher. Algebraic Eraser was developed by SecureRF and the company also owns patents covering the protocol. ==Keyset parameters== Before two parties can establish a key they must first agree on a set of parameters, called the keyset parameters. These parameters comprise: * , the number of strands in the Braid, * , the size of the finite field , * , the initial NxN seed matrix in , * , a set of elements in the finite field (also called the T-values), and * a set of conjugates in the Braid Group designed to commute with each other. 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「Algebraic Eraser」の詳細全文を読む スポンサード リンク
