Alongside the Boneh–Franklin scheme, this is one of a small number of commercially implemented identity-based encryption schemes. It is an application of pairings over elliptic curves and finite fields. A security proof for the algorithm was produced in 2005 by Chen and Cheng. SAKKE is described in Internet Engineering Task Force (IETF) RFC 6508. As a specific method for identity-based encryption, the primary use case is to allow anyone to encrypt a message to a user when the sender only knows the public identity (e.g. email address) of the user. In this way, this scheme removes the requirement for users to share public certificates for the purpose of encryption. ==Description of Scheme== The Sakai–Kasahara scheme allows the encryption of a message $\backslash mathbb$ to an receiver with a specific identity, $\backslash textstyle\; I\_U$. Only the entity with the private key, $\backslash textstyle\; K\_U$, associated to the identity, $\backslash textstyle\; I\_U$, will be capable of decrypting the message. As part of the scheme, both the sender and receiver must trust a Private Key Generator (PKG), also known as a Key Management Server (KMS). The purpose of the PKG is to create the receiver's private key, $\backslash textstyle\; K\_U$, associated to the receiver's identity, $\backslash textstyle\; I\_U$. The PKG must securely deliver the identity-specific private key to the receiver, and PKG-specific public parameter, $\backslash textstyle\; Z$, to all parties. These distribution processes are not considered as part of the definition of this cryptographic scheme. 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「Sakai–Kasahara scheme」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
