首先,我们需要回顾一下Regev Encryption加密系统。我们这里的IBE构造,精髓就基于Regev Encryption的一个变种。 如果大家看过我之前的【初探全同态加密】系列的话,那应该会对基于LWE的Regev加密系统有一定的了解。我们在这里快速的回顾一下: KeyGen:首先,我们需要创建一个LWE的问题实例,即创建一个问题矩阵\mathbf{A},然...
Identity-based encryption (IBE) is a special kind of public key encryption (PKE) in which users can benefit from public key encryption without the need for certifying or verifying random-looking public keys. Particularly, a user’s public key can be any arbitrary string, such as an email add...
We propose the first identity-based encryption (IBE) scheme that is (almost) tightly secure against chosen-ciphertext attacks. Our scheme is efficient, in the sense that its ciphertext overhead is only seven group elements, three group elements more than that of the state-of-the- art ...
Identity-based encryption (IBE) is a form of public-key cryptography in which a third-party server uses a simple identifier, such as an e-mail address, to generate a public key that can be used for encrypting and decrypting electronic messages. Compared with typical public-key cryptography, ...
Identity-based encryption is a type of public-key encryption in which a user can generate a public key from a known unique identifier such as an email address), and a trusted third-party server calculates the corresponding private key from the public key. In this way, there is no need to...

1) identity-based encryption 基于身份加密 1. Usingidentity-based encryptionalgorithm,the private information in the short message is securely encrypted and transmitted so that only the designated recipient of this message is able to decrypt and understand what it contains. ...
An identity-based encryption (IBE) scheme (see alsoidentity-based cryptography) is apublic keyencryption scheme in which the public key can be an arbitrary string. For example, if Alice wants to send a message to Bob at bob@yahoo.com, she simply encrypts the message using the string “bob...
