[−][src]Module ibe::kiltz_vahlis_one
Identity Based Encryption Kiltz-Vahlis IBE1 scheme on the BLS12-381 pairing-friendly elliptic curve.
- From: "CCA2 Secure IBE: Standard Model Efficiency through Authenticated Symmetric Encryption"
- Published in: CT-RSA, 2008
Uses SHA3-512 for hashing to identities.
The structure of the byte serialisation of the various datastructures is not guaranteed to remain constant between releases of this library. All operations in this library are implemented to run in constant time.
Structs
| CipherText | Encrypted message. Can only be decrypted with an user secret key. |
| Identity | Byte representation of an identity. |
| PublicKey | Public key parameters generated by the PKG used to encrypt messages. |
| SecretKey | Secret key parameter generated by the PKG used to extract user secret keys. |
| SymmetricKey | A point on the paired curve that can be encrypted and decrypted. |
| UserSecretKey | Points on the paired curves that form the user secret key. |
Functions
| decrypt | Decrypt ciphertext to a SymmetricKey using a user secret key. |
| encrypt | Generate a symmetric key and corresponding CipherText for that key. |
| extract_usk | Extract an user secret key for a given identity. |
| setup | Generate a keypair used by the Private Key Generator (PKG). |
