An IBE Implementation of REESSE1+

摘要：

　　lBE (Identity-based Encryption) technology,no digital certificates,is user-friendly and convenient for back-office management.It simplifies the key management process of a public key cryptosystem and diminishes the cost of application.This paper presents the thought of IBE systems,and analyzes the typical encryption algorithm.The main works are as follows.First,through two SHA-256 Hash mappings,the authors convert a users 72-bit ID into a REESEE1+ public key sequence.Second,from the REESEE1+ key transform,the authors design an algorithm that can use a public key sequence to generate a private key sequence,and analyze its security and time complexity.Finally,the encryption and decryption algorithms of the new IBE scheme are described the same as those of REESEE1+.According to MPP proposed in the REESSE1+ scheme,the security of a private key generated from a public key can be ensured,and according to ASPP in REESSE1+,the security of a ciphertext can be ensured.
