摘　　要：企业信息保密工作的重要性日益突出,提出利用门限密码共享机制,对目前该领域常用的身份加密(Identity-Based Encryption,IBE)算法进行改进,提高密钥管理环节的合理性.将改进后的IBE算法参与到透明加解密机制的执行过程中,实现对后者的显著优化.提出采用EAC算法将原始密文耦合后分块存储,并各自独立执行加解密流程的方案,进一步增强企业电子文件的破译难度.At present,the importance of enterprise information confidentiality has become increasingly prominent.In order to improve the rationality of key management,a threshold cryptographic sharing mechanism is proposed to improve the IBE encryption algorithm which commonly used in this field.The improved IBE algorithm is involved in the implementation of transparent encryption and decryption mechanism,and the latter is significantly optimized.In addition,the EAC algorithm is proposed to store the original ciphertext in blocks after coupling,and the encryption and decryption process is implemented independently,which further enhances the difficulty of enterprise electronic file decoding.
