Position Mobil Information Encryption Algorithm Based on Key Attributes of Reduced Rank Agent under Cloud Storage

Abstract:

The location mobile social networks information privacy protection under the environment of cloud storage and data security of encryption is researched, the traditional data encryption to rank has higher in the length of ciphertext and private key attributes of large matrix, it defines the length of ciphertext data on customer privacy private property and it cannot be revoked. The encryption complexity and security are not good. An improved encryption algorithm based on key attributes of reduced rank agent is proposed, the proxy ReEncryption technology is taken, the ReEncrypt decryption scheme is designed, and private key attributes of bilinear mapping and reduced rank processing is taken, and a communication channel between the user, CSP, trusted third party and data users is established, and the algorithm is obtained. The simulation is taken for testing the customer information data for privacy protection, the simulation results show that it can ensure the length of ciphertext is relatively small, and it has low computational complexity with more security, and it has the very good practical value in encryption communication and privacy protection fields.
