LBS Hybrid Encryption Scheme Based on IMSI Pseudonym
Lei Li, Ang Chen, Jing Chen, Zhi Hong Zhang · Advanced materials research · 2013
A hybrid encryption scheme based on the IMSI pseudonym is proposed in this paper. The security model of the scheme is deployed in a cloud environment, and the IMSI pseudonym as a unique identity of a user in the transmission and storage process, which marks and identifies the user, to ensure the privacy of his identity information. Hybrid encryption scheme between communicating parties can be achieved by combining the public-private key pairs updated frequently and symmetric key related to the user identity information, which fully considers the privacy information on security of storage and wireless network transmission and effectively alleviates the current LBS security risks.
