一种多跳传输环境下安全的数据采集方法
Secure Data Acquisition Method among Multi-hop Transmission Environments
摘要
Abstract
Compressed sensing can efficiently accomplish data acquisition and eliminate the"hot spot"phenomenon in distributed multi-hop networks. However, it cannot provide security protection for data acquisition. Compressed sensing symmetric cryptosystem requires encryption and decryption parties to share the secret keys in advance, needs a secure channel to update the keys and transmit the signal energy during each encryption, and is vulnerable to collusion attacks. In order to solve the problem of data acquisition security in distributed environments, this study extends compressed sensing symmetric encryption(CSSE)to the case of public key,proposes a new cryptographic primitive-compressed sensing public key encryption (CSPKE), defines CSPKE encryption model, and presents a concrete CSPKE algorithm by combing a hard problem on lattices with compressed sensing,proves its indistinguishability against chosen plaintext attack (IND-CPA) on standard model based on the learning with errors(LWE)assumptions. This algorithm makes good use of the matrix feature of lattice cryptogram and well preserves the linear structure of CS, which makes it possible to fuse compressed measurement with encryption in the same step,so it can be very suitable for data secure acquisition in multi-hop environments. In distributed multi-hop environments, CSSE may be difficult in secret key distribution and storage, requires a secure channel to transmit signal energy in every encryption and is vulnerable to collusion attacks. CSPKE compensates the shortcomings of CSSE by adding a little communication cost.关键词
