Classification security-based broadcast authentication design method

Abstract

The invention discloses a classification security-based broadcast authentication design method, which relates to solution for realizing the broadcast authentication of a wireless sensor network, and is mainly used for solving the security authentication problem of a broadcast data packet of the wireless sensor network. A security scheme which can meet the security requirement and has minimum overhead is used for different application and messages so as to reduce the overhead of a protocol to the maximum. For the broadcast data packet in the wireless sensor network, different authentication methods are adopted according to different message types. On the basis of deeply analyzing the shortages of the conventional broadcast authentication technology of the wireless sensor network, the broadcast authentication technology which integrates different security levels is provided aiming at a situation that different application has different requirements on security service intensity; and based on a mixed strategy, the security scheme which can meet the security requirement and has the minimum overhead for different application and the messages is adopted so as to reduce the overhead of the protocol to the maximum.

Description

technical field [0001] The invention relates to a solution for realizing wireless sensor network broadcast authentication. It is mainly used to solve the security authentication problem of wireless sensor network broadcast data packets, and belongs to the cross-technical application field of wireless sensor network and information security. Background technique [0002] With the rapid development and maturity of communication technology, embedded computing technology and sensor technology, miniature sensors with perception, computing and communication capabilities have begun to appear and have attracted great attention. This sensor network can coordinately perceive, collect and process various environmental or monitoring object information in the network coverage area, and release it to users who need this information. The sensor network integrates the logical information world and the real physical world, profoundly changing the way of interaction between man and nature; i...

Problems solved by technology

However, due to the limited resources of wireless sensor network nodes, the commonly used public key signature algorithm has too much computational overhead and energy consumption to meet the requirements of wireless sensor networks.

[0005] Existing authentication schemes such as the RSA digital signature algorithm can tolerate the loss of messages and have no authentication delay, but the overhead is high; the one-time signature algorithm has low calculation overhead, but the communication overhead is high; authentication algorithms based on symmetric encryption technology such as μTESLA The overhead is low, but it introduces authentication delay, and there is also the problem of low efficiency of initialization parameter release

Also, none of the known protocols provide protocol security level support
