Privacy preserving data mining of distributed data is an important direction for data mining, and privacy preserving clustering is one of the main researches. At present, most privacy preserving clustering algorithms are concentrated on k-means and based on two parties and a trusted third party, clustering results are uncertain and hard to find complex shape clusters, and the protocols are inefficient...
Underwater acoustic communications have found applications in many fields with great developments. Thus, the demand for security of such communications is rapidly growing. Two parties in the communication, after authentication, generally use a secure symmetric key to encrypt all the data they transmit. Thus, an efficient key generation algorithm is in urgent need to guarding the privacy of the communication...
