A local area network system was developed to support collaborative science activities in sixth grade classrooms. Analyses of the students' understandings of the system showed they used the social organization of the classroom activities as a frame of reference. Their misconceptions are accounted for by the ways that the system did not properly reflect the… (More)
A tutorial is given on two public key cryptographic systems that provide an alternative to classical cryptographic key management techniques: the RSA system and the SEEK system. The certification of public numbers is discussed.
