A method for distributing a secret key from a key holder H to intended group members M. The method assumes that during the distribution process each party, a group member M and the key holder H, can decrypt and encrypt exchanged information such that the encrypter knows that the decrypter will be the intended party. The method preferably uses a public key / private key encryption technique in which, for example, a trusted Certificate Authority in a public key infrastructure signs the certificates to provide the public keys involved in the encryption. Alternatively, the method, together with a symmetric cipher, uses a shared secret, established in an authenticated mechanism that is outside the information exchanges of the invention. Additionally, the method uses a strong mixing function that takes several items of data as input and produces a pseudorandom authentication (or digest). Inputs to the mixing function include identity stamps that are generated by each member M and key holder H. These inputs can be the identity of the stamp generator, such as a network address, port, or protocol, a timestamp, and / or a secret value that is known only to the stamp generator. The stamps include information to bind member M if generated by key holder H, and to bind key holder H if generated by member M. Consequently, the invention authenticates each communication exchange between member M and key holder H.

A mobile medical facility capable of treating a plurality of patients and being transported over the roadways without requiring extensive transporting means. In general the mobile medical facility includes a trailer. The trailer defines a floor area and has at least a first and second configuration. In the first configuration, the floor area is reduced to allow for transporting of the trailer over the public highways. In the second configuration, the floor area of the trailer is expanded and large enough to support a plurality of beds for treating patients. In some embodiments, the floor area in the second configuration may be at least twice as large as the floor area in the first configuration.
