System and method for secure wireless communications using PKI

A method for providing secure mobile communications from a user's wireless device, comprising the steps of:

• (a) storing user-associated information, including at least one digital certificate, on a proxy server;
• (b) receiving a request from said device to access secure information accessible via said proxy server;
• (c) authenticating the user of the wireless device to the server using at least two authentication measures;
• and
• (d) servicing said request from the wireless device via the proxy server.

A wireless communication system, comprising:

• (a) a first data network for receiving and transmitting communications signals, comprising:
• a proxy server for storing digital certificates and user metadata, said server being programmed to issue at least one session key so as to allow user access to said server via a wireless communications device, said proxy server being further programmed to receive communications from said device, determine the authority of said device to access information accessible to said proxy server and determine the authenticity of user information received from said wireless device;
• at least one second server programmed to retrieve information and programming upon receipt of access and request information from said proxy server;
• and
• a program for enabling said retrieved information and programming to be transmitted for suitable display on said wireless device;
• and
• (b) a second data network adapted to transmit to and receive signals from at least one wireless communications device, said device having a memory for storing at least one authentication measure.

A wireless communication system, comprising:

• a proxy server for storing user-associated information, including at least one digital certificate and at least one private key, said proxy server further being capable of issuing at least one authentication measure and accessing and transmitting secure information;
• a wireless communication device having a memory and programming for transmitting and receiving communication signals, including authentication information;
• and
• an initialization device for transmitting to said proxy server at least one digital certificate and a private key associated with a user, as well as information attributed to said wireless communication device, said initialization device further being capable of receiving an authentication measure issued by said proxy server and transmitting said authentication measure to a memory of said wireless device, said authentication measure not to include a digital certificate, a portion of a digital certificate or a hash of a digital certificate.

A computer readable memory, comprising:

• programming for:
• accessing and transmitting secure information within a network;
• storing device and user-associated information;
• receiving and processing requests for initializing a wireless device for use in accessing secure information;
• determining the authority of a device to request secure information;
• determining the authenticity of information delivered via a wireless device in connection with a user having stored user-associated information;
• receiving and processing requests received via a wireless device for secure information;
• transmitting user-associated information in exchange for secure information based on said received requests for secure information;
• and
• transmitting secure information to a wireless device.
