Abstract:
A system for use with a communication network to securely transmit a message thereover from a sender to a recipient, via an intermediary capable of performing electronic services, comprising:a transmitter havingfirst logic to receive the message from a user and to form an encrypted inner envelope using a first cryptographic algorithm, the encrypted inner envelope containing the message in an encrypted form decryptable by the recipient;second logic to form a first information structure associated with the inner envelope, the first information structure containing data identifying the recipient as a destination and identifying desired electronic services;third logic to form an encrypted first information structure using a second cryptographic algorithm, the encrypted first information structure containing the first information structure in an encrypted form decryptable by the intermediary;fourth logic to receive the encrypted inner envelope and encrypted first information structure and to transmit them as a first package on the communication network;an intermediary havingfifth logic to receive the first package and to decrypt the encrypted first information structure, using the second cryptographic algorithm, to determine the identifying data and the desired electronic services;sixth logic to process the electronic services;seventh logic to form a second package, the second package containing the encrypted inner envelope;a receiver havingeighth logic to obtain the second package; andninth logic to decrypt the inner envelope, using the first cryptographic algorithm, to recover the message and to present it to the recipient.
