Method of encrypting and transferring data between a sender and a receiver using a network

A method of encrypting and transferring data between senders and receivers using a network, the method performed by a server and comprising:

• receiving from a sender an identifier of a receiver;
• retrieving information specific to the receiver that is accessed according to the identifier of the receiver received from the sender, and using the retrieved information specific to the receiver to encrypt a transfer specific encryption key that is specific to a respective transfer of data between said sender and said receiver and that is used to encrypt the data to be transferred;
• receiving from the receiver, to which the encrypted data and the encrypted transfer specific encryption key has been transferred over the network, the identifier of the receiver and the encrypted transfer specific encryption key;
• and
• retrieving the information specific to the receiver that is accessed according to the identifier of the receiver received from the receiver, and using the retrieved information specific to the receiver to decrypt the encrypted transfer specific encryption key.

A non-transitory computer readable storage medium comprising computer code that when processed by a processor causes said processor to implement a method of encrypting and transferring data between senders and receivers using a network, the medium including:

• computer code for receiving from a sender an identifier of a receiver and generating a transfer specific encryption key specific to a respective transfer of data between said sender and said receiver;
• computer code for encrypting the data to be transferred using the generated transfer specific encryption key;
• computer code for retrieving information specific to the receiver that is accessed according to the identifier of the receiver received from the sender, and using the retrieved information specific to the receiver to encrypt the generated transfer specific encryption key;
• computer code for transferring the encrypted data and the encrypted transfer specific encrypting key over the network for receipt by the receiver;
• computer code for receiving from the receiver, to whish the encrypted data and the encrypted transfer specific encryption key has been transferred over the network, the identifier of the receiver and the encrypted transfer specific encryption key;
• computer code for retrieving the information specific to the receiver that is accessed according to the identifier of the receiver received from the receiver, and using the retrieved information specific to the receiver to decrypt the encrypted transfer specific encryption key;
• and
• computer code for decrypting the encrypted data using the decrypted transfer specific encryption key.

A system comprising:

• one or more memories storing instructions;
• and
• one or more processors configured to execute the instructions to:
• receive an identifier of a receiver from a sender;
• generate a transfer specific encryption key specific to a respective transfer of data between said sender and said receiver;
• encrypt the data to be transferred using the generated transfer specific encryption key;
• retrieve information specific to the receiver that is accessed according to the identifier of the receiver received from the sender, and use the retrieved information specific to the receiver to encrypt the generated transfer specific encryption key;
• transfer the encrypted data and the encrypted transfer specific encryption key over the network for receipt by the receiver;
• receive, from the receiver to which the encrypted data and the encrypted transfer specific encryption key has been transferred, the identifier of the receiver and the encrypted transfer specific encryption key;
• retrieve the information specific to the receiver that is accessed according to the identifier of the receiver received from the receiver, and use the retrieved information specific to the receiver to decrypt the encrypted transfer specific encryption key;
• and
• decrypt the encrypted data using the decrypted transfer specific encryption key.
