Abstract

An apparatus configured to generate responses to a multi-encrypted email message. The apparatus is configured to receive an email message comprising a first portion having a first level of encryption and a second portion having a second level of encryption. The apparatus is configured to receive an indication that a first portion of a reply message is in response to the first portion of the received email message. The apparatus is further configured to receive an indication that a second portion of the reply message is in response to the second portion of the received email message. The apparatus encrypts the first portion of the reply message using a first encryption key. The apparatus further encrypts the second portion of the reply message using a second encryption key. Finally, the apparatus transmits the reply message to a server.

Claims20

Dependent claims

An apparatus for generating multi-encrypted email message responses, comprising:

a memory configured to store one or more encryption keys;
a hardware processor communicatively coupled to the memory, and configured to:
receive an email message comprising:
a first portion of the email message having a first level of encryption;
and
a second portion of the email message having a second level of encryption;
receive an indication that a first portion of a reply message is in response to the first portion of the received email message;
receive an indication that a second portion of the reply message is in response to the second portion of the received email message;
determine that a first encryption key stored in the memory for the first portion of the reply message is associated with the first level of encryption of the first portion of the email message;
determine that a second encryption key stored in the memory for the second portion of the reply message is associated with the second level of encryption of the second portion of the email message;
encrypt the first portion of the reply message using the first encryption key in response to determining that the first encryption key is associated with the first level of encryption;
encrypt the second portion of the reply message using the second encryption key in response to determining that the second encryption key is associated with the second level of encryption;
and
transmit the reply message to a server.
