Abstract: Aspects of the present disclosure relate to systems and methods for exchanging keys within a peer-to-peer network. Exchanging keys within a peer-to-peer network may include generating one or more keys for encrypting and decrypting content that is communicated between one or more client computing devices of a network. The one or more keys may be transmitted over the peer-to-peer network between the one or more client computing devices. A security measure value for each key that has been transmitted may be generated and/or updated based on at least one condition associated with transmitting the one or more keys over the peer-to-peer network. Content may be encrypted and decrypted using one of the one or more keys based on a desired security measure value of the key. All copies of the key used to encrypt and decrypt the content may be deleted such that the content is unrecoverable.

Abstract: Illustrative implementations are described for an automated email message and document shredding system. The implementations provide for generating electronic content and associating the content with a condition upon which the content may self-terminate. Based on the condition, a security context may be determined for the content. The security context determination facilitates the association of a security key corresponding to the security context associated with the content. The security key may be applied to the content to generate encrypted content. A notification of the security key used to encrypt the content, a notification of the condition upon which the content will self-terminate and the encrypted content may then be transmitted to a recipient.
