Abstract: A method of allowing collaboration on an encrypted document stored in a cloud computing network, the encrypted document associated with a first user having a first user account in the cloud computing network, the method comprising: in response to a request from the first user to share the encrypted document, sending a link to a public network destination to a second user address of a second user; receiving a request via the link from an unconfirmed user to access the data in the encrypted document; requesting of the unconfirmed user to login to a second user account on the cloud computing network; authenticating the identity of the unconfirmed user as the second user; upon authenticating the identity of the unconfirmed user as the second user, decrypting the encrypted document to generate a decrypted document; storing the decrypted document in the first user account; granting the second user access to the decrypted file simultaneously to access granted to the first user; subsequent to the first user or the se

Abstract: This disclosure relates to the provision of cryptographic services to web browsers, and more specifically, to systems and methods for providing cryptographic results to a browser from a cryptographic device over a persistent peer-to-peer connection.

Abstract: A device (102) for generating and storing a cryptographic key pair is disclosed. The device comprises a non-persistent memory unit (116) and a processor (114). The processor (114) is configured to receive a plurality of seeds from a respective plurality of users and combine the seeds to define a composite seed. The processor (114) is further configured to generate the key pair, comprising a public key and a private key (104), using the composite seed and a deterministic key generation method, and to record the private key (104) in the non-persistent memory unit (116).
