    Abstract: Determining whether to allow access to a message is disclosed. A message is received from a sender. The message is associated with a first time-to-live (TTL) value. A determination is made that the first time-to-live value has not been exceeded. The determination is made at least in part by obtaining an external master clock time. In response to the determination, access is allowed to the message.

    Abstract: Secure directory services are disclosed. A cryptographic hash of a foreign identifier associated with a potential user is received. A determination is made that the received cryptographic hash of the foreign identifier matches a representation of a stored entry. In response to the determination, a transmission of a representation of a native identifier associated with the stored entry is transmitted to the sender of the cryptographic hash of the foreign identifier.

    Abstract: A digital security bubble encapsulation is disclosed. A public key and a device identifier of at least one recipient is requested from a first server. A message containing one or more components is encrypted using a symmetric key. The symmetric key is encrypted with a public key received in response to the request. The encrypted message, the encrypted symmetric key, and the device identifier are encapsulated in a digital security bubble encapsulation. The digital security bubble encapsulation is transmitted to a second server.

    Abstract: A variety of techniques for performing identity verification are disclosed. As one example, a verification request is received from a remote user. The verification request pertains to a cryptographic key. In response to receiving a confirmation from a local user of the local device, a verification process is initiated. A result of the verification process is transmitted to the remote user. As a second example, a verification request can be received at the local device, from a local user of the device. A verification process with respect to the local user is initiated, and a result of the verification process is transmitted to a remote user that is different from the local user.
