Abstract: In a first aspect, the present invention provides a protocol for communications across a securable communication channel between a first device and a second device. The protocol includes the transmission of a plurality of uniquely identifiable messages which each include security-related data, from the first device to the second device. The protocol includes determining whether a subset of messages that are received by the second device comply with at least one predetermined message criterion and are identifiable as having been sent from the first device. In the event that said subset of messages are determined to comply with the predetermined verification criterion (or criteria) and are identifiable as having been sent from the first device, the security-related data is determined to have been successfully communicated to the second device.

Abstract: In a first aspect the present invention provides a method for verifying that a secure association has been formed between a first device and a second device. The method includes, enabling a user of the first device to select a verification indicator, and encrypting the verification indicator using an encryption key of the first device to form cipher text. The cipher text is then communication to the second device using a multi-part communication protocol, and decrypted using an encryption key of the second device to obtain a received verification indicator. The method includes verifying the association is secure if the received verification indicator is the same as the selected verification indicator.

Abstract: There is disclosed a method for verifying that a secure association has been formed between a first device and a second device by comparing a secret key of the first device to a secret key of the second device. The method includes transforming the secret key of the first device and the second device using a predetermined transformation. A user verifiable comparison of the transformed secret key of the first and second devices is performed and if the transformed secret keys of the first and second devices match the association is verified as being secure. The method can include representing the transformed secret keys of the first device and the second device in a user perceptible manner.
