摘要： There is provided a method for secure communications. The method includes a computing device receiving a notification comprising a message, a counter value, a signature signed by a signer and based on the message and the counter value, and an indication of the signer. The device obtains a current counter value based on an identity of the signer, checks the signature and compares the counter value with the current counter value; and, if the counter comparison and the signature checking is successful, accepting the message.

摘要： A method of processing a notification that is broadcast by a source server is disclosed. The method includes: receiving, at the computing device, the notification, the notification containing a first message; storing the first message in a message store; determining that the first message is a repeated message of a previous message that was received at the computing device prior to receiving the notification; and associating a message counter value of the first message with the previous message and a message counter value associated with the previous message in the message store.

摘要： A shielding article is provided, for shielding a device enabled for proximity-based communications, for example, NFC-enabled devices. The shielding article comprises a shielding component configured to prevent operation of an antenna of the device used for conducting proximity-based communications, without preventing operation of at least one other antenna of the device when the shielding component is aligned with the antenna used for conducting proximity-based communications. The shielding article may be separate from, or included in an accessory or carrying article and may be fixed or detachably coupled thereto.
