Abstract: Cryptographic systems and methods that support multiple modes of operation, such as CBC, CTR and/or CCM modes. In one aspect, a method for encrypting data includes reading a plaintext data block from a memory, storing the plaintext data block in an input buffer, encrypting the plaintext data block in the input buffer using a first mode to generate a first ciphertext, storing the first ciphertext in an output buffer, encrypting the plaintext data block in the input buffer using a second mode to generate a second ciphertext. For example, in a CCM mode of operation wherein the first mode is a CTR (counter) mode and the second mode is a CBC (cipher block chaining) mode, the block of plaintext that is initially read from memory and stored in the data input register is applied to both the CTR and CBC modes, thereby reducing a number memory read operations as in conventional CCM modes.

Abstract: A swivel mount for a board binding includes a base mountable to an upper surface of a board, and a swivel plate rotatably mounted on the base for relative swivelling rotation of the swivel plate relative to the base between a ride position and forward-walking positions. A rotational resistance device cooperates between the swivel plate and the base for increasing rotational resistance above that of free-floating rotation but without locking of the swivel plate in a preset locking position when swivelling the swivel plate through the radial arc of the forward-walking positions. A ride position latch releasable locks the swivel plate in the ride position. An actuator releases the ride position latch. The applied force urges the swivel plate to swivel from said ride position to the forward-walking position.
