Abstract: Techniques for transmitting pilot and traffic data are described. In one aspect, a terminal may scramble its pilot with a scrambling sequence generated based on a set of static and dynamic parameters. The static parameter(s) have fixed value for an entire communication session for the terminal. The dynamic parameter(s) have variable value during the communication session. The terminal may generate a scrambling sequence by hashing the set of parameters to obtain a seed and initializing a pseudo-random number (PN) generator with the seed. The terminal may then generate the pilot based on the scrambling sequence. In another aspect, the terminal may use different scrambling sequences for pilot and traffic data. A first scrambling sequence may be generated based on a first set of parameters and used to generate the pilot. A second scrambling sequence may be generated based on a second set of parameters and used to scramble traffic data.

Abstract: An improved technique involves generating an encoded representation of encrypted forms of a message which includes an institution's digital signature derived from the message. The institution sends the encoded representation to the user's computer. The user transfers an image of the encoded representation from the user's computer to a separate hand-held device. The user then derives the encrypted forms of the message and the institution's digital signature by decoding the image on the hand-held device; the user then decrypts the encrypted forms of the message and the institution's digital signature on the hand-held device. The user then sees the message without interference from an intrusive agent in a MitB attack. Further, the user can verify the institution's identity as the sender of the message by being able to validate the institution's digital signature. In this way, a MitB attack is very likely to be made apparent to the user.

Abstract: A computationally efficient message verification strategy that achieves non-repudiation and resilience to computational denial of service attacks in conjunction with a broadcast authentication protocol that authenticates messages using a combination of a digital signature and a TESLA MAC. When messages are received at a receiver, the verification strategy separates the messages into messages with the same sender identification. The strategy then determines whether the TESLA MAC authenticator is valid for each message and discards those messages that do not have a valid TESLA MAC. The strategy collects the messages that have a valid TESLA MAC for each sender identification and performs a batch verification process on the group of messages to determine if the messages in the group have a valid digital signature. This strategy verifies each message in the group of messages if the batch verification process shows that the group of messages has a valid digital signature.

Abstract: In the computer data security field, a cryptographic hash function process embodied in a computer system and which is typically keyless, but is highly secure. The process is based on the type of chaos introduction exhibited by a game process such as the well known shuffling of a deck of playing cards. Computation of the hash value (digest) is the result of executing in a model (such as computer code or logic circuitry) a game algorithm that models the actual game such as a playing card shuffling algorithm using the message as an input to the algorithm, then executing the card shuffling algorithm on the input. A state (order) of the modeled deck of cards after a shuffle (or multiple shuffles) gives the hash digest value.
