    Abstract: PROBLEM TO BE SOLVED: To provide a system and/or a method for efficiently classifying network packets.
    SOLUTION: The method for efficiently classifying the network packets includes steps for: describing a packet as a feature vector; and mapping the feature vector to a feature space. The method further includes steps for: defining a feature prism; classifying the packet to the feature prism; and deciding whether or not the feature vector matches the feature prism. When the feature vector matches the feature prism, the packet is transferred to a data recipient, when not, the packet is blocked. A device configuration includes: an identification component defining at least one feature of the packet; and a classification component classifying the packet on the basis of at least one characteristic which is defined at least partially.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method that can be used by a person for securely authenticating his identity by issuing a secure identifier.SOLUTION: An authentication apparatus 200 has a processor 208, at least one activator 204 coupled to the processor 208, an internal clock 212, a random number generator 216, an optional additional static memory 220 and a signal output 224, and generates a digital signature using a current time (time identifier), an identified secrete key, and a generated random number, which are called secure identifiers, and issues it. A receiver receives the issued secure identifiers to verify that the secure identifiers have been appropriately sent. The secret key corresponding to a transmitted key identifier is accessed, the validity of the secure identifier is determined using the accessed key, and that the time indicated in the received secure identifier is verified to be within acceptable time tolerances.

    Abstract: Methods devices and systems for detecting return oriented programming (ROP) exploits are disclosed. A system includes a processor a main memory and a cache memory. A cache monitor develops an instruction loading profile by monitoring accesses to cached instructions found in the cache memory and misses to instructions not currently in the cache memory. A remedial action unit terminates execution of one or more of the valid code sequences if the instruction loading profile is indicative of execution of an ROP exploit involving one or more valid code sequences. The instruction loading profile may be a hit/miss ratio derived from monitoring cache hits relative to cache misses. The ROP exploits may include code snippets that each include an executable instruction and a return instruction from valid code sequences.

    Abstract: Method and apparatus for secure transmissions. Each user is provided a registration key. A long-time updated broadcast key is encrypted using the registration key and provided periodically to a user. A short-time updatedkey is encrypted using the broadcast key. The short-time key is available with each broadcast message,wherein sufficient information to calculate the short-time key is provided in an Internet protocol headerpreceding the broadcast content. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key.
