    摘要： A block encryption method and schemes (modes of operation) that provide both data confidentiality and integrity with a single cryptographic primitive and a single processing pass over the input plaintext string by using a non-cryptographic Manipulation Detection Code function for secure data communication over insecure channels and for secure data storage on insecure media. The present invention allows, in a further aspect, software and hardware implementations, and use in high-performance and low-power applications, and low-power, low-cost hardware devices. The block encryption method and schemes of this invention allow, in yet a further aspect, encryption and decryption in parallel or pipelined manners in addition to sequential operation. In a yet further aspect, the block encryption method and schemes of this invention are suitable for real-time applications.

    摘要： In a distributed sensor network, a method of key management is carried out in several phases, particularly key pre-distribution phase, shared key discovery phase, and as needed, a path key establishment phase. In the key pre-distribution phase, prior to DSN deployment, a ring of keys is distributed to each sensor node, each key ring consisting of randomly chosen keys from a large pool of keys which is generated off-line. A shared key exists between each two key rings with a predetermined probability. In the shared key discovery phase, which takes place upon deployment of the DSN, every sensor node discovers its neighbors in wireless communication range with which it shares keys, and the topology of the sensor array is established by forming secure communication links between respective sensor nodes. The path key establishment phase assigns a path key to selected pairs of sensor nodes in wireless communication range that do not share a key but are connected by two or more links at the end of the shared key discovery phase. The key management scheme also assumes a revocation phase for removal of the key ring of the compromised sensor node from the network. Also, re-keying phase is assumed for removal of those keys with the expired lifetime.

    摘要： A method and system for registration, authorization, and control of access rights in a computer system. Access rights of subjects on objects in a computer system are controlled using parameterized role types that can be instantiated into role instances equivalent to roles or groups. The required parameters are provided by the subject of the computer system, e.g. by a person, a job position, or an organization unit. Furthermore, relative resource sets are instantiated into concrete resource sets and individual resources by using the same parameter values as for instantiating the role types. Authorization and control of access rights include capability lists providing the access rights of the subjects on the objects of a computer system on a per subject basis. Furthermore, access control lists are derived from capability lists, so that access rights of the subjects on the respective objects are provided.
