摘要： Approaches are disclosed for switching transport protocol connection keys. A method of automatically changing a message authentication key at each of two endpoints of a connection in a telecommunications network comprises testing a sequence value received in each of a plurality of data segments on the connection; and selecting a next message authentication key, from among a plurality of stored message authentication keys, for use in authenticating subsequently received data segments, when the sequence value matches a specified characteristic.

摘要： A system, device and method for encrypting plaintext information securely. The system includes a transmitting agent to generate and synchronise a first cipher stream using the plaintext information and a first key, to generate and synchronize a second cipher stream using a second key and a randomizing function to randomize and synchronize a controllable plaintext stream to form a second synchronized cipher stream, and to operate on the plurality of first and second cipher streams using an exclusive disjunction operator to obtain a ciphertext stream; and a receiving agent to decrypt the ciphertext stream.

摘要： A bitstream of each tile in a code sequence is segmented into bitstreams for respective resolution levels (S70). Image key K I is generated (S71). Bitstream key K BS is generated from image key K I using encoding parameters P (S72). Key K Ti of tile Ti is generated from bitstream key K BS using information associated with that tile (S74). Finally, keys corresponding to the segmented bitstreams indicating respective resolutions in tile Ti are generated (S76).

摘要： The invention relates to a method for providing letters and parcels with postal remarks. A client system loads a fee amount from a value transmission centre through a data line, said client system controlling the printing of postal remarks on letters and parcels and said value transmission centre transmitting a data packet to the client system. According to the invention, the method is characterised in that the value transmission centre generates a code and transmits the code to the client system, in that data that are generated in the client system can be encoded with said code in such a way that the value transmission centre can decode them, in that the data are sent from the client system to the value transmission centre and in that the value transmission centre decodes these data, in that the value transmission system forms a random number and then replaces the data, together with the random number, encodes them with a code that is unknown to the client system and with a code that is known to the security module of the client system and then transmits these encoded data to the client system. The invention also relate to a client system for franking letters and parcels and to a value transmission system for using in a franking method.

摘要： According to the invention a method for securing information associated with a content receiver that is part of a conditional access system is disclosed. In one step an object is received by the content receiver wherein the object comprises a number of associated checkpoints. At least one of authentication and authorization is performed with the object when a first checkpoint is encountered. The object is stored. At least one of authentication and authorization is performed with the object when a second checkpoint is encountered. Performance of an action is conditioned upon the encountering the second checkpoint.

摘要： A method and system for selectively encrypting and decrypting different sections of a document provides different access levels in a technique employing different keys. The documents may be encrypted at a document section level ("section" here used according to its general meaning) and uses a different set of encryption keys for each section. A user A with an access level 1 may access only those section encoded with access level 1 plus unencoded sections. An application example of this technique is in hospitals. A patients records may each be segmented into separately-encrypted portions giving access to nurses for only suitable material while giving broader access to doctors. The nurse would be provided with his/her access level private key to gain access to those parts of the document for which nurses have rights. There could also be a level to which only the primary care physician or health care proxy has access.
