Abstract: Power dissipation of sequential static latch, implemented in CMOS, may be reduced by removing clocked elements from the circuit. One way to do this may be to replace a clocked digital feedback path with an analog programmable feedback path. An analog programmable feedback path, such as disclosed, may, for example, provide a constant, non-clocked bias by providing constant bias voltages to transistors in the feedback path such that they function as analog devices rather than digital switches. This bias may be adjusted, e.g., to reflect the circuit's operating environment.

Abstract: A method for validating a set of payload data by means of said servers. The method includes validating information related to a set of payload data, based on which a check code has been calculated and encrypted by means of an asymmetric cryptographic key pair (A). The encrypted check code (1.11) has been stored at the archive server and associated with a time stamp, which can be used for validation of the set of payload data. The method may enable a selective revocation of certificates that have been used for signing the set of payload data.

Abstract: The present invention relates to a method and a device for ensuring information integrity and non-repudiation over time. At least one example embodiment provides a mechanism for secure distribution of information, which information relates to an instance in time when usage of cryptographic key pairs associated with a certain brand identity commenced, as well as when the key pairs ceased to be used, i.e. when the key pairs were revoked. The mechanism further allows a company or an organization to tie administration of cryptographic key pairs and a procedure for verifying information integrity and non-repudiation to their own brand. This can be seen as a complement or an alternative to using a certificate authority (CA) as a trusted third party, which CA guarantees an alleged relation between a public key and the identity of the company or organization using the cryptographic key pair to which that public key belongs.

Abstract: The present invention relates to a method for electronic reauthentication of a communication party (12, 22). The method further relates to a device for electronic reauthentication of a communication party. A basic idea of the present invention is to have a communication party, which employs a service, state two different communication addresses, one being a telephone number, via which the communicating party may authenticate herself to a provider (11, 21) of the service.

Abstract: A method and a system are disclosed for identifying a registrant. In at least one embodiment of the present application, a telephone communication address is received from the registrant, and personal information associated with the telephone communication address is obtained from a storage. The association of the personal information and the telephone communication address in the storage is of such a nature that it enables usage of the personal information to get in contact with the person controlling the associated telephone communication address. A first confirmation token is then distributed over a first channel to the registrant and a second confirmation token is received from the registrant over a second channel, and at least one of the first and the second channel is established by way of using the telephone communication address. Finally, correspondence between the first confirmation token and the second confirmation token is verified.

Abstract: Enzymes and other biologically produced materials are recovered from the fermentation broth or other liquor in which they are provided initially and simultaneously distributed throughout particles of a polymeric matrix by dissolving the polymer in the liquor, dispersing the resultant polymer solution in a non-aqueous liquor in the presence of a stabiliser, and azeotroping the dispersion to produce either dry beads or a dispersion of small particles in the non-aqueous liquid.
