Patent number: 10211984Abstract: A domain authority 13 for use in a hierarchy of domain authorities in a hierarchical cryptographic system. The domain authority 13 comprises a user secret key generator 21 for generating a user secret key based on a domain secret key and one or more attribute representations, to obtain a user secret key associated with a set of attributes corresponding to the attribute representations, and wherein the domain secret key is based on a domain secret key of a parent domain authority or a root secret key of a root authority of the hierarchy of domain authorities, and wherein the attribute representations are independent of the hierarchy. A decrypter makes use of the user secret key. An encrypter generates ciphertext decryptable by the decrypter.Type: GrantFiled: September 21, 2012Date of Patent: February 19, 2019Assignee: Koninklijke Philips N.V.Inventors: Muhammad Asim, Tanya Ignatenko, Milan Petkovic

Patent number: 9800555Abstract: A system for attribute-based encryption comprises a first encrypter (11) and a second encrypter (12). The first encrypter (11) comprises an input unit (1) for determining a message and a policy over a set of attributes, wherein the policy comprises a plurality of components, and a first cryptographic unit (2) for generating an encrypted representation of the message and an encrypted representation of the plurality of components. The second encrypter (12) comprises a receiving unit (3) for receiving the encrypted representation of the message and the encrypted representation of the plurality of components, and a second cryptographic unit (4) for transforming the encrypted representation of the message and the encrypted representation of the plurality of components into an attribute-based encrypted message associated with the policy.Type: GrantFiled: July 22, 2013Date of Patent: October 24, 2017Assignee: Koninklijke Philips N.V.Inventors: Tanya Ignatenko, Muhammad Asim

Publication number: 20160070859Abstract: Sequence models are retrieved from a sequences index. The sequence models model DNA or RNA sequences stored in a database, and each comprises a finite memory tree source model and parameters for the finite memory tree source model. One or more DNA or RNA sequences stored in the database are identified as being most similar to a query DNA or RNA sequence based on fitting of the retrieved sequence models to the query DNA or RNA sequence. The sequence models may be context tree weighting (CTW) models {Sx, ?Sx} where Sx denotes the context tree model for the DNA or RNA sequence x stored in the database, and ?Sx denotes parameters of the context tree model Sx. The fitting may include, for each CTW model {Sx, ?Sx}, computing the codeword length for the query DNA or RNA sequence y using the CTW model {Sx, ?Sx.Type: ApplicationFiled: April 30, 2014Publication date: March 10, 2016Inventor: Tanya IGNATENKO
