Black Box Traceable Ciphertext Policy Attribute-Based Encryption Scheme

open access: yesInformation, 2015
In the existing attribute-based encryption (ABE) scheme, the authority (i.e., private key generator (PKG)) is able to calculate and issue any user’s private key, which makes it completely trusted, which severely influences the applications of the ABE ...

Prediction of the individual risk for the development of brain metastases in patients with non‐oncogene‐addicted non‐small cell lung cancer: Real‐world data from the German prospective CRISP registry (AIO‐TRK‐0315)

open access: yesInternational Journal of Cancer, Volume 159, Issue 3, Page 739-749, 1 August 2026.
What's New? Estimating the risk of developing brain metastases may enable earlier diagnosis and treatment, potentially reducing morbidity and mortality. Using the prospective CRISP lung cancer registry, the authors developed and validated a point‐based classifier for the risk of developing first brain metastases in patients with advanced or metastatic ...

Comment on “Secure Data Access Control With Ciphertext Update and Computation Outsourcing in Fog Computing for Internet of Things”

open access: yesIEEE Access, 2018
In this comment paper, we point out a security flaw in a data access control system which is built on ciphertext-policy attribute-based encryption (CP-ABE) and attribute-based signature schemes.

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): short‐term peri‐operative analgesic use

open access: yesAnaesthesia, Volume 81, Issue 8, Page 1057-1067, August 2026.
Summary Introduction An increasing proportion of complex surgical procedures are being performed in the UK as day‐cases, with variable and limited follow up. Discharge prescriptions must provide adequate analgesia, while considering the safety of the patient and public, following best practice guidance and good opioid stewardship.

CP-ABE With Constant-Size Keys for Lightweight Devices

open access: yesIEEE Transactions on Information Forensics and Security, 2014
Lightweight devices, such as radio frequency identification tags, have a limited storage capacity, which has become a bottleneck for many applications, especially for security applications. Ciphertext-policy attribute-based encryption (CP-ABE) is a promising cryptographic tool, where the encryptor can decide the access structure that will be used to ...

Incidence and outcomes of postoperative paralytic ileus after cytoreductive surgery with HIPEC: A population‐based study

open access: yesColorectal Disease, Volume 28, Issue 8, August 2026.
Abstract Background Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is standard treatment for peritoneal metastases in Sweden. Prolonged postoperative ileus (PPOI) is a common complication following major abdominal surgery and is associated with increased morbidity and prolonged hospitalization.

Hodgkin and non‐Hodgkin lymphomas in the post‐antiretroviral therapy era according to HIV virological suppression

open access: yesHIV Medicine, Volume 27, Issue 8, Page 1312-1332, August 2026.
Abstract Objectives Lymphomas remain among the most frequent HIV‐associated malignancies, with risk persisting despite effective virological control. This study describes the clinical, epidemiological and prognostic characteristics of lymphomas (both Hodgkin [HL] and non‐Hodgkin [NHL]) in people living with HIV (PLWH), according to virological ...
