Secure and efficient two-party ECDSA signature scheme

Tongxin xuebao, 2021
To solve the easy disclosure of signature private key and excessive concentration of signature rights, a secure and efficient two-party ECDSA signature scheme was proposed for the blockchain based network trading systems.By pre-computing one-time pad ...

Lived and care experiences of chronic musculoskeletal shoulder pain in Australian adults: A qualitative study

Arthritis Care &Research, Accepted Article.
Objectives Australian evidence on lived and care experiences of chronic musculoskeletal shoulder pain (CMSP), irrespective of disorder classification or disease, is limited. However, such evidence is important for person‐centred care and informing local service pathways and care guidelines or standards.

Join Public Key and Private Key for Encrypting Data

, 2021
Data security is a major issue in the digital world. Cryptography is the most use technique for data security. Cryptography is one of the principle of protection of digital data. Encryption and decryption ensure the data confidentiality. The effectiveness of the encryption security depends on the key management, while RSA algorithm uses two keys ...

The Economic Burden of Rheumatoid Arthritis in Low‐ and Middle‐Income Countries: Systematic Review and Meta‐Analysis

Arthritis Care &Research, Accepted Article.
Objective The aim of this systematic review was to synthesise the economic impact of rheumatoid arthritis (RA) on households, health systems, and society in low‐ and middle‐income countries (LMICs). Methods Electronic databases such as PubMed, Web of Science, and CINAHL were searched using keywords related to RA and cost of illness.

Private quantum codes: introduction and connection with higher rank numerical ranges

, 2013
We give a brief introduction to private quantum codes, a basic notion in quantum cryptography and key distribution. Private code states are characterized by indistinguishability of their output states under the action of a quantum channel, and we show ...

Hip morphology‐based osteoarthritis risk prediction models: development and external validation using individual participant data from the World COACH Consortium

Arthritis Care &Research, Accepted Article.
Objectives This study aims to develop hip morphology‐based radiographic hip osteoarthritis (RHOA) risk prediction models and investigates the added predictive value of hip morphology measurements and the generalizability to different populations. Methods We combined data from nine prospective cohort studies participating in the World COACH consortium ...

On the Impossibility of Private Key Cryptography with Weakly Random Keys [PDF]

, 2007
The properties of weak sources of randomness have been investigated in many contexts and using several models of weakly random behaviour. For two such models, developed by Santha and Vazirani, and Chor and Goldreich, it is known that the output from one such source cannot be "compressed" to produce nearly random bits.

Recovering Private Keys Generated with Weak PRNGs [PDF]

, 2013
Suppose that the private key of discrete logarithm-based or factoring-based public-key primitive is obtained by concatenating the outputs of a linear congruential generator. How seriously is the scheme weakened as a result? While linear congruential generators are cryptographically very weak "pseudorandom" number generators, the answer to that question
