IFAC and CPA Canada Release Report on The Professional Accountant’s Role in Data
International Federation of Accountants Chartered Professional Accountants of Canada Professional Accountant Role
2021/5/20
Together with Chartered Professional Accountants of Canada (CPA Canada), today the International Federation of Accountants (IFAC) released The Professional Accountant’s Role in Data.
日前，由中国水产科学研究院长江水产研究所刘文枝博士申请的“一种罗非鱼细小病毒TiPV CPA检测引物及应用”获国家发明专利授权，专利号为ZL201811121682.6。罗非鱼细小病毒是引起养殖罗非鱼暴发性死亡的重要新发病毒病原。快速而准确地进行疾病的诊断与病原检测，是疾病防控的基础。该发明针对罗非鱼细小病毒非结构蛋白基因（NS1）设计引物，建立了具有灵敏度高、特异性强等优点的CPA快速检测方法，...
2020年11月21日，由北京大学第六医院承办的精神医学伦理审查标准学术专题会在山东济南召开的中国医师协会精神科医师分会第十六届年会上成功举办。多位领导、专家带来了高水平的伦理讲座与案例分析。
近期，中国科学院上海光学精密机械研究所强场激光物理国家重点实验室在双CPA激光系统四阶色散(FOD)的被动控制上取得了进展，提出了一种“负正啁啾脉冲放大(NPCPA)”的新型双CPA激光系统设计。相关成果发表于光学著名期刊《光学快报》【Optics Express 28 (21): 31743 (2020)】上。
近期，中国科学院上海光学精密机械研究所强场激光物理实验室研究员梁晓燕课题组在基于钛宝石啁啾脉冲放大器（CPA）结构的低重频双光束相干组束研究中取得新进展，为相干组束技术在超强超短激光领域的应用提供了理论和实验指导。相关成果发表在[Optics Letters 44, 17, 4379 (2019)]。近年来，超强超短激光技术取得快速发展，单路超强超短激光的输出峰值功率已从数太瓦（1012W）提升到...
近年来，超强超短激光技术取得快速发展，单路超强超短激光的输出峰值功率已从数太瓦（1012W）提升到10拍瓦（1015W）。拍瓦级的超强超短激光可以在焦点处产生强度高达1022W/cm2的光场，在激光与物质的相互作用方面具有重要应用。然而，单路超强超短激光的输出能力受到光学元器件口径和损伤阈值的限制。科学家们提出采用并行口径相干组束的方法，用于产生更高强度的超强超短激光输出。
CPA on Hardware Implementation of COLM Authenticated Cipher and Protect it with DOM Masking Scheme
Authenticated Cipher COLM CPA
2019/8/22
Authenticated encryption schemes provide both confidentiality and integrity services, simultaneously. Correlation power analysis (CPA) can be a thread for authenticated ciphers, like all physical impl...
CPA-to-CCA Transformation for KDM Security
public-key encryption key-dependent message security chosen ciphertext security
2019/6/3
We show that chosen plaintext attacks (CPA) security is equivalent to chosen ciphertext attacks (CCA) security for key-dependent message (KDM) security. Concretely, we show how to construct a public-k...

A remark on a success rate model fpr DPA and CPA
Side-channel attacks evaluation metric success rate
2018/11/16
The success rate is the most common evaluation metric for measuring the performance of a particular side channel attack scenario. We improve on an analytic formula for the success rate.
Saber: Module-LWR based key exchange, CPA-secure encryption and CCA-secure KEM
CPA-secure encryption CCA-secure KEM
2018/3/5
In this paper, we introduce Saber, a package of cryptographic primitives whose security relies on the hardness of the Module Learning With Rounding problem (Mod-LWR). We first describe a secure Diffie...
NTRU-LPR IND-CPA: A New Ideal Lattices-based Scheme
Lattices-based Post-quantum Cryptography NTRUEncrypt NTRU-Prime
2018/1/31
In this paper, we propose NTRU-LPR IND-CPA, a new secure scheme based on the decisional variant of Bounded Distance Decoding problem over rings (DR-BDD). This scheme is IND-CPA secure and has two KEM ...
What about Bob? The Inadequacy of CPA Security for Proxy Reencryption
reencryption chosen plaintext security definitions
2017/8/21
Consider three parties: Alice, Bob, and Polly. Alice keeps some encrypted data that she can decrypt with a secret key known to her. She wants to communicate the data to Bob, but not to Polly (nor anyb...
Efficient Compilers for After-the-Fact Leakage: from CPA to CCA-2 secure PKE to AKE
After-the-Fact leakage bounded memory leakage split-state
2017/5/25
The goal of leakage-resilient cryptography is to construct cryptographic algorithms that are secure even if the adversary obtains side-channel information from the real world implementation of these a...
Separating IND-CPA and Circular Security for Unbounded Length Key Cycles
Circular Security every IND-CPA cryptosystem
2017/2/20
One interesting question is whether circular security comes for free from IND-CPA security. Recent works have addressed this question, showing that for all integers n, there exists an IND-CPA scheme t...
