WYSIWYS
In cryptography, What You See Is What You Sign (WYSIWYS) is a property of digital signature systems that ensures the semantic content of signed messages can not be changed, either by accident or intent. P. Landrock, T. Pedersen, "WYSIWYS? -- What you see is what you sign?". Information Security Technical Report, Volume 3, Number 2, 1998, pp. 55-61 Mechanism of WYSIWYS When digitally signing a document, the integrity of the signature relies not just on the soundness of the digital signature algorithms that are used, but also on the security of the computing platform used to sign the document. The WYSIWYS property of digital signature systems aims to tackle this problem by defining a desirable property that the visual representation of a digital document should be consistent across computing systems, particularly at the points of digital signature and digital signature verification. It is relatively easy to change the interpretation of a digital document by implementing changes on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Signature
A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very high confidence that the message was created by a known sender ( authenticity), and that the message was not altered in transit ( integrity). Digital signatures are a standard element of most cryptographic protocol suites, and are commonly used for software distribution, financial transactions, contract management software, and in other cases where it is important to detect forgery or tampering. Digital signatures are often used to implement electronic signatures, which includes any electronic data that carries the intent of a signature, but not all electronic signatures use digital signatures.

Peter Landrock
Peter Landrock (born August 20, 1948 in Horsens) is a Danish cryptographer and mathematician. He is known for his contributions to data encryption methods and codes. Landrock has been active since the 1970s as research scientist and faculty member for Cambridge University and the University of Aarhus and others, and was active for Microsoft and Cryptomathic. He has been visiting professor at Oxford University, Leuven University and Princeton University. Background and career Landrock obtained a diploma in mathematics and physics in 1972 from the University of Aarhus. He received his Ph.D. in mathematics from the University of Chicago in 1974 for his research on elementary abelian and dihedral defect groups, under George Isaac Glauberman and Richard Dagobert Brauer. In 1975, Landrock became associate Professor in the Department of Mathematics at Aarhus University, then full Professor. From 1982 until 1983, Landrock was visiting professor at the Institute for Advanced Study in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptomathic
Cryptomathic is a software company specializing in the area of cryptography for e-commerce security systems. The company develops secure software for the financial and governmental industries. It focuses especially on developing back-end solutions using hardware security modules. Cryptomathic has its headquarters in Aarhus, Denmark. The company was founded in 1986, by three professors from University of Aarhus, among them Peter Landrock and Ivan Damgård. It now operates world-wide with offices in Cambridge, UK; Munich, Germany; San Jose, California, US and Sophia Antipolis, France. Cryptomathic has collaborated in research projects with the Isaac Newton Institute for Mathematical Sciences to develop Cryptomathic's systems for securing messaging between hardware security modules (HSMs). With Bristol University, Cryptomathic conducted research on authenticated encryption between HSMs. Awards and recognition In 2002, Cryptomathic's chief cryptographer Vincent Rijmen was named one ...

Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
