OpenFHE
OpenFHE is an open-source cross platform software library that provides implementations of fully homomorphic encryption schemes. OpenFHE is a successor of PALISADE and incorporates selected design features of HElib, HEAAN, and FHEW libraries. History PALISADE Development began with the OpenFHE precursor PALISADE (software). PALISADE adopted the open modular design principles of the predecessor SIPHER software library from the DARPA PROCEED program. SIPHER development began in 2010, with a focus on modular open design principles to support rapid application deployment over multiple FHE schemes and hardware accelerator back-ends, including on mobile, FPGA and CPU-based computing systems. PALISADE began building from earlier SIPHER designs in 2014, with an open-source release in 2017 and substantial improvements every subsequent 6 months. Much of the development was done at Raytheon BBN and NJIT. PALISADE development was funded originally by the DARPA PROCEED and SafeWare p ...

Homomorphic Encryption
Homomorphic encryption is a form of encryption that permits users to perform computations on its encrypted data without first decrypting it. These resulting computations are left in an encrypted form which, when decrypted, result in an identical output to that produced had the operations been performed on the unencrypted data. Homomorphic encryption can be used for privacy-preserving outsourced storage and computation. This allows data to be encrypted and out-sourced to commercial cloud environments for processing, all while encrypted. For sensitive data, such as health care information, homomorphic encryption can be used to enable new services by removing privacy barriers inhibiting data sharing or increase security to existing services. For example, predictive analytics in health care can be hard to apply via a third party service provider due to medical data privacy concerns, but if the predictive analytics service provider can operate on encrypted data instead, these priva ...

Cryptographic Software
Encryption software is software that uses cryptography to prevent unauthorized access to digital information. Cryptography is used to protect digital information on computers as well as the digital information that is sent to other computers over the Internet. Classification There are many software products which provide encryption. Software encryption uses a cipher to obscure the content into ciphertext. One way to classify this type of software is the type of cipher used. Ciphers can be divided into two categories: public key ciphers (also known as asymmetric ciphers), and symmetric key ciphers. Encryption software can be based on either public key or symmetric key encryption. Another way to classify software encryption is to categorize its purpose. Using this approach, software encryption may be classified into software which encrypts "data in transit" and software which encrypts " data at rest". Data in transit generally uses public key ciphers, and data at rest generally uses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proxy Re-encryption
Proxy re-encryption (PRE) schemes are cryptosystems which allow third parties ( proxies) to alter a ciphertext which has been encrypted for one party, so that it may be decrypted by another. Examples of use A proxy re-encryption is generally used when one party, say Bob, wants to reveal the contents of messages sent to him and encrypted with his public key to a third party, Charlie, without revealing his private key to Charlie. Bob does not want the proxy to be able to read the contents of his messages. Bob could designate a proxy to re-encrypt one of his messages that is to be sent to Charlie. This generates a new key that Charlie can use to decrypt the message. Now if Bob sends Charlie a message that was encrypted under Bob's key, the proxy will alter the message, allowing Charlie to decrypt it. This method allows for a number of applications such as e-mail forwarding, law-enforcement monitoring, and content distribution. A weaker re-encryption scheme is one in which the prox ...

Residue Number System
A residue numeral system (RNS) is a numeral system representing integers by their values modulo several pairwise coprime integers called the moduli. This representation is allowed by the Chinese remainder theorem, which asserts that, if is the product of the moduli, there is, in an interval of length , exactly one integer having any given set of modular values. The arithmetic of a residue numeral system is also called multi-modular arithmetic. Multi-modular arithmetic is widely used for computation with large integers, typically in linear algebra, because it provides faster computation than with the usual numeral systems, even when the time for converting between numeral systems is taken into account. Other applications of multi-modular arithmetic include polynomial greatest common divisor, Gröbner basis computation and cryptography. Definition A residue numeral system is defined by a set of integers :\, called the ''moduli'', which are generally supposed to be pairwise coprime ...

Post-quantum Cryptography
In cryptography, post-quantum cryptography (sometimes referred to as quantum-proof, quantum-safe or quantum-resistant) refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against a cryptanalytic attack by a quantum computer. The problem with currently popular algorithms is that their security relies on one of three hard mathematical problems: the integer factorization problem, the discrete logarithm problem or the elliptic-curve discrete logarithm problem. All of these problems could be easily solved on a sufficiently powerful quantum computer running Shor's algorithm. Even though current quantum computers lack processing power to break any real cryptographic algorithm, many cryptographers are designing new algorithms to prepare for a time when quantum computing becomes a threat. This work has gained greater attention from academics and industry through the PQCrypto conference series since 2006 and more recently by several workshops on ...

Series A Round
A series A round (also known as series A financing or series A investment) is the name typically given to a company's first significant round of venture capital financing. The name refers to the class of preferred stock sold to investors in exchange for their investment. It is usually the first series of stock after the common stock and common stock options issued to company founders, employees, friends and family and angel investors. Series A rounds are traditionally a critical stage in the funding of new companies. Series A investors typically purchase 10% to 30% of the company. The capital raised during a series A is usually intended to capitalize the company for 6 months to 2 years as it develops its products, performs initial marketing and branding, hires its initial employees, and otherwise undertakes early stage business operations. It may be followed by more rounds ( Series B, Series C, etc). Sources of capital Because there are no public exchanges listing their securi ...

Seed Round
Seed money, sometimes known as seed funding or seed capital, is a form of securities offering in which an investor invests capital in a startup company in exchange for an equity stake or convertible note stake in the company. The term ''seed'' suggests that this is a very early investment, meant to support the business until it can generate cash of its own (see cash flow), or until it is ready for further investments. Seed money options include friends and family funding, seed venture capital funds, angel funding, and crowdfunding. Usage Traditionally, companies that have yet to meet listing requirements or qualify for bank loans, recognize VC as providers of financial support and value added services. Seed money can be used to pay for preliminary operations such as market research and product development. Investors can be the founders themselves, using savings and loans. They can be family members and friends of the founders. Investors can also be outside angel investors, ventu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
