Cryptography Jobs

Cryptography is the science of protecting sensitive information by transforming it into a code that is illegible to unauthorized users. Cryptographers use mathematics and computer algorithms to create cryptographic protocols and encryption techniques that allow data to be kept secure, in the same way a safe can be used to protect valuables from theft or destruction. Cryptographers are technology professionals specifically trained in the art and science of encrypting digital information, making them extremely valuable assets for businesses, governments, researchers and individuals looking to protect their sensitive data.

The demand for expert Cryptographers has grown significantly in recent years, as new laws have been introduced regulating data security and protection, forcing businesses of all types to recognize the importance of safeguarding sensitive information. As such, Cryptography has become an essential tool in a variety of industries, from healthcare to finance, marketing, law and many others.

Here’s some projects that our expert Cryptographers have made real:

  • Creating presentations around cryptography
  • Translating coding languages relevant to cryptography
  • Constructing comparison studies between different cryptographic algorithms
  • Developing secure network communication protocols through Diffie-Hellman key exchange and AES encryption
  • Enveloping, signing and creating digital messages with .pfx certificates
  • Extracting font names from documents written in Cyrillic
  • Deconstructing cryptosmt tool - Ascon cipher – changing from 5 to 4 size s-box
  • Simulating cryptocurrency risk levels
  • Decrypting digital files using PGP private keys

    I'm looking for a skilled researcher in the field of cryptography, specifically focused on Oblivious Transfer (OT). Find all OT extension implementations and compare them for efficiency and security (sometimes the security assumptions are different hence the security levels are also different. Efficiency can be compared in terms of average memory usage and average time required to complete one OT/OTe of same size in different libraries). Key Requirements: - Strong background in cryptography - Proven experience in conducting research within this field - Ability to evaluate security and efficiency of cryptographic libraries - Familiarity with the implementation of OT in different environments, particularly within OT libraries. The primary goal of this project is to provide an in-dept...
