Kryptografi 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

By hiring a Cryptographer through Freelancer.com on your projects you can ensure that your data remains secure, be it for a simple encryption project or something more complex such as building secure communication networks between multiple users.

    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...

    Smart and Secure Point of Sale Framework with Threat Modeling and Formal Verification Existing PoS (Point of Sale) based payment frameworks are vulnerable as the Payment Application’s integrity in the smart phone and PoS are compromised, vulnerable to reverse engineering attacks. In addition to these existing PoS (Point of Sale) based payment frameworks do not perform point-to-point encryption and do not ensure communication security. We propose a Smart and Secure PoS (SSPoS) Framework which overcomes these attacks. Our proposed SSPoS framework ensures point-to-point encryption (P2PE), Application hardening and Application wrapping. SSPoS framework overcomes repackaging attacks. SSPoS framework has very less communication and computation cost. SSPoS framework also addresses Heartble...

    I'm seeking a qualified individual or a team with expertise in AI and cybersecurity to conduct a red team and blue team simulation. This simulation should primarily focus on: - Testing the effectiveness of my existing firewall configurations - Uncovering any possible weaknesses with the highest accuracy Proficiency in AI simulation and blockchain security is a key requirement for this project. Alongside, hands-on experience with firewall testing and strong attention to detail will be crucial. The simulation's purpose is to push my defenses to the limit and reveal the slightest vulnerabilities that could potentially be exploited. So, a prior exposure to intricate simulations will be a significant add-on. The decisive factor here is not speed, but the depth and precision of vulne...
