| | | | | What is an LFSR? An LFSR is a Linear Feedback Shift Register. It's a simple way of generating a sequence of numbers that look random. Used in cryptography and in generating pseudo-random numbers, they are interesting because they are so simple. Shift bits and feed a few of them back into the sequence. That's it. Important note: LFSRs are not cryptographically secure on their own. ESPECIALLY 8-bit LFSRs. More on that in the next post on this topic. | |

| | | | | Introduction: Cryptography, the art of secure communication, relies on robust and trustworthy encryption algorithms to safeguard sensitive information. However, concerns about a potential backdoor in the NIST-approved Dual_EC_DRBG random number generator have plagued the encryption community for years. This article examines the history, suspicions, and implications surrounding the controversial algorithm. Background: Dual_EC_DRBG, based on elliptic curve cryptography, was included in NIST's SP 800-90A publication as one of the recommended random number generators for use in cryptography. However, from the beginning, doubts were raised about the algorithm's security and potential weaknesses. Later, it was publicly revealed that the United States National Secu... | |
