In 2013, the crypto community faced significant challenges and advancements. Researchers like Daniel J. Bernstein, Nadia Heninger, and Tanja Lange contributed to the development of indistinguishability obfuscation and functional encryption for general circuits. The year also saw breakthroughs in mathematics, such as a quasi-polynomial algorithm for discrete logarithm in finite fields of small characteristic, which could impact the security of encryption systems. The crypto community was also concerned about the potential vulnerabilities in widely used cryptographic algorithms. For example, the discrete logarithm problem and factoring integers into primes were found to have subexponential-time algorithms, raising concerns about the long-term security of cryptographic systems. Additionally, the use of elliptic curve discrete logarithms was highlighted as a different challenge, with index calculus unlikely to work. In practice, users faced issues with cryptographic implementations. For instance, a user in January 2013 failed to use crypto correctly, highlighting the importance of proper implementation. In February 2013, timing-padding-oracle attacks against TLS were discovered, leading to the need for improved security measures. The TLS algorithm agility was used to mitigate these vulnerabilities. The year also saw the discovery of vulnerabilities in RSA keys from certified smart cards, with researchers factoring 103 keys using the GCD algorithm. This raised concerns about the randomness of cryptographic key generation. Additionally, the NSA's Bullrun program was revealed, which aimed to insert vulnerabilities into commercial encryption systems and collect data from target networks. The Dual_EC DRBG random number generator was also scrutinized, with concerns about its potential backdoor. The NSA's involvement in the development of cryptographic standards, such as NIST curves, was questioned, leading to discussions about the security of these standards. In response to these challenges, the crypto community advocated for the use of elliptic curves and forward secrecy in cryptographic protocols. The year also saw the development of the TweetNaCl library, a simple and efficient cryptographic library designed for use in programming languages. Overall, 2013 was a year of significant developments and challenges in the crypto community, with researchers and practitioners working to improve the security and reliability of cryptographic systems.In 2013, the crypto community faced significant challenges and advancements.
