WebA cryptanalyst's duties may include developing algorithms, ciphers and security systems to encrypt sensitive information and data as well as analyzing and decrypting different types of hidden information, including encrypted data, cipher texts and telecommunications protocols, in cryptographic security systems. Webrecent innovative attack (ADD REFERENCES)) that completely side-step the adversarial model and as expected completely breaks the security of the scheme. However, this only serves as motivation to model stronger adversaries and thereby construct more robust cryptosystems that are provably robust (with respect to the new models).
