Threat-Adjusting Security: BitFlip as an AI-Ready, Post-Quantum cipher

Gideon Samid

Abstract: Generally ciphers project a fixed measure of security, defined by the com- plexity of their algorithms. Alas, threat is variable, and should be met with matching security. It is useless to project insu cient security, and it is wasteful and burden- some to over-secure data. BitFlip comes with threat-adjustable flexibility, established via: (i) smart decoy strategy, (ii) parallel encryption, (iii) uniform letter frequency adjustment tools which enable the BitFlip user to (a) adjust its ciphertexts to match the appraised threat, and (b) sustain security levels for aging keys. The use of these threat-adjusting tools may be automated to allow (1) AI engines to enhance the security service of the cipher, and (2) to enable remote hard-to-access IoT devices to keep aging keys useful, and preserve precious energy by matching security to the ad-hoc threat level. BitFlip may also be operated in a zero-leakage mode where no attributes of a conversation are disclosed, up to full steganographic levels. BitFlip se- curity is two-dimensional: intractability and equivocation, both may be conveniently increased to meet quantum cryptanalytic attacks.
