The Public Key Infrastructure Approach to Security. 1  Public Key Infrastructure (PKI) is a set of policies and procedures to establish a secure information exchange. This chapter describes the elements which make up PKI, and explains why it has become an industry standard approach to security implementation. Introduction.
Definition of pK. pK is a negative logarithmic scale of any rate constant. One of the most important examples of pK is pK a, the scale of relative acid strength. pK a is the negative log of the acid dissociation constant (pKa=-log([A-][H+]/[HA])).The Henderson-Hasselbalch equation relates pK a and pH to the relative concentrations of an acid and conjugate base in solution (pH=pKa+log([A-]/[HA])) .ne of the most important examples of pK is pK a, the scale of relative acid strength.
