-The Proof of transit mechanism implemented here is based on -Shamir's Secret Sharing algorithm. -The overall algorithm uses two polynomials -POLY-1 and POLY-2. The degree of polynomials depends on number of nodes -to be verified for transit. -POLY-1 is secret and constant. Each node gets a point on POLY-1 -at setup-time and keeps it secret. -POLY-2 is public, random and per packet. -Each node is assigned a point on POLY-1 and POLY-2 with the same x index. -Each node derives its point on POLY-2 each time a packet arrives at it. -A node then contributes its points on POLY-1 and POLY-2 to construct -POLY-3 (POLY-3 = POLY-1 + POLY-2) using lagrange extrapolation and -forwards it towards the verifier by updating POT data in the packet. -The verifier constructs POLY-3 from the accumulated value from all the nodes -and its own points on POLY-1 and POLY-2 and verifies whether -POLY-3 = POLY-1 + POLY-2. Only the verifier knows POLY-1. -The solution leverages finite field arithmetic in a field of size "prime number" -for reasons explained in description of Shamir's secret sharing algorithm. - -Here is an explanation of POT profile list and profile configuration CLI to -realize the above mechanism. -It is best to use the script provided at [iOAM-Devnet] to generate -this configuration. -- **Create POT profile** : set pot profile name <string> id [0-1] -[validator-key 0xu64] prime-number 0xu64 secret_share 0xu64 -lpc 0xu64 polynomial2 0xu64 bits-in-random [0-64] - - name : Profile list name. - - id : Profile id, it can be 0 or 1. - A maximum of two profiles can be configured per profile list. - - validator-key : Secret key configured only on the - verifier/decapsulating node used to compare and verify proof of transit. - - prime-number : Prime number for finite field arithmetic as required by the - proof of transit mechanism. - - secret_share : Unique point for each node on the secret polynomial POLY-1. - - lpc : Lagrange Polynomial Constant(LPC) calculated per node based on - its point (x value used for evaluating the points on the polynomial) - on the polynomial used in lagrange extrapolation - for reconstructing polynomial (POLY-3). - - polynomial2 : Is the pre-evaluated value of the point on - 2nd polynomial(POLY-2). This is unique for each node. - It is pre-evaluated for all the coefficients of POLY-2 except - for the constant part of the polynomial that changes per packet - and is received as part of the POT data in the packet. - - bits-in-random : To control the size of the random number to be - generated. This number has to match the other numbers generated and used - in the profile as per the algorithm. - -- **Set a configured profile as active/in-use** : -set pot profile-active name <string> ID [0-1] -
