September 15 – King Edward I of England issues ordinances for the government of the Kingdom of Scotland. King Edward issues the first commission of Trailbaston – which empowers him to appoint judicial commissions to punish crimes (such as homicide, theft, arson, and rape) and certain trespasses. Edward adds also conspiracy to the list of ...

Definition of Poly1305
Poly1305 takes a 16-byte secret key r {\displaystyle r} and an L {\displaystyle L} -byte message m {\displaystyle m} and returns a 16-byte hash Poly1305 r ( m ) {\displaystyle \operatorname {Poly1305} _{r}(m)} .To do this, Poly1305: 1. Interprets r {\displaystyle r} as a little-endian 16-byte integer. 2. Breaks the message m = ( m [ 0 ] , m [ 1 ] , m [ 2 ] , … , m [ L − 1 ] ) {\displaystyle m=(m,m,m,\dotsc ,m[L-1])} into consecutive 16-byte chunks. 3. Interprets the 16-byte chunks as 17-...
Use as a one-time authenticator
If s {\displaystyle s} is a secret 16-byte string interpreted as a little-endian integer, then is called the authenticator for the message m {\displaystyle m} .If a sender and recipient share the 32-byte secret key ( r , s ) {\displaystyle (r,s)} in advance, chosen uniformly at random, then the sender can transmit an authenticated message ( a , m ) {\displaystyle (a,m)} .When the recipient receives an alleged authenticated message ( a ′ , m ′ ) {\displaystyle (a',m')} (which may have been mod...
Use in Poly1305-AES as a Carter–Wegman authenticator
The original Poly1305-AES proposal uses the Carter–Wegman structure to authenticate many messages by taking a i := H r ( m i ) + p i {\displaystyle a_{i}:=H_{r}(m_{i})+p_{i}} to be the authenticator on the ith message m i {\displaystyle m_{i}} , where H r {\displaystyle H_{r}} is a universal hash family and p i {\displaystyle p_{i}} is an independent uniform random hash value that serves as a one-time pad to conceal it.Poly1305-AES uses AES-128 to generate p i := AES k ( i ) {\displaystyle...
The security of Poly1305 and its derivatives against forgery follows from its bounded difference probability as a universal hash family:If m 1 {\displaystyle m_{1}} and m 2 {\displaystyle m_{2}} are messages of up to L {\displaystyle L} bytes each, and d {\displaystyle d} is any 16-byte string interpreted as a little-endian integer, then where r {\...
Poly1305-AES can be computed at high speed in various CPUs: for an n-byte message, no more than 3.1n + 780 Athlon cycles are needed, for example.The author has released optimized source code for Athlon, Pentium Pro/II/III/M, PowerPC, and UltraSPARC, in addition to non-optimized reference implementations in C and C++ as public domain software.

NaCl one-time authenticator and authenticated cipherusing Poly1305En el año 1305, se produjo un acontecimiento histórico que marcaría el fin de la Orden de los Templarios. Fue durante el reinado de Felipe IV de Francia, conocido como Felipe el Hermoso, cuando se llevaron a cabo una serie de arrestos y torturas a los miembros de la orden.
1305 ( MCCCV ) was a common year starting on Friday of the Julian calendar, the 1305th year of the Common Era (CE) and Anno Domini (AD) designations, the 305th year of the 2nd millennium, the 5th year of the 14th century, and the 6th year of the 1300s decade.
